This study investigated the potential for use of electronic noses (e-noses) for early rapid detection and differentiation of bread spoilage before visible signs of growth occur. After 24 h incubation at 25°C it was possible to distinguish Penicillium verrucosum, Aspergillus ochraceus, and Pichia anomala from 3 different species of filamentous fungi before visible growth was observed on unmodified wheat agar using a conducting polymer based e-nose (BH114). Discrimination of controls was possible after 48 h. The BH114 e-nose was able to differentiate between Pseudomonas fragi, Saccharomyces cerevisiae and P. verrucosum growing on 0.97 aw modified flour-based media after only 24 h. The BH114 e-nose was able to discriminate between P. fragi and S. cerevisiae growing in broth cultures and between different aw controls in exponential growth (13.5 h). Discrimination of Staphylococcus aureus growing in different aw broths and from uninoculated controls was achieved after 4.5 h. The BH114 e-nose was ...
Novel gas sensors embroidered into fabric substrates based on polymers/ SWNT-COOH nanocomposites were proposed in this paper, aiming for their use as a wearable electronic nose (e-nose). The fabric-based chemical gas sensors were fabricated by two main processes: drop coating and embroidery. Four potential polymers (PVC, cumene-PSMA, PSE and PVP)/functionalized-SWCNT sensing materials were deposited onto interdigitated electrodes previously prepared by embroidering conductive thread on a fabric substrate to make an optimal set of sensors. After preliminary trials of the obtained sensors, it was found that the sensors yielded a electrical resistance in the region of a few kilo-Ohms. The sensors were tested with various volatile compounds such as ammonium hydroxide, ethanol, pyridine, triethylamine, methanol and acetone, which are commonly found in the wastes released from the human body. These sensors were used to detect and discriminate between the body odors of different regions and exist in various
The electronic nose (E-nose) is a sensing technology that has been widely used to monitor environments in the last decade. In the present study, the capability
In another study, using a set of 13 volatile biomarkers, it was obtained 72% sensitivity and 94% specificity for the identification of LC patients in a population comprising 36 LC patients, 25 patients with chronic obstructive pulmonary disease (COPD), 35 smokers and 50 non-smokers [18]. An alternative method to this conventional technique is based on the so-called "electronic-nose" devices (e-nose). Bio- inspired, an e-nose system performs odor detection using an array of cross-reactive chemical sensors, where every constituent sensor from the array provides a different response upon exposure to a gaseous sample [19]. Sensors combined responses are used to establish odor-specific response patterns by applying pattern recognition algorithms and classification techniques. Thus, the e-nose system is trained for the selective detection of a target odor. The identification of any unknown sample is performed by comparing the pattern generated by the e-nose upon exposure to the unknown odor with the ...
An electronic nose is defined as a sensors array in which each sensor results partially specific to detect a wide number of odorous molecules. The EN is provided with a software system to perform the pattern recognition. Consequently, this device constitutes a real "olfactory robot" which measurement system could be compared with the human olfactory system. The MOSES II EN [9] contains two modules of gas sensors, one of them composed of eight quartz microbalance sensors (QMS). This type of sensors consist of vibrating quartz crystals covered with polymeric selective coatings on which gases are adsorbed. The initial vibration frequency (n0) of crystals decreases according to the mass increase due to the gases adsorption [10] and the difference between n0 and the final frequency (nf ) results proportional to the adsorbed gas concentration. The other module of sensors (SnO2) is composed by eight pure and doped semiconductive SnO2 sensors. Doping with different elements increases SnO2 selectivity ...
An electronic nose "smells" volatile organic compounds (VOCS) which can be characteristic for the disease of a patient. Clinical applications are numerous. At the department of pulmonlogy they are used in research settings to detect and discriminate for instance asthma, COPD, sleep apnea and lung cancer. The main disadvantages of the electronic noses used nowadays are that they are relatively large, the sensors are expensive, measurements might be time consuming and results often can not be presented real-time. These problems can be solved when using an electronic nose based on so-called cantilever technology. The main goal of this project is to develop a clinical applicable miniaturized electronic nose at the University Twente which will be tested and validated at the lung function department of the MST-hospital Enschede.. Dr. Ir. Frans de Jongh (MST/UT/AMC), Dr P.L.P.D.M. van der Valk (MST), Drs M. Eijsvogel (MST), Dr. Ruud Steenwelle (UT), Prof. Dr. Ing. Guus Rijnders (UT), Prof. Dr.Ing. ...
The purpose of this study was to determine the influence of aging time on the development of the aroma characteristics of beer. Volatiles produced from Sleeman Cream Ale during aging for up to 28 days at -1 C were sampled periodically and monitored by a trained sensory panel, by headspace analysis with an electronic nose (EN), and by solid phase microextraction coupled with gas chromatography-mass spectrometry. All three types of analyses discriminated between groups of samples taken early, in the middle, and at the end of the aging periods and separated aged beer into two or three distinct clusters. Intertrial differences were observed and were attributed to production variations. The balance of sweet and bitter notes was optimum at 14 and 21 days of aging. In addition, the EN was able to distinguish finished beer made after different periods of aging, while the sensory panel was not. The results suggest that the EN can complement traditional chemical and sensory approaches to the optimization of beer

This ongoing development places high demands on achieving quality at all levels, particularly in terms of food safety, integrity, quality, nutrition, and other health effects. Food product research is required to convert the initial product idea into a formulation for upscaling production with ensured significant results. Sensory evaluation is an effective component of the whole process. It is especially important in the last step in the development of new products to ensure product acceptance. In that stage, measurements of product aroma play an important role in ensuring that consumer expectations are satisfied. To this end, the electronic nose (e-nose) can be a useful tool to achieve this purpose. The e-nose is a combination of various sensors used to detect gases by generating signals for an analysis system. Our research ...
This study evaluated two electronic nose systems (conducting polymer and surface acoustic wave-based) to differentiate volatiles of grapes and wines treated with an aqueous ethanol spray (5% v/v) at veraison. Ethanol spray induced fruit ethylene production immediately post-treatment, which then declined progressively. Electronic nose evaluations of grape volatiles were compared with Cabernet franc and Merlot physicochemistry, and with wine GC and aroma sensory data. Canonical discriminant and principal component analysis found that both electronic nose systems and the physicochemical measures (Brix, TA, pH, color intensity and hue, total phenols, glycosides, and berry weight) were able to discriminate between ethanol-treated and untreated grapes and wines for both cultivars. Grape physicochemical treatment differences were due mainly to variations in hue, phenolic-free glycosides, and total phenols. Aroma sensory evaluations using a consumer panel differentiated between ethanol treatments and ...
Lung cancer is one of the most serious and common cancer types of today, with very uncomfortable and potentially cumbersome diagnostic techniques in x-ray, CT, CT-PET scans, bronchoscopies and biopsies. Completing all these steps can also take a long time and be time consuming for hospital staff. So finding a new safer and faster technique to diagnose cancer would be of great benefit.. The objectives of this pilot study is to create an effective data storage system that can be scaled for larger data sets in a later study. The aim was also to see whether a E-nose can be used to find the differences in smell-prints from a healthy lung and a cancerous lung. As well as seeing if the E-nose can distinguish samples drawn from the lungs from exhaled air samples.. Samples were taken on patients by the staff at "Lung kliniken" at Link¨oping University Hospital during a bronchoscopy on patients with one-sided lung cancer. These samples were then analyzed by the E-nose which sensory response is later used ...
Identifying the inflammatory phenotype of asthmatic patients requires a time-consuming methodology, personnel and technical resources. The electronic nose is a device capable of detecting volatile organic compounds (VOCs) present in the gas phase of human respiration. Objectives: To compare the profiles of VOCs in the air exhaled by the electronic nose with bronchial inflammatory phenotypes of asthma who attend outpatient. Methods: A total of 44 asthmatic patients were included (16 with eosinophilic asthma, 8 with neutrophilic asthma and 20 with paucigranulocytic asthma). All patients underwent the same day of the visit an: induced sputum, pulmonary function studies and fractional exhaled nitric oxide. Asthmatic patients were classified as induced sputum cellularity (inflammatory profile). The determination of VOCs in the exhaled air is conducted through an electronic nose Cyranose 320 (Smith Detections, Pasadena, CA) according to the method described by Dragonieri S, et al. The breathprints ...

Biosensors such as e-nose and e-tongue can play an important role in standardization of medicinal herbs instead of using traditional physical methods. Electronic nose helps to identify different kind of red ginseng [4]. It was also used to identify different quality of herbal tea [5]. Storage of herbal medicine is one of an important issue that needs to be addressed. It may affect the bio active compounds. Recent studies on Lonicera japonica had found e-nose to be effective to assess the storage condition [6]. With the development of advance image capturing platform such as machine vision system can helps to identify the difference between mature and immature fruits and other part of plants. The external quality on Harumanis Mango was evaluated using this technique [7]. The identification of medicinal herbs was previously performed manually with the help of taxonomist. With advance embedded portable device using image processing technique can helps to identify medicinal plants in any part of ...
Pretty soon, we could all be walking around with nearly invisible personal chemical sensors. The UK-based company Peratech announced earlier this year theyve created a VOC-sensor only a few microns thick, small enough to be easily incorporated into fabrics. The technology uses VOC-absorbing polymers that swell when exposed to the toxins. This swelling causes particles to move apart, changing their electrical resistance. The sensor interprets this resistance and alerts the person wearing it when VOCs reach dangerous levels, as well as when the levels go back down. Caltech chemist Nate Lewis and his colleagues are also developing a sensor to detect chemical vapors, though this one would be attached to smartphones rather than clothing. The "electronic nose" is based on the same principles as Peratechs--polymer composites, swelling and electrical resistance. Lewis and his colleagues see a broader use for their e-nose than just measuring home toxins, such as medical diagnostics based on a patients ...
In the last year many works have been conducted to find rapid and simple ways to early detection of water microbial contamination. It is proved that the Electronic Nose (EN) technique can be successfully utilized as a method to detect the presence of some bacteria like cyanobacteria or Escherichia coli or Enterobacter aerogenes, and for the detection of chemical contamination. Most of the waterborne bacteria are well known and no dangerous for human healthy, but are responsible of some of the most problematic odor contamination in potable water. Most of the bacteria commonly found in water supply networks are generally ubiquitous, due to their simple nutritional requirements and ability to utilize many different organic compounds as energy sources. In fact, they are able to reduce sulfur and selenium, leading to the appearance of off-odors usually described as wet cloth, cockles, butane, rubber and rotten eggs. In this work a new EN instrument was applied to monitoring the off-flavor of drinking ...

Abstract: It is crucial for the wine industry to have methods like electronic nose systems (E-Noses) for real-time monitoring thresholds of acetic acid in wines, preventing its spoilage or determining its quality. In this paper, we prove that the portable and compact self-developed E-Nose, based on thin film semiconductor (SnO2) sensors and trained with an approach that uses deep Multilayer Perceptron (MLP) neural network, can perform early detection of wine spoilage thresholds in routine tasks of wine quality control. To obtain rapid and online detection, we propose a method of rising-window focused on raw data processing to find an early portion of the sensor signals with the best recognition performance. Our approach was compared with the conventional approach employed in E-Noses for gas recognition that involves feature extraction and selection techniques for preprocessing data, succeeded by a Support Vector Machine (SVM) classifier. The results evidence that is possible to classify three ...
Annette McWilliams is hoping her Canadian Cancer Society grant will help prove that an electronic nose can sniff out lung cancer in its early stages.. As a respirologist, Dr McWilliams sees far too many patients with advanced lung cancer. "Lung cancer kills more people than any other cancer. And the reason is that 80% of cases are diagnosed at an advanced stage. Its not very often that you can offer curative treatment to your patients. I find that disheartening.". The complexity of the lungs makes early detection difficult. A small tumour can easily hide in the intricate web of bronchial tubes and alveoli. But perhaps cancer cells can be detected in another way: through our breath.. Thats where the electronic nose comes in. This small hand-held device - "it looks like the old cell phones we used back in the early 90s" - collects breath samples and looks for compounds called volatile organic compounds. These are emitted by cancer cells and the surrounding tissues and then released through the ...
Authors: Kodogiannis, V.S. , Petrounias, I. , Lygouras, J.N. Article Type: Research Article Abstract: Current clinical diagnostics are based on biochemical, immunological or microbiological methods. However, these methods are operator dependent, time consuming, expensive and require special skills, and are, therefore, not suitable for point-of-care testing. Recent developments in gas-sensing technology and pattern recognition methods make electronic nose technology an interesting alternative for medical point-of-care devices.

Introduction. Asthma exacerbations are hallmarked by increased airway inflammation. Exhaled metabolites are associated with biomarkers of inflammation (Fens ERJ 11; Ibrahim Thorax 11). We investigated whether profiles of exhaled biomarkers (breathprints) measured by electronic noses (eNoses) are associated with loss of control/exacerbation after ICS withdrawal.. Methods. 23 patients (6 male; 28±10 yr) with moderate to severe persistent asthma on ICS (≥500 µg fluticasone) were included. Exhaled metabolites (VOCs), FeNO and sputum cell counts were measured at baseline (T1), during loss of control or exacerbation (Reddel AJRCCM 09) (T2) and after recovery (T3=T2 + 4 weeks). VOCs were measured by eNose platform (158 sensors; metal oxide, polymer, quartz microbalance, IMS). Breathprints were created from sensor values by principal component (PC) analysis. Mixed model and correlation analysis were used.. Results. 22 patients experienced a loss of control. Breathprints changed significantly ...
Gastrointestinal side effects are said to be commonplace in radiotherapy patients and can occasionally be severe, yet there is no existing means of predicting which patients will suffer from them.. The results of the pilot study, published in the journal Sensors, outline how the use of an electronic nose and a newer technology, FAIMS (Field Asymmetric Ion Mobility Spectrometry) might help identify those at higher risk.. Warwick Medical School, working in collaboration with the School of Engineering and The Royal Marsden NHS Foundation Trust, led by Dr J Andreyev, carried out a pilot study to look into the relationship between levels of toxicity in the gut and the likelihood of experiencing side effects.. In the simplest terms, we believe that patterns in toxicity levels arise from differences in a patients gut microflora, said Dr Ramesh Arasaradnam, of Warwick Medical School and gastroenterologist at University Hospitals Coventry & Warwickshire. By using this technology we can analyse stool ...
Grand Challenges Canada, a government-funded development agency, and the Bill & Melinda Gates Foundation are injecting $950,000 to support the development of this potentially ground-breaking technology.

The present invention generally provides improved devices, systems, and methods for measuring materials with NMR and/or MRI. Exemplary embodiments provide a sensor array for NMR mapping of the material. For example tissue can be measured with the sensor array mounted on a probe body having a distal portion which can be inserted through a minimally invasive aperture. While many tissues can be measured and/or diagnosed, one exemplary embodiment includes a probe adapted for insertion into a lumen of a blood vessel. The sensor array can provide improved spatial resolution of tissue and/or tissue structures positioned near the sensor array to diagnose potentially life threatening diseases, for example a fibrous cap covering a vulnerable plaque. In specific embodiments, the sensors are attached to an expandable member, for example a balloon, which can be inflated to urge the probe sensors radially outward to position the sensors near the tissue structures.

A gas detection circuit for use in selectively detecting a predetermined gas has a plurality of gas sensors coupled to a sensor measuring circuit. Each gas sensor has a different response to the predetermined gas at a predetermined concentration. The sensor measuring circuit measures a conditioned state of each gas sensor and transmits the measurements to a cross checking circuit which determines whether the conditioned state of each gas sensor is within a corresponding window of upper and lower limit values thereby indicating the possible presence of the predetermined gas by the corresponding gas sensor. Following the testing of the conditioned state of each gas sensor, the cross checking circuit transmits a signal indicating which of the gas sensors indicates the possible presence of the predetermined gas and if all sensors are within corresponding windows, representing detection of the gas, another signal is transmitted to trigger an alarm or other warning system.
