Progress of solid-phase microextraction coatings and coating techniques. (1/670)
Solid-phase microextraction (SPME) has been popular as an environmentally friendly sample pretreatment technique to extract a very wide range of analytes. This is partly owing to the development of SPME coatings. One of the key factors affecting the extraction performances, such as the sensitivity, selectivity, and reproducibility, is the properties of the coatings on SPME fibers. This paper classifies the materials used as SPME coatings and introduces some common preparation techniques of SPME coating in detail, such as sol-gel technique, electrochemical polymerization technique, particle direct pasting technique, restricted access matrix SPME technique, and molecularly imprinted SPME technique.

An addressable electrode array was used for the production of acid at sufficient concentration to allow deprotection of the dimethoxytrityl (DMT) protecting group from an overlaying substrate bound to a porous reaction layer. Containment of the generated acid to an active electrode of 100 micron diameter was achieved by the presence of an organic base. This procedure was then used for the production of a DNA array, in which synthesis was directed by the electrochemical removal of the DMT group during synthesis. The product array was found to have a detection sensitivity to as low as 0.5 pM DNA in a complex background sample.

The aim of this study was to evaluate hydroxyapatite (HA) coatings produced by dynamic voltage during electrophoretic deposition (EPD). Dynamic voltages from 0 to 200 V were incrementally applied in three interims. The as-deposited coating was sintered at 800 degrees C and its properties evaluated. Structure and phase analyses of both as-deposited and sintered coatings were evaluated by scanning electron microscopy (SEM) and X-ray diffraction (XRD). The HA coatings obtained by dynamic voltage consisted of two layers. While the inner layer was dense and firmly attached to the substrate and contained fine HA particles, the outer layer was porous and contained bigger particles. Repeated deposition was applied to increase the thickness of the coatings. SEM analysis showed that these coatings were free of cracks. In addition, decomposition of HA coatings was not observed until 800 degrees C. (+info)Real-time chemical responses in the nucleus accumbens differentiate rewarding and aversive stimuli. (6/670)

(+info)'Electrochemical techniques' in a medical context refer to the analytical methods that utilize the principles of electrochemistry, such as voltage, current, and resistance changes, to study chemical processes and measure concentrations of ions or molecules at biological interfaces like cell membranes or electrodes.
Electrochemical techniques are a group of analytical methods used in chemistry and biochemistry that involve the study of chemical processes that cause electrons to move. These techniques use an electrochemical cell, which consists of two electrodes (a working electrode and a counter electrode) immersed in an electrolyte solution. An electrical potential is applied between the electrodes, which drives redox reactions to occur at the electrode surfaces. The resulting current that flows through the cell can be measured and related to the concentration of analytes in the solution.
There are several types of electrochemical techniques, including:
1. Voltammetry: This technique measures the current that flows through the cell as a function of the applied potential. There are several types of voltammetry, including cyclic voltammetry, differential pulse voltammetry, and square wave voltammetry.
2. Amperometry: This technique measures the current that flows through the cell at a constant potential.
3. Potentiometry: This technique measures the potential difference between the working electrode and a reference electrode at zero current flow.
4. Impedance spectroscopy: This technique measures the impedance of the electrical circuit formed by the electrochemical cell as a function of frequency.
Electrochemical techniques are widely used in various fields, such as environmental monitoring, pharmaceuticals, food analysis, and biomedical research. They offer several advantages, including high sensitivity, selectivity, and simplicity, making them a powerful tool for chemical analysis.
Electrochemistry is a branch of chemistry that deals with the interconversion of electrical energy and chemical energy, often involving redox reactions at electrodes within electrochemical cells.
Electrochemistry is a branch of chemistry that deals with the interconversion of electrical energy and chemical energy. It involves the study of chemical processes that cause electrons to move, resulting in the transfer of electrical charge, and the reverse processes by which electrical energy can be used to drive chemical reactions. This field encompasses various phenomena such as the generation of electricity from chemical sources (as in batteries), the electrolysis of substances, and corrosion. Electrochemical reactions are fundamental to many technologies, including energy storage and conversion, environmental protection, and medical diagnostics.
'Corrosion' is not a term typically used in medical definitions, it is more commonly associated with materials science and refers to the deterioration of a material (usually a metal) due to chemical reactions with its environment.
Corrosion is a process of deterioration or damage to a material, usually a metal, caused by chemical reactions with its environment. In the medical context, corrosion may refer to the breakdown and destruction of living tissue due to exposure to harsh substances or environmental conditions. This can occur in various parts of the body, such as the skin, mouth, or gastrointestinal tract, and can be caused by factors like acid reflux, infection, or exposure to chemicals.
In the case of medical devices made of metal, corrosion can also refer to the degradation of the device due to chemical reactions with bodily fluids or tissues. This can compromise the function and safety of the device, potentially leading to complications or failure. Therefore, understanding and preventing corrosion is an important consideration in the design and use of medical devices made of metal.
An electrode is a medical device that facilitates the transfer of electrical impulses or signals, either for recording physiological activity from body tissues (such as in EEG or ECG) or for delivering therapeutic electrical stimulation to specific sites (like in deep brain stimulation, TENS, or ICDs).
An electrode is a medical device that can conduct electrical currents and is used to transmit or receive electrical signals, often in the context of medical procedures or treatments. In a medical setting, electrodes may be used for a variety of purposes, such as:
1. Recording electrical activity in the body: Electrodes can be attached to the skin or inserted into body tissues to measure electrical signals produced by the heart, brain, muscles, or nerves. This information can be used to diagnose medical conditions, monitor the effectiveness of treatments, or guide medical procedures.
2. Stimulating nerve or muscle activity: Electrodes can be used to deliver electrical impulses to nerves or muscles, which can help to restore function or alleviate symptoms in people with certain medical conditions. For example, electrodes may be used to stimulate the nerves that control bladder function in people with spinal cord injuries, or to stimulate muscles in people with muscle weakness or paralysis.
3. Administering treatments: Electrodes can also be used to deliver therapeutic treatments, such as transcranial magnetic stimulation (TMS) for depression or deep brain stimulation (DBS) for movement disorders like Parkinson's disease. In these procedures, electrodes are implanted in specific areas of the brain and connected to a device that generates electrical impulses, which can help to regulate abnormal brain activity and improve symptoms.
Overall, electrodes play an important role in many medical procedures and treatments, allowing healthcare professionals to diagnose and treat a wide range of conditions that affect the body's electrical systems.
