A new polymeric amphiphilic molecule for dispersing carbon nanotubes (CNTs) in water, oligothiophene-terminated poly(ethylene glycol) (TN-PEG), was synthesized and its ability to stabilize aqueous CNT dispersions was examined by UV-Vis spectroscopy and transmission electron microscopy.

Compounds containing ethylene oxide groups as a repeating unit, such as glycols and their ethers, have several applications across different industrial fields. (ua.pt)
Ethylene glycol is a useful industrial compound found in many consumer products. (cdc.gov)
Ethylene glycol has a sweet taste and is often ingested by accident or on purpose. (cdc.gov)
Ethylene glycol breaks down into toxic compounds in the body. (cdc.gov)
Ethylene glycol and its toxic byproducts first affect the central nervous system (CNS), then the heart, and finally the kidneys. (cdc.gov)
Indoor Air: Ethylene glycol can release into indoor air as a liquid spray (aerosol), vapor, or mist. (cdc.gov)
Water: Ethylene glycol can pollute water. (cdc.gov)
Agricultural: If ethylene glycol releases as a liquid spray (aerosol) or mist, it may pollute agricultural products. (cdc.gov)
If ethylene glycol releases as a vapor, it is unlikely to pollute agricultural products. (cdc.gov)
Systemic ethylene glycol toxicity can occur through ingestion. (cdc.gov)
Breathing ethylene glycol vapors may irritate eyes and lungs but is unlikely to cause systemic toxicity. (cdc.gov)
Ethylene glycol does not absorb well through the skin so systemic toxicity is unlikely. (cdc.gov)

The polymeric tablets were submitted to different post-treatments (aging, thermal and exposure to compressed gaseous carbon dioxide) and its mechanical, spectroscopic and microstructure properties were assessed. (nih.gov)
In this one-step process, polyurethane was formed by the reaction of the isocyanates with the hydroxyl-functional groups from the polyester, while its gas phase was formed by the generation of carbon dioxide. (iqsdirectory.com)

In both vaccines, the bubbles are coated with a stabilizing molecule of polyethylene glycol. (wikipedia.org)
Form2
Although polyethylene glycol is considered biologically inert, it can form non-covalent complexes with monovalent cations such as Na+, K+, Rb+, and Cs+, affecting equilibrium constants of biochemical reactions. (wikipedia.org)
Polyether polyols in the form of poly tetramethylene ether glycol (PTMEG) were introduced in 1956 by DuPont. (iqsdirectory.com)
The polyurea was later replaced by glycol due to the enhanced properties of the polyurethane created. (iqsdirectory.com)

In vivo biosensing via tissue-localizable near-infrared-fluorescent single-walled carbon nanotubes. (nih.gov)
Single-walled carbon nanotubes are particularly attractive for biomedical applications, because they exhibit a fluorescent signal in a spectral region where there is minimal interference from biological media. (nih.gov)
Although single-walled carbon nanotubes have been used as highly sensitive detectors for various compounds, their use as in vivo biomarkers requires the simultaneous optimization of various parameters, including biocompatibility, molecular recognition, high fluorescence quantum efficiency and signal transduction. (nih.gov)
Here we show that a polyethylene glycol ligated copolymer stabilizes near-infrared-fluorescent single-walled carbon nanotubes sensors in solution, enabling intravenous injection into mice and the selective detection of local nitric oxide concentration with a detection limit of 1 µM. (nih.gov)
To improve therapeutic efficiency of TPP-IOA we chose to employ branched polyethylene glycol (PEG) functionalized single walled carbon nanotubes (SWCNT) and use it as a carrier to deliver mitochondria-targeted TPP-IOA to tissues. (cdc.gov)
