Supermolecular quantum dots (QDs) nanofluids have been firstly proposed and synthesized by virtue of the strong inclusion interactions between α-cyclodextrin (α-CD) and polyethylene glycol (PEG) chains, resulting in tunable liquid-like behaviour, and controllable assembly of single QDs.

Polyethylene glycol has been shown to bind to the molten globule intermediate on the bovine carbonic anhydrase B folding pathway. The mechanism of this interaction has been extensively probed. Polyethylene glycol (PEG) binds weakly to the molten globule first intermediate as measured by hydrophobic interaction chromatography, but PEG does not bind to either the native state or the second interm...

Endoscopy of the colon requires adequate cleansing of the entire bowel. Several laxative regimens have been propagated, but bowel preparation with polyethylene glycol (PEG) solution is popular because of the easy application and good cleansing results. Although very safe in daily use, complications of this bowel-cleansing procedure have been reported and aspiration of the PEG solution is a poss...

In this study, polyethylene glycol (PEG) and vinyltriethoxysilane (VTES) were used in different proportions to produce a series of PEG-VTES copolymers. The copolymer molecular structures were confirmed by FTIR spectroscopy. In addition, their surface activities were evaluated by evaluating the surface tension, contact angle, and foaming properties. The results showed that these surfactants exhi...

A small interfering RNA (siRNA)-loaded polyelectrolyte constructed with branched polyethylenimine (bPEI) and copolymers, consisting of polyethylene glycol (PEG), histidine (His), and glutamic acid (Glu), was developed in order to provide a tumor acidosis-triggered delivery system with low cytotoxicity.

Amphiphilic cadmium selenide (CdSe) nanoparticles were prepared by surface functionalization with novel ligands 1 and 2, composed of pyridine moieties substituted in the 4-position with polyethylene glycol (PEG) chains.

Brighter SERRS nanotags ideal for improved SERRS imaging were prepared by the controlled addition of electrolyte producing a dimer enriched solution, which was incubated with a Raman reporter before being stabilised by a polyethylene glycol (PEG) shell.

silicon is known to ameliorate the deleterious effects of drought on plant growth. we evaluated growth of wheat (triticum aestivum l. cv. chamran) under water-deficit stress induced by polyethylene glycol as affected by si application. in this article, the effects of si (as potassium silicate) on some parameters related to growth, chlorophyll concentration relative water content (rwc), electrol...

Acute repair of crushed guinea pig spinal cord by polyethylene glycol. We have studied the responses of adult guinea pig spinal cord white matter to a standardized compression within a sucrose gap recording chamber. This injury eliminated compound action potential (CAP) conduction through the lesion, followed by little or no recovery of conduction by 1 h postinjury. We tested the ability of pol...

The Cosmetic Ingredient Review (CIR) Expert Panel assessed the safety of 131 alkyl polyethylene glycol (PEG)/polypropylene glycol ethers as used in cosmetics, concluding that these ingredients are safe in the present practices of use and concentration described in this safety assessment when formulated to be nonirritating. Most of the alkyl PEG/PPG ethers included in this review are reported to...
