Efficient iodine capture by biocompatible PEG-based deep …
Sep 1, 2019 · Polyethylene glycol (PEG) possesses the merits of no toxicity, high biocompatibility, high biodegradation and low cost. Here, we for the first time design a series of PEG-based DESs for efficient iodine capture. PEG:thiourea+ethanol …
Polymeric Iodophors: Preparation, Properties, and Biomedical ...
Dec 19, 2020 · Linear polyethylene glycol (PEG) is capable of forming complexes with molecular iodine in solution and in a solid state . The PEG–iodine interaction was studied as dependent on the molecular weight of PEG [ 63 ].
Detection and molecular weight determination of polyethylene …
Feb 1, 1992 · This article describes a general method for detecting pegylated proteins directly after SDS-PAGE. The proteins to which polyethylene glycol (PEG) molecules are attached are stained with a barium iodide solution. The staining is based on the formation of a barium iodide complex with PEG.
Effects of barium chloride adsorbed to polyethylene glycol (PEG ...
This study investigated the effects of BaCl<sub>2</sub> adsorbed to polyethylene glycol (PEG) microspheres on human blood mononuclear cells (MN) co-cultured with breast cancer cell lines (MCF-7).
A molecular architectural design that promises potent …
Mar 5, 2021 · Among the complexes, the flexibly linear complex consisting of one Mel terminally connected with a long-chained PEG (e.g., PEG 12k –1*Mel) shows the most pronounced improvement in performance...
Molecular insights into the interactions between PEG carriers and …
Jul 22, 2024 · It is crucial to recognize that the PEG polymer can form both unbound (non-covalent interactions) and bound (covalent bonding) complexes with drug molecules. The behavior of these two distinct...
Potassium iodide–polyethylene glycol catalyzed cycloaddition …
Aug 8, 2018 · We proposed that one molecule of KI salt reacts with one unit of PEG-400 in situ to afford the [K + {PEG}I −] complex (Scheme 3), 29 which may act as the true catalyst for such a cycloaddition reaction.
Complexation of Molecular Iodine by Linear Poly (Ethylene …
Dec 6, 2006 · Linear poly (ethylene glycol) (PEG) is able to complex with neutral molecular Iodine in the solution state and in solid state, to produce I − 3 ions detectable by conventional spectroscopy and by photoacoustic spectroscopy (PAS).
Potassium iodide–polyethylene glycol catalyzed cycloaddition reaction ...
In this work, carbonated fatty acid methyl esters have been successfully prepared in 99% yield by cycloaddition of CO 2 with bio-based epoxidized methyl soyates. This was accomplished with a simple and cheap catalyst system of polyethylene glycol 400 (PEG-400) and potassium iodide (KI) under solvent-free conditions.
The “New Polyethylene Glycol Dilemma”: Polyethylene Glycol …
Jun 1, 2015 · The dependency of mAb1 crystallization and aggregate formation on peroxide and formaldehyde was ultimately confirmed by addition of both compounds to extensively purified PEG. Obviously, both impurities are required to initiate crystallization. A complex interaction of both compounds can be assumed.
