WebMay 24, 2024 · Oxygen plasma is widely used for enhancing the wettability of numerous polymers, including polyethylene terephthalate (PET). The treatment with plasma containing oxygen will cause surface functionalization with polar functional groups, which will, in turn, improve the wettability. However, the exact mechanisms leading to the hydrophilic or … WebMay 27, 2024 · In particular, stimuli-responsive triblock terpolymers of the ABC type containing two different stimuli-responsive blocks and a third one that is a non-responsive hydrophobic or hydrophilic block have gained increased interest on account of their unique macromolecular architecture and fascinating aqueous solution properties, as well as of …
Smart Polymeric Micelles for Anticancer Hydrophobic Drugs
WebAug 24, 2016 · 1. Introduction. A hydrogel is a three-dimensional (3D) network of hydrophilic polymers that can swell in water and hold a large amount of water while maintaining the structure due to chemical or physical cross-linking of individual polymer chains. Hydrogels were first reported by Wichterle and Lím (1960) [ 1 ]. WebMay 22, 2024 · The presence of hydrophilic polymer brushes on MIP improved its surface hydrophilicity and significantly reduced their hydrophobic interactions with template molecules in pure aqueous media. In detection process, the acoustic delay-line is confederative to a microfluidic chip and inserted in an oscillation loop. porter wisconsin
Smart Polymeric Micelles for Anticancer Hydrophobic Drugs
WebJun 13, 2024 · In addition, hydrophobic moieties of PNIPAAm networks may be covered with water molecules by their adsorption onto the polymer chains and the networks may become more hydrophilic. WebDec 1, 2003 · Smart polymers are either reversibly soluble-insoluble (SIS) in aqueous media or crosslinked in the form of hydrogels. Specifically, hydrogels are networks of hydrophilic polymers that expand or swell by taking up “from 10%–20% up to thousands of times their dry weight in water” [1]. Physical hydrogels are held together with noncovalent ... WebMar 13, 2024 · In prodrugs with large hydrophobic segments, the hydrophobic drugs are usually located in the hydrophobic core of micelles and nanoparticles, which limits the access to the water, hence lowering significantly the hydrolysis rate. Finally, self-immolative polymers are also an intriguing new class of materials. porter yoshida flying ace belt bag
