Soft self-supported cohesive films were formed by self-assembly of pH- and thermo-responsive P(MEO2MA-co-OEGMA-co-MAA) microgels without any preparation and/or post-treatments. Linear non-linear mechanical properties those characterized respectively dynamic measurements at low strain uniaxial extensional tests high deformation. A relationship between the microstructure strength microgel-based w...

Hydrogels based on poly(acrylic acid) and gelatin crosslinked with N,N'-methylene bisacrylamide (0.5mol%) and glutaraldehyde (4%), respectively, forming an interpenetrating network were employed as matrices, for studying the loading and release of gentamicin sulphate. The release kinetics of gentamicin sulphate was evaluated in water (pH approximately 5.8), phosphate buffer (pH 7.4) and citrate...

Currently used in vitro models for estimating liver metabolism do not take into account the physiologic structure and blood circulation process of liver tissue. The Bio-PK metabolic system was established as an alternative approach to determine the in vitro intrinsic clearance of the model drug tolbutamide. The system contained a peristaltic pump, recirculating pipeline, reaction chamber, and r...

• Anion species-triggered antibody separation under optimized constant temperature. species-responsive retention of antibodies by thermo-resopnsive polymer column. Successful therapeutic monoclonal from contaminants. Although the field drugs has grown larger, production still faces several challenges. Effective purification is required, but conventional method for cost intensive and often cause...

Bioadhesive polymeric hydrogels capable of firm adhesion to various biological tissues have acquired considerable attention due their significance in medicine and dentistry. Thus far many types bioadhesive been investigated using different polymers such as polyacrylates, poly(ethylene glycol)s, the derivatives polysaccharides proteins, while less has paid polyamphoteric properties cross-linked ...

Purification of dye-laden water endures to be immensely challenging owing the occurrence highly persistent and non-biodegrade dyes, which pose a potential threat humans, flora, fauna, environment. The environmental problem was addressed by facile fabrication poly [(2-acrylamido-2-methyl-1-propane sulfonic acid-co-acrylamide-co-acrylic acid)] hydrogels cross-linked via sodium borate (SB), graphe...

Supramolecular cross-linked porous lignin based poly (acrylic acid) [LBPAA] was lab-synthesized by copolymerizing lignin grafted N, N'-methylene-bisacrylamide (LM) and acrylic acid. LBPAA successfully acted as a water retention agent with salt resistance and biodegradation for agricultural applications. Lignin was found to improve its swelling behaviors with higher water retention, fast swellin...

Abstract The description of gel swelling by Flory and Rehner using the original Flory–Huggins interaction parameter for polymer–solvent cannot be applied to most smart microgels. Here, we compare descriptions curves such microgels series expansions $$\chi$$ ? with results Hill-like equation . We study N -isop...
