Graphene oxide/poly(vinyl alcohol) (GO/PVA) composite hydrogel was prepared and utilized for selective drug release at physiological pH.

thermoplastic starch (tps) materials present several advantages to the plastic industry andwhen blended with other materials they can exhibit improved mechanical and moisturesensitivity properties compared to pure tps materials. further investigations on tps: pvablends are of particular interest due to their excellent compatibility and improved properties suchas tensile strength, elongation, to...

Relative humidity monitorization is of extreme importance on scientific and industrial applications, fiber optics-based sensors may provide solutions where other types have limitations. In this work, optics’ were fabricated by combining Long-Period Fiber Gratings with three different humidity-responding polymers, namely Poly(vinyl alcohol), Poly(ethylene glycol) Hydromed™ D4. The performance th...

The present review aims to give a closer look of hydrogels based on chitosan and poly (vinyl alcohol) and to discuss their potential biomedical applications in drug delivery system. Various investigations based on chitosan/poly (vinyl alcohol) carried out recently by researchers have been reported in this review. Moreover different chemical and physical crosslinking methods used for hydrogels f...

Poly(vinyl alcohol) hydrogels have a significant range of mechanical properties based on compositional and processing parameters. Biodegradable hydrogels based on Poly(vinyl alcohol) were prepared for controlled drug delivery of bovine serum albumin. These hydrogels were synthesized by a crosslinking technique using glutaraldehyde as a crosslinker. Hydrogels containing drug were prepared by dir...

A novel two-compartment model for drug release was formulated. The general fractional derivatives of a specific type and distributed order were used in the formulation. Earlier models pharmacokinetics with follow as special cases proposed here. As first application, we this to study gentamicin from poly(vinyl alcohol)/chitosan/gentamicin (PVA/CHI/Gent) hydrogel aimed at wound dressing medical t...

Antifreeze (glyco) proteins are produced by many cold-acclimatized species to enable them to survive subzero temperatures. These proteins have multiple macroscopic effects on ice crystal growth which makes them appealing for low-temperature applications-from cellular cryopreservation to food storage. Poly(vinyl alcohol) has remarkable ice recrystallization inhibition activity, but its mode of a...
