Fast swelling highly porous superporous hydrogels (SPH) are synthesized through a method utilizing rapid solution polymerization of acrylic acid for development of gastric retention devices. The swelling property, mechanical strength and release profile o... see more

The aim of this present work is to use polyvinyl alcohol (PVA) – gelatin-based  hydrogel prepared by ?-rays irradiation with different gelatin concentrations ranging from 0.5 - 2 %w/v for immobilization of Metformin HCl (MH) at dose range of 0 - 30 m... see more

Over the past few decades, formation of polymer hydrogels complexes with metal ions, including transition ones, attracts the steady attention of researchers. The relevance of such study is due to the fact that the kinetics of swelling and contraction of h... see more

PVA/Na-CMC hydrogels were prepared from polyvinyl alcohol (PVA) and Na-CMC isolated from OPEFB. Maleic anhydrous (MA) was introduced as a crosslinking agent during the formation of the hydrogel process. The characterization of the PVA/Na-CMC hydrogels was... see more

The development of a wound dressing is necessary to accelerate wound closure, promote tissue growth, and reduce scar formation. Hydrogel can be used as an ideal wound dressing. There are many materials that can be used as ingredients in the manufacture of... see more

Objective: Several studies have used aloe vera hydrogel to enhance various tissues regeneration to reduce scar formation in wounds. This study aimed to prepare a hydrogel specified for the oral cavity and observe scar formation and healing of free gi... see more

The mechanism of formation of slightly crosslinked composite hydrogels based on natural agar-agar polysaccharide, synthetic polymers for medical purposes – poly-N-vinylpyrrolidone (PVP) and low-molecular plasticizers (polyethylene glycol PEG-400 and glyce... see more
