pH Sensitive Hydrogel Based Acrylic Acid for Controlled Drug Release

Hydrogels, due to their unique potentials such as high-water content and hydrophilicity are interest for the controlled release of drug molecules. The present study aims to create a controlled-release system through the preparation and characterization of hydrogels based on pH-sensitive polymers such as poly (acrylic acid). Poly (acrylic acid), p(AA), hydrogel has been synthesized by radical po...

Preparation and pH-Sensitive Release Behavior of Alginate/Activated Carbon Composite Magnetic Hydrogels

The alginate-based hydrogel was prepared as a pH-sensitive drug delivery system. To enhance the drug loading capacity, activated carbon was introduced as a drug absorbent. The iron oxide was incorporated into the alginate matrix for the magnetic transferring to the target organ. The activated carbon and iron-oxide were dispersed uniformly in the alginate hydrogel. The drug release from the algi...

Investigation of Swelling Behavior and Mechanical Properties of a pH-Sensitive Superporous Hydrogel Composite

   The objective of the present study is to develop and investigate the swelling behavior of pH-sensitive Superporous Hydrogel (SPH) and SPH composite (SPHC). A novel superporous hydrogel containing poly (methacrylic acid-co-acrylamide) was synthesized from methacrylic acid and acrylamide through the aqueous solution polymerization, using N,N-methylenebisacrylamide as a crosslinker and ammonium...

pH-Responsive Hydrogel with Controlled Swelling and Degradation Rate

A range of hydrogels were prepared by solution polymerization of methacrylic acid, poly(ethyleneglycol) methyl ether methacrylate (M.W. 475 g/mol) and poly(ethyleneglycol) dimethacrylate (as the cross-linking, M.W. 550 or 875 g/mol) in various proportions. The effects of methacrylic acid/ poly(ethyleneglycol) methyl ether methacylate concentration ratios as well as cross-linking concentration i...
