In this work xanthan chains were crosslinked by esterification reaction at 165° C either in the
absence or in the presence of citric acid. Higher crosslinking density was obtained using …

Polyelectrolyte complexes (PECs) offer enormous material tunability and desirable
functionalities, and consequently have found broad utility in biomedical and material …

Particularly, chitosan (Cs) loaded with drug cannot pass through the colonic region, often
leading in the bursting drug release in the stomach due to its solubility in gastric contents …

Factors controlling the time-dependent mechanical properties of interpenetrating network
(IPN) hydrogel materials are not well understood. In this study, alginate-polyacrylamide IPN …

The main goal of enzyme immobilization is the re-use of enzymes for many reaction cycles
and extended periods of time. Many novel strategies have been developed during the past …

In this work, zinc oxide nanoparticles were synthesized in-situ within the gum acacia/poly
(acrylate) hydrogel network using hydrothermal approach. The synthesized zinc oxide …

To gain insight into the fundamental processes determining the motion of macromolecules in
polymeric matrices, the dynamical hindrance of polymeric dextran molecules diffusing as …

Hydrogels, and in particular microgels, are playing an increasingly important role in a
diverse range of applications due to their hydrophilic, biocompatible, and highly flexible …

Abstract pH-responsive membranes prepared by treating chitosan (Ch) with glutaraldehyde
(GA) or with GA and sulfuric acid (SA) were studied. The structure and properties of the …

Polyacrylamide hydrogels are widely used in biomedical applications due to their tunable
mechanical properties and charge neutrality. Our recent tribological investigations of …
