Controlled Aloin Release from Crosslinked Polyacrylamide Hydrogels: Effects of Mesh Size, Electric Field Strength and a Conductive Polymer
The aim of this paper is to investigate the effects of hydrogel mesh size, a conductive polymer, and electric field strength on controlled drug delivery phenomena using drug-loaded polyacrylamide hydrogels prepared at various crosslinking ratios both with and without a conductive polymer system. Poly(p-phenylene vinylene), PPV, as the model conductive polymer, was used to study its ability to c...
متن کاملElectrically controlled Aloin from poly(p-phenylene vinylene)/polyacrylamide hydrogel system
The apparent diffusion coefficients, Dapp, and the release mechanisms of Aloin-doped poly(phenylene vinylene)/polyacrylamide hydrogels, Aloin-doped PPV/PAAM, were investigated. In the absence of an electric field (passive release), the diffusion of Aloin from the SA-doped PPV/PAAM hydrogel is delayed in the first 36 hr due to the ionic interaction between the anionic drug and PPV. Beyond this p...
متن کاملPreparation of DNA-crosslinked polyacrylamide hydrogels.
Mechanobiology is an emerging scientific area that addresses the critical role of physical cues in directing cell morphology and function. For example, the effect of tissue elasticity on cell function is a major area of mechanobiology research because tissue stiffness modulates with disease, development, and injury. Static tissue-mimicking materials, or materials that cannot alter stiffness onc...

متن کاملRelease of theophylline from polymer blend hydrogels.
Polymer blending is a simple yet attractive method to obtain combined physical and mechanical properties of polymers. In this paper, three types of blend hydrogels were prepared, each by physically blending two different natural polymers, and a model drug, theophylline (TPH), was immobilized into these hydrogels for the studies of drug release. The release profiles of TPH from various types of ...
