abstract

today hydrogels are considered as the materials that are able to play important role in drug delivery systems. to design an effective hydrogel applicable network, mathematical modeling has a critical role. a successful drug delivery device relies not only on intelligent network design but also on accurate prior mathematical modeling of drug release profiles. in this study, the modeling of the inflation behavior of temperature-sensitive hydrogel has been done by providing a mathematical model according to the thermodynamics and kinetics of the temperature-sensitive gel and also considering the heat transfer into the hydrogels during the inflation. the proposed model has been investigated numerically. the comparison between numerical and experimental results shows perfectly success in integrating equations of inflation thermodynamics and kinetics for modeling the inflation behavior of temperature-sensitive hydrogels that provide a new step in the modeling of such systems.

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...

Controlled Release Drug Delivery from Hydrogels

The objective of this project is to introduce students to the concepts of diffusion, polymers and polymerization reactions, and enzyme mediated reactions by designing and testing a controlled release drug delivery system. These types of systems are also referred to as localized drug delivery because an implant that releases drugs is placed directly into diseased tissue. Here, we use Jell-O c ©a...

Antimicrobial Modified-Tragacanth Gum/Acrylic Acid Hydrogels for the Controlled Release of Quercetin

In this study, new antimicrobial hydrogels were prepared via reaction of functionalized-tragacanthgum (TG) biopolymer by quaternary ammonium functionalization of TG (QTG) with acrylic acid(AA). Characterization of the QTG hydrogels (QTG-AA) was carried out by FTIR,thermogravimetric analysis (TGA), and 1H NMR. Dynamic mechanical analysis, (DMA) wasconducted to characteriz...

Interpenetrating Network Hydrogels: Mechanical, Swelling and Controlled Drug Release Properties

The cell wall of most plant biomass from forest and agricultural resources consists of three major polymers, cellulose, hemicellulose, and lignin. Of these, hemicelluloses have gained increasing attention as sustainable raw materials. In this study, novel pH-sensitive semi-IPN hydrogels based on hemicelluloses and chitosan were prepared using glutaraldehyde as the crosslinking agent. The hemice...

Environment-sensitive hydrogels for drug delivery.

Environmentally sensitive hydrogels have enormous potential in various applications. Some environmental variables, such as low pH and elevated temperatures, are found in the body. For this reason, either pH-sensitive and/or temperature-sensitive hydrogels can be used for site-specific controlled drug delivery. Hydrogels that are responsive to specific molecules, such as glucose or antigens, can...
