Title: Solute Partitioning and Diffusion in Hydrogels: Fundamentals of Drug and Comfort-Agent Delivery
Abstract:
Hydrogels are biocompatible and, therefore, extensively applied, for example, in pharmaceutics, biomedicine, tissue engineering, and artificial organ scaffolds. Hydrogels also have application in a wide variety of bioseparation and biosensing processes. We focus specifically on hydroxyethyl-methacrylate (HEMA) /methacrylic acid (MAA) copolymer gels used in soft contact lenses to deliver drugs and comfort/wetting agents to the eye. In all applications, it is important to understand how aqueous solutes of varying size, molecular weight, charge, hydrophobicity, and configuration partition into and out of hydrogels which themselves are of differing water content, crosslink density (i.e., mesh size) and matrix charge density.
