Carbohydrate Containing Cross-linked Hydrogels Used for the Removal of Water Soluble Cationic Dyes

Abstract

Gels are 3-dimensional (3-D) networks of polymer chains, where the monomers constituting the polymers are formed through covalent or non-covalent interactions. There are two types of polymer gels,hydrogels or organogels, respectively, dependent upon the solvent that solvates the polymer chains.1 Hydrogels have a variety of applications in tissue engineering, drug delivery, protein chromatography and enzyme recycling etc.2,3,4 This poster will report our investigation of the synthesis and characterization of a novel class of carbohydrate-based gel networks. The nature of the resultant gels can tuned from organogels to hydrogel by a simple deprotection approach. The hydrogels can absorb a model drug (the dye Rhodamine-B, methylene blue) and release it at certain time intervals. The absorption and release of the dye was measured by UV-Vis spectroscopy. The interior morphology of the organogels and hydrogels was studied by field emission scanning electron microscopy (FE-SEM)
