Abstract
Interpenetrating polymer network (IPN) hydrogels of chitosan with N-vinylpyrrolidinone (NVP) as well as its copolymer with 2 -hydroxyethyl met hacrylate (HEMA) were synthesised through the photoinitiator - free photopolymerisation technique. These hydrogels exhibited high swelling abilities and fast drug release rates. These tests also revealed that water diffusion into the hydrogels and drug release kinetics, with the exception of the ones with HEMA incorporated did not adhere to the Fickian model. Toxicity tests on human keratinocyte showed no evidence of these gels being toxic.
