A temperature-and pH-responsive drug delivery system was studied by using interpenetrating polymer network (IPN) hydrogels constructed with poly(acrylic acid) (PAAc) and poly(vinyl alcohol) (PVA). The release of indomethacin incorporated into these hydrogels showed pulsatile patterns in response to
## Abstract Chitosan hydrogels have been investigated as potential vehicles for targeted drug delivery. The gels were permanently crosslinked with conventional crosslinking agent, glutaraldehyde and the naturally occurring nonβtoxic crosslinking agent genipin in both the monomer and polymerised sta
