In this paper it is shown that when a thermosensitive hydrogel based on poly(N-isopropylacrylamide)-poly(ethylene glycol)-poly(N-isopropylacrylamide) (pNIPAm-PEG-pNIPAm) was transferred into water, flower-like micelles were continuously released as long as the medium was regularly refreshed. On the other hand, if the medium

Thermo-sensitive poly(N-isopropyl acrylamide-co-vinyl pyrrolidone)/chitosan [P(NIPAM-co-NVP)/CS] semi-IPN hydrogels with improved loading capacity and sustained release for anionic drugs NAP were prepared by free-radical polymerization. The LCST of hydrogels was adjusted to the vicinity of body temperature by introducing hydrophilic NVP. The
