The grafted hydrogels of N-isopropylacrylamide (IPAAm) with 2-hydroxyethylacrylate (HEA) was prepared in an aqueous solution using ammonium persulfate (APS) and N,N,N’,N’-tetramethylethylene diamine (TEMED) as an accelerator. Lower critical solution temperature (LCST) and swelling ratios were measured as a function of temperature. The properties of the hydrogels contained pyrenyl probe in water were investigated by fluorescence spectroscopy.

Release Profiles

Thermo-responsive hydrogel can change their swelling behavior and drug release characteristics in response to environmental temperature [1–5]. Poly(N-isopropylacrylamide) (PNIPA) hydrogel undergoes a phase transition when the temperatue is lower than a lower critical solution temperature (LCST) of ∼32°C in aqueous solution [8], and drug release profiles in PNIPA hydrogel can be controlled by the alternation of their solution temperatures.
