Dimethylaminoethyl Methacrylate

We investigate the coil-to-globule transition of poly(2-dimethylaminoethyl methacrylate) (PDMAEMA) in the aqueous solution through the lower critical solution temperature (LCST) by atomistic molecular dynamics (MD) simulations.

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.

An anthracene-functionalized thermosensitive block copolymer was synthesized, which formed micelles by heating its aqueous solution above the lower critical solution temperature (LCST). The micelles were subsequently crosslinked by UV illumination at 365 nm with a normal handheld UV lamp.

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.
