Abstract

Interactions between diuretics and a recently synthesized temperature-responsive neutral copolymer, poly(N-isopropyl acrylamide) (PNIPA) grafted with poly(ethyleneoxide) (PEO) (PNIPA-g-PEO) were investigated by capillary electrophoresis and dynamic light scattering (DLS). At ambient temperatures, the copolymer takes an open, random coil conformation, but above the lower critical solution temperature (LCST), the polymer shrinks and forms large, stable aggregates. Among the diuretics studied, hydrochlorothiazide was detected to bind to PNIPA-g-PEO.
