    Feb 04, 2005 · Abstract. Novel polymer core–shell nanoparticles that exhibited a pH-dependent lower critical solution temperature (LCST) have been synthesized. The nanoparticles displayed stable structure in a nominal physiological environment but deformed and precipitated in an acidic environment, thereby releasing the enclosed drug molecules (see Figure).
