WebApr 13, 2024 · Poly(N-isopropylacrylamide) is a stimuli-responsive polymer that exhibits a reversible phase transition in aqueous solution (sol-gel) at 32–34 °C [46,47], called lower critical solution temperature (LCST). The three nanoprecipitation temperatures were chosen to act below the LCST (30 °C), near the LCST (34 °C), and above the LCST (38 °C).
