Abstract

In the present research, thermoresponsive interfaces grafted with high-density poly(N-isopropylacrylamide) (PIPAAm) are prepared by surface-initiated atom transfer radical polymerization (ATRP) on poly(p-chloromethylstyrene)-cast polystyrene surfaces. Surface characterization revealed that thermoresponsive polymers were covalently grafted onto the polystyrene surfaces. Moreover, we investigated influence of thermoresponsive surface characteristics on adhesion/detachment behavior of cultured cells. Results suggest that control of the amount of grafted PIPAAm, and also the differences in its PIPAAm constructed structure influence cell adhesion/detachment control.
