Abstract

In the present research, thermoresponsive polymer brush surfaces grafted with high-density poly(N-isopropylacrylamide) (PIPAAm) are prepared by surface-initiated atom transfer radical polymerization (ATRP) using poly(p-chloromethylstyrene) as an ATRP initiator. Thermoresponsive surface characteristics are analyzed for the surfaces prepared at different reaction times. We succeeded to adhere endodermis cells (ECs) onto PIPAAm brush surfaces at 37°C while these cells detached by incubation at 20°C. Grafted polymer architecture as well as the grafted amount of PIPAAm chains should have important influence on cell adhesion/detachment behavior.
