Thermoresponsive micropatterned substrates for single cell studies.

We describe the design of micropatterned surfaces for single cell studies, based on thermoresponsive polymer brushes.We RESTORE show that brushes made of poly(N-isopropylacrylamide) grafted at high surface density display excellent protein and cell anti-adhesive properties.Such brushes are readily patterned at the micron scale via deep UV photolithography.A proper choice of the adhesive pattern shapes, combined with the temperature-dependent swelling properties of PNIPAM, allow us to use the polymer brush as a microactuator which induces cell detachment when Gift Card the temperature is reduced below [Formula: see text]C.
