Abstract
A cell culture support comprising a substrate, and a dual stimuli responsive block copolymer immobilized on the substrate, wherein the dual stimuli responsive block copolymer is both thermoresponsive and pH responsive. A method of culturing cells comprising the cell culture support having a dual stimuli responsive copolymer immobilized on a substrate, wherein the dual stimuli responsive copolymer is thermoresponsive and pH responsive; and growing the cells on the cell culture support. By lowering the temperature, cells are released from the cell culture support.
