Dynamically cell separating thermo-functional biointerfaces with densely packed polymer brushes

Thermo-responsive polymer brush grafted glass surfaces with various brush lengths were prepared through surface-initiated ATRP as cell separating intelligent biointerfaces. A precisely designed PIPAAm brush is able to separate cells by the utilization of different detachment properties of cells from the surfaces.
