Redox-driven host-guest interactions allow the controlled release of captured cells on RGD-functionalized surfaces.

ABSTRACT

A quartz crystal microbalance technique with dissipation monitoring and a complementary optical microscopy technique were used for monitoring the capture and release of specific cells on a surface displaying a bifunctional molecular device, composed of a molecular scaffold endowed with the cell recognition property of an RGD ligand and a ß-CD/Fc redox-switchable system.
