Redox‐Driven Host–Guest Interactions Allow the Controlled Release of Captured Cells on RGD‐Functionalized Surfaces

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 β‐CD/Fc redox‐switchable system.
