Microscale cell manipulation by using photodegradable hydrogel

In this work, we present a novel photocleavable crosslinker to form photodegradable hydrogel through one step reaction by mixing with biocompatible polymers containing amino moieties (amino-terminated tetra-arm poly(ethylene glycol) or gelatin). Our new photocleavable crosslinker can be utilized as potentially versatile and convenient material to prepare photodegradable hydrogels with amino terminated biocompatible polymers. We present a couple of cell manipulation technique using the photodegradable hydrogels prepared with our photocleavable crosslinker.
