Copper Metal Organic Polyhedron (Cu-MOP) Hydrogel as Responsive Cytoprotective Shell for Living Cell Encapsulation.

Single-cells coated with functional shells to protect them from external harsh condition have great potential applications in many fields such as tissue engineering, cell-based devices, cell biology, and so on. Herein, copper metal organic polyhedron (Cu-MOP) hydrogel has been applied as a soft shell for cell protection under both physical and chemical stimulations. Compared with a previous strategy, this MOP-Gel shell not only possesses more satisfied protection effect but also could be prepared and removed facilely without any damage to the encapsulated cells.
