This research develops a new method for high-resolution 3D printing of metals such as copper. Instead of laser melting, ultraviolet light forms hydrogel structures that are chemically transformed into metal. The technique enables finer features, reduced waste, and fabrication of advanced materials for applications including batteries, structural engineering, and manufacturing.

Corneal scarring causes widespread vision loss and is poorly treated by transplantation alone. This research develops a bioengineered corneal glue that both seals and heals wounds by promoting cell infiltration and reducing fibrosis. The approach enables scar-free healing, lowers transplant rejection risk, and offers a regenerative alternative to sutures and conventional sealants.
