Ultrafast Lasers Offer 3-D Micropatterning of Biocompatible Silk Hydrogels

MEDFORD/SOMERVILLE, Mass. (September 23, 2015) -- Tufts University biomedical engineers are using low-energy, ultrafast laser technology to make high-resolution, 3-D structures in silk protein hydrogels. The laser-based micropatterning represents a new approach to customized engineering of tissue and biomedical implants.

The work is reported in a paper in PNAS Early Edition published September 15 online before print: "Laser-based three-dimensional multiscale micropatterning of biocompatible hydrogels for customized tissue engineering scaffolds."
