A new body tissue sealing technique being developed by Fulton Schools Professor Kaushal Rege’s research team uses a laser to heat up gold nanorods to gently melt silk fibers. Those fibers then fuse with collagen — a protein within the body’s various connective tissues — to bond tissues and aid in healing of wounds and incisions, while also possibly preventing infections. The method can be applied to reinforcing the use of stitches to seal tissues or to potentially provide a resilient alternative to conventional stitching. Read more.
