Today’s Solutions: March 29, 2023

We recently shared a story about a high schooler who developed infection-detecting sutures. Today, we’ve got another suture solution, but this time, gel sheathed sutures that can deliver drugs and prevent infection. 

Developed by researchers at McGill University, the sutures, called tough gel sheathed (TGS) mimic human tendons and imitate the structure of soft connective tissues. Unlike conventional sutures, which are rough against already fragile tissue, TGS forms a slippery surface to reduce friction with surrounding tissues. 

Jianyu Li, an assistant professor in the mechanical engineering department who participated in the development says, “This technology provides a versatile tool for advanced wound management. We believe it could be used to deliver drugs, prevent infections, or even monitor wounds with near-infrared imaging.”
