Purdue Scientists Developing Surgical Adhesive As Alternative To Stitches

Scientists at Purdue University are developing an adhesive that could serve as an alternative for stitches following surgery. The product is designed to be less invasive for patients.

Julie Liu is an assistant professor of chemical engineering at Purdue and is working on the team developing the adhesive. She says the aim is to create an adhesive that can stick not only to itself, but also to soft tissue. She says it’s crucial the adhesive can do so in a damp environment – like inside the human body.

“It could be a material that might be able to be used internally, and that’s actually where there are very few options,” Liu says.

Liu says the adhesive is still in development, and isn’t available for use in hospitals. The team presented a proof of concept paper, but still needs to run the adhesive through some tests.

Liu says they’re hoping the adhesive could replace stitches in the future. But she says there are a number of variables to consider.

“We’d have to test it in an animal, for instance; is that going to work?” Liu says. “It also depends which tissue we’re talking about. Some tissues might undergo more stresses, so it might get stretched more.”

The research team is currently working to patent the technology.
