Professors’ Nguyen, Gracias and Schulman work on active hydrogels featured in ACS’ Chemical and Engineering News

Harnessing the power of shape-shifting polymers

” …Research teams such as those of David Gracias and Thao (Vicky) Nguyen at Johns Hopkins University have already shown the potential utility of pNIPAM-based grippers. The points of the star-shaped devices curl inward like a claw when activated. “Let’s say you want to capture a biopsy of a tumor,” Nguyen says. “You could have patients swallow these grippers and guide them to the right tumor so that they can actually grip the tumor and pull some cells off….”
