UNH Researchers Create New Design That Could Lead to Improved Drug Delivery

Inspired by a color changing mechanism found in cephalopods such as squid, cuttlefish and octopus, researchers at UNH have designed a unique sequential cell-opening mechanism that has many potential applications from drug delivery to color altering camouflage materials. Yunyao Jiang, a doctoral candidate, worked with Yaning Li, assistant professor of mechanical engineering, to create and test the new concept.

“What makes this unique is that if each cell is assigned a different color, you could alter the sequential opening mechanism to create a material that might be dark green when the first cell opened and then change to bright yellow when the second one opened after it. This concept could also be used for particle release, such as two different medicines being released sequentially through a bandage to help address medical issues like wound swelling.”

This work was supported by a NSF/CAREER award to Dr. Li to explore the mechanics of auxetic chiral composite materials via innovative design and 3D printing.
