Suction Cup for the Cheek: A Minimally Invasive Drug Delivery Solution

According to a recent Medgadget article, researchers at ETH Zurich in Switzerland have developed a suction cup-inspired device to deliver large drugs like peptides non-invasively into the bloodstream. The cup attaches to the inside of the cheek using a vacuum, stretching the tissue and making it more permeable to drugs. It also exposes the mucosal lining to a permeability enhancer, helping peptides cross the lining more effectively.
