Researchers from Rutgers University, New Jersey, have created bioinspired, programmable microneedles that enhance tissue adhesion using Projection micro-stereolithography (PµSL). Influenced by the microhooks of parasites, barbed stingers of honeybees, and quills of porcupines, 4D printed backward-facing barbs were fabricated and designed to deform horizontally to be minimally invasive upon tissue contact.
