Boosting Medicine Delivery: Mixing Microneedles with Biodegradable Particles
Scientists sought to improve the way medicine, like methotrexate, passes through human skin. They used tiny needles called Dr. Pen microneedles and tiny, biodegradable beads called poly(d, l-lactide-co-glycolide) acid microparticles. These beads came in eight different forms. The team studied the be
