Micro-Needle Patch (2013). The microneedle prototype is a collection of dozens of tiny needles that are lined up on a small patch. The needles are so tiny that each one is measured in micrometers and is as thin as a human hair. Dr Mark Prausnitz is a professor in the Georgia Tech School of Chemical and Biomolecular Engineering, and co-developer of the microneedle. He believes that, “A major advantage of the microneedle patch would be the ease of delivery.” Rather than the injection coming in a vial that must be drawn up by needle and syringe for injection, the microneedle patches come with the injection encapsulated within the dissolvable microneedles and are simply placed on the skin. It’s much like putting on a Band Aid, and the pain that comes with current subcutaneous injections is bypassed. The polymer microneedles then dissolve between layers of the skin, effectively delivering the injection.
