These biodegradable microneedles, each less than a millimeter tall, could be coated or embedded with vaccines and applied to the skin as a patch. The needles would penetrate the highly immunoactive outer layers of the skin but not the deeper layers containing nerves and blood vessels, making them painless, safe and potent.
Peter DeMuth explains how and why he captured this image of a microneedle array.
