Skin Patches Instead of Needles: Can Nanotechnology Vaccinate the World?

(The Conversation) –  Think of a device which is around postage stamp size and has thousands upon thousands of tiny spikes on its surface: this is a nanopatch. There are approximately 20,000 projections per square centimeter on each patch, each around 60 to 100 micrometres in length. One micrometre is one million times smaller than a metre, so the height of these tiny spikes is approximately the width of a human hair.
