The Nanopatch has the potential to improve global health.
Mark Kendall was on his way to becoming a rocket scientist. Then he turned his talents to medical science and, using his knowledge of fluid mechanics, invented a method to deliver vaccine via a patch applied to the skin. His Nanopatch
has the potential to spare the lives of the 17 million people who die of infectious diseases every year.<br><br>The Nanopatch can immunize people against infectious disease more safely and more effectively than the traditional
needle or sugar cube. Thousands of invisibly small projections deliver vaccine directly to the area just under the skin’s surface, where the immune response is strongest, meaning much smaller doses are needed.<br><br>With
no refrigeration required for the vaccine, which is dry-coated on to the patch, the delivery process is easier and far cheaper, particularly in the developing world where electricity can be unstable. Administering the dose is simpler
too: a small applicator is used to propel the patch onto the skin and the patient is likely to feel only a small flick, a vast improvement from a needle. The patch is currently in clinical trials with the World Health Organization,
using the polio vaccine.
