Researchers have proved that "injection-free" vaccines are an effective tool in the fight against diseases. The team, based in King's College London and funded by the Bill & Melinda Gates Foundation, used dried sugar to create a microneedle array — a tiny disc that only lightly perforates the skin.
Dr. Klavinskis mentions that this new system may prove useful in delivering insulin.
Consider the possibilities! Of course, they will probably have to make the disc out of something other than sugar.
