The design of the hypodermic needle has changed little since 1853, when French surgeon Charles Gabriel Pravaz first attached a hollow, skinpiercing cylinder to a syringe. today, medical-device designers are using micro-scale materials to make the needles shorter and thinner, which makes for less painful shots.
In a successful test of a prototype nanotech vaccine patch, Australian researchers at the University of Queensland used a patch smaller than a postage stamp to deliver vaccine through the skin without needles, and with just 1/100th of the vaccine normally required to evoke a protective immune response, according to Pharmacy News.
