Developed a patch with microneedles replacing a syringe

The vast majority of people have a negative attitude towards the injection procedure, since it is almost always associated with pain. A group of researchers at the Georgia Institute of Technology and Emory Medical University, led by Professor Nadine Rowfall, have developed an unusual patch, the surface of which is covered with plastic microneedles containing a medical preparation (vaccine).

Now, to make an injection, it is enough to apply a patch containing an array of needles to the skin. Once inside it, the needles quickly dissolve and the drug enters the bloodstream. The procedure is absolutely painless. Other advantages of the new technology are the absence of the need to store the vaccine in the refrigerator during transport and the safety of the already used patch.

In clinical trials, a plaster was used to inject flu vaccines. If successful, it could be used for other injections such as measles, rubella, polio vaccines and as a nicotine patch.
