Microneedle patches or Microarray patches are micron-scaled medical devices used to administer vaccines, drugs, and other therapeutic agents. [2] While microneedles were initially explored for transdermal drug delivery applications, their use has been extended for the intraocular, vaginal, transungual, cardiac, vascular, gastrointestinal, and ...

Prausnitz is best known as the founder of Microneedle drug delivery, having published the first paper on microneedle use for drug delivery in 1998, [10] conducted the first clinical trials of drug and vaccine delivery using microneedles, [11] founded seven companies based on the technologies.
It is a transdermal patch comprising glucose-sensitive microneedle-array loaded with insulin for blood glucose regulation. Once applied on the skin, the microneedles penetrate under the skin and can sense blood sugar levels. If glucose levels go up, it can promote the release of insulin, which is transported through the regional lymph and ...
A microneedle approach, which is still in stages of development, uses "pointed projections fabricated into arrays that can create vaccine delivery pathways through the skin". [ 140 ] An experimental needle-free [ 141 ] vaccine delivery system is undergoing animal testing.
