Microneedles are a platform for transdermal drug delivery. The advantages of microneedles include the delivery of large molecules, painless and less invasive administration of the active pharmaceutical ingredient (API), ease of administration, and improved drug delivery including dose, delivery rate and efficacy. Microneedles are also effective for vaccine delivery due to the abundance of immune cells in the dermis.

The microneedle applicator set can be used with the microneedle templates to make and apply reproducible and high quality microneedle patches for a variety of therapeutics.
