<br>
*Microneedles were first developed as a method for transdermal drug delivery . The microneedles
are long enough to penetrate the stratum corneum, which often acts as the primary barrier
potentially offering a painless method for drug delivery.
*The microneedles can be divided into "In-Plane" and "Out of plane" microneedle based o fabrication methods and as "Hollow" and "Solid" Microneedles based on their physical aspects.
