Shajna Shajahan*, Reshmi Krishna and Shehbas Ahammed

ABSTRACT

Global biomedical science has recently made significant strides with the development of microneedle (MN) technology. MN-based drug delivery has the potential to solve the current constraints of drug delivery, including poor biodistribution, low bioavailability, insufficient skin penetration, and poor absorption. Nanotechnology used a variety of natural and synthetic materials and their combinations to create microneedles (MNs) with significantly altered fabrication procedures and new design. Nowadays, because of its many uses and wide range of applications, MNs technology has become more and more well-known in medication delivery and biomedical research around the globe. The types, fabrication processes, composition, characterization, applications, and latest developments of MN are all covered in general in this review.

Keywords: Microneedle drug delivery, Stratum corneum, biodegradable polymer.
