Microneedles: Selected Applications for Pediatrics

Microneedles are a pediatric-friendly drug delivery system that has attracted many novel research endeavors. The fact that it creates a tiny cavity in the epidermis, which can allow peptides, proteins, nucleotides, and other large-sized molecules to penetrate the skin barrier, is very advantageous for transdermal delivery. In this review article, we shed light on several pediatric applications of microneedles, such as the delivery of proteins, vaccines, and diagnostics. We believe the advantages of microneedles will continue to expand and be applied to other sites in the body.
