A Hollow Microneedle Equipped with a Micropillar for Improved Needle Insertion and Injection of Drug Solution

ConclusionIn the present study, hMN1300S showed effective solution delivery into an intradermal site. In particular, a micropillar can be effective for depth control of the injected solution as well as preventing contact between the hMN pedestal and the deformed membrane. The obtained results will help in the design and development of hMNs that ensure successful injection of an administered drug.
