Engineering Microneedle Patches for Improved Penetration: Analysis, Skin Models and Factors Affecting Needle Insertion

Nano-Micro Letters, Journal Year: 2021, Volume and Issue: 13(1)

Published: March 16, 2021

Abstract Transdermal microneedle (MN) patches are a promising tool used to transport wide variety of active compounds into the skin. To serve as substitute for common hypodermic needles, MNs must pierce human stratum corneum (~ 10 20 µm), without rupturing or bending during penetration. This ensures that cargo is released at predetermined place and time. Therefore, ability MN sufficiently skin crucial requirement. In current review, pain signal its management application typical needles presented compared. followed by discussion on mechanical analysis models insertion tests before clinical practice. Factors affect (e.g., geometry, material composition cross-linking MNs), along with recent advancements in developed strategies responsive 3D printed biomimetic using two-photon lithography) improve penetration highlighted provide backdrop future research.
