research Smart Stimuli-Responsive Microneedle Platforms for Precision Androgenetic Alopecia Therapy: Materials Strategy and Therapeutic Perspectives
Stimuli-responsive microneedles (SR-MNs) represent a significant advancement in the treatment of androgenetic alopecia (AGA) by offering precise, minimally invasive drug delivery. These microneedles utilize both exogenous triggers, such as optical and thermal stimuli, and endogenous cues, like reactive oxygen species and enzymatic activity, to achieve controlled therapeutic release. This approach addresses the limitations of conventional AGA treatments by enhancing drug delivery to hair follicles while minimizing systemic side effects. The successful clinical application of SR-MNs depends on the development of biocompatible materials and scalable manufacturing processes.
