research A lipid–polymer hybrid nanoparticle (LPN)-loaded dissolving microneedle patch for promoting hair regrowth by transdermal miR-218 delivery
This study demonstrated that a device combining hyaluronic acid-based dissolving microneedles and lipid polymer hybrid nanoparticles effectively delivered miR-218 to promote hair growth in a shaved mouse model, outperforming topical smear treatment without safety concerns.
