Transdermal Drug Delivery: Zn‐MOF Encapsulated Antibacterial and Degradable Microneedles Array for Promoting Wound Healing (Adv. Healthcare Mater. 12/2021)

In article number 2100056 by Yongan Wang, Yuan Luo, Yuanjin Zhao, and co-workers, a ZIF-8@MeHA microneedle (MN) array is fabricated by template molding method for wound healing. Such an MN patch has a good antibacterial effect by releasing Zn2+ to kill microbes. Meanwhile, the MeHA hydrogel is capable of promoting the regeneration of neonatal epithelial tissues through gradual degradation.
