research Hafnium Oxide Nanostructure-IntegratedSilk FibroinMicroneedles Reshape Cutaneous Melanocyte Microenvironment for VitiligoTherapy
This study developed a silk fibroin/poly(vinyl alcohol) microneedle loaded with α-aminoxyacetate and HfO2 nanoparticles for vitiligo treatment, which protected against ROS damage and modulated immune responses, leading to improved melanogenesis and skin repigmentation.
