Ultrasound-Activated FeSnO(OH)5/Cu2S Heterojunction Microneedles Coordinate Redox Catalysis and Metal-Ion Dyshomeostasis for Localized Tumor Therapy

An ultrasound-activated microneedle patch (FCSP-MN) was developed for localized tumor therapy by integrating FeSnO(OH)5/Cu2S heterojunction nanoparticles (FCS) and phloretin into pH-responsive poly(acrylic acid)/poly(vinylpyrrolidone) microneedle tips. Heterojunction formation pr...
