Abstract The Aedes aegypti mosquito is generally associated with arboviruses that cause yellow fever, dengue, zika and chikungunya. most efficient way to control their populations through application in breeding sites of highly toxic insecticides can also impact non‐target organisms generate resistant populations.

Diabetic wound healing presents a significant medical challenge and requires multistep interventions due to comprehensive environments, such as hyperglycemia, bacterial infection, impaired angiogenesis. However, current are complicated need on-demand sequential release synergy of multicomponents. Herein, H2S-releasing cascade nanozyme (FeS@Au), which is composed ultrasmall gold nanocluster (AuNC) loaded on ferrous sulfide nanoparticle (FeSNP), developed single component regulate glucose level, eliminate promote angiogenesis, achieving for diabetic treatment. The oxidase-like activity AuNC catalyzes into gluconic acid H2O2, not only lowers the local level but also decreases pH increases H2O2 boost peroxidase-like FeSNP generate abundant hydroxyl radical (reactive oxygen species, ROS), inducing ferroptosis-like death in drug-resistant bacteria. Additionally, H2S acidified environment upregulate hypoxia-inducible factor-1 enhance vascularization through upregulating expression vascular endothelial growth factor (VEGF) other angiogenesis-related genes, reducing damage cells caused by excessive ROS produced nanozyme. In full-thickness MRSA-infected rat model, FeS@Au significantly eliminates bacteria, enhances promotes collagen deposition, accelerates healing. This work with H2S-release interventions, providing versatile strategy extensive tissue diabetes.
