Engineered Bio‐Heterojunction with Infection‐Primed H₂S Liberation for Boosted Angiogenesis and Infectious Cutaneous Regeneration (Small 45/2023)

Tissue Regeneration In article number 2304324, Yi Deng, Kunneng Liang, and co-workers report the innovative P-N bio-heterojunction (bio-HJ) material with infection-primed H2S liberation. In this system, fast sterilization is achieved through the self-built-in electric field intensified photodynamics therapy and photothermal therapy. Meanwhile, H2S generated in situ from bio-HJs accelerates revascularization through up-regulating hypoxia-inducible factor-1 (HIF-1) pathway in infected wounds, which significantly boosts healing rates of full-thickness wounds in vivo.
