Researchers at HKUST have created CarGAP, a chemo‑optogenetic system that couples vitamin B₁₂ binding with green‑light activation to toggle gap junctions on and off. In the dark, vitamin B₁₂ induces oligomerization of a bacterial CarHC domain, physically blocking connexin or innexin channels; a brief 570 nm light pulse disassembles the block, restoring communication. The team demonstrated precise control of fluorescent dyes, immune messenger 2′3′‑cGAMP, and cAMP signaling in cultured mammalian cells and in live fruit‑fly ovaries. This reversible, biocompatible approach offers a new way to probe cellular coordination in development, immunity and neurobiology.
Researchers demonstrated a green route to synthesize silver nanoparticles using aqueous extracts of dried mushrooms, which serve simultaneously as reducing and stabilizing agents.
