IIT (BHU) team published green-light activated antibacterial compounds study

Scientists at IIT (BHU), Varanasi published a study in Communications Chemistry titled “Green-light-activated Os(II) metallophotoantibiotics for antibacterial therapy and infected wound healing.” The paper reports osmium-based compounds (Os1–Os3) that, when activated by green light, inhibited bacterial growth, disrupted biofilms, and accelerated healing of infected wounds in rat laboratory studies; Os1 reportedly achieved about 85% inhibition of biofilm formation in E. coli and Bacillus subtilis under green-light exposure.
