TEM images of A) E.coli and B) AE. C) Fluorescent images of AE, indicating successful TBP‐2 loading into these bacteria. λ _ex = 488 nm and λ _em = 600–700 nm. D) Absorption spectra of E.coli (in PBS), AE (in PBS), and TBP‐2 (1% DMSO fraction). E) TBP‐2 levels in different E.coli populations. F) TBP‐2‐mediated •OH generation with/without white laser (WL, 0.1 W cm⁻², 5 min) excitation via ESR. G) 9,10‐Anthracenediyl‐bis(methylene)‐dimalonic acid (ABDA) decomposition rates induced by ¹O₂ generation associated with the indicated formulations under WL excitation (0.1W cm⁻², 5 min, TBP‐2 was dissolved in 1% DMSO solution). H) TA decomposition rates induced by •OH generation associated with the indicated formulations under WL excitation (0.1W cm⁻², 5 min, TBP‐2 was dissolved in 1% DMSO solution). I) Assessment of the antibacterial effect of TBP‐2 on E. coli under different lighting conditions.
