Fig. 36. Illustration of the operative mechanism of light-responsive antimicrobial multifunctional nanoplatform consisting of core/shell structured MSNs embedding carbon dots (C-dots) and rose bengal (RB), respectively, and loaded with ampicillin (AMP). Under green light irradiation the RB photosensitizer facilitates the production of singlet oxygen species (1O2) to achieve photodynamic therapy (PDT), which in combination with AMP release led to synergetic antibacterial effect.775 Adapted with permission from ref. 775.
