Hydrogen Bond Acceptors and Additional Cationic Charges in Methylene Blue Derivatives: Photophysics and Antimicrobial Efficiency

Table 2

Overview of the phototoxic efficacy of the MB derivatives on S.  aureus and E. coli; the table shows only the photodynamic treatment with light (effects of dark toxicity can be found in the supporting information). Different concentrations of each photosensitizer were applied and toxic efficacy is described in steps of log₁₀-reduction; therefore “<3” means a reduction <3 log₁₀ steps (<99.9%).
