(a) Graphical depiction of the bactericidal ability of C. limetta-synthesized green Fe2O3-NPs and (b) pictorial representation of the observed antibacterial results. The alphabets A, B, C, and D show serial dilutions corresponding to 40 mg/mL, 20 mg/mL, 10 mg/mL, and 5 mg/mL, respectively. The symbols “–” refer to the negative control, whereas “+” or “PC” symbolize the positive control, which was Levofloxacin. The assay was carried out three times (n = 3), and the values are presented as the means ± SDs.
