Effect of ZnO QDs on the growth of MB45. Cultures were setup with an initial cell number 9 × 106 cells in Luria broth amended with different concentration [solid rhombus (♦), Control 0.0 mg/L; open triangle (∆), A 200 mg/L; filled triangle (▲), B 400 mg/L; open rectangle (□), C 500 mg/L] of colloidal solution of ZnO QDs. Cultures were incubated at 37°C with constant shaking at 200 rpm under normal laboratory condition. Bars shows standard error.
