    AnnotationWe report on antibacterial activity of NDs and GO as evaluated by bacterial colony counting. ND and GO were used in oxidized (O-ND, GO) or reduced (H-ND, rGO) forms. ND or GO are mixed in Mueller-Hinton (MH) broth with Escherichia coli at the concentration of 1 mg/ml. The resulting suspensions were cultivated for 5 and 24 h at 37°C in a shaker. After each period a sample of the suspension was spread on the MH agar and cultivated for 24 h at 37° C. The effect of nanomaterials on colony forming ability (CFA) of E. coli was evaluated compared to negative control sample. The most noticeable effect was that after 5 hours H-ND decreased the CFA of E. coli in the MH broth by 60% and GO by 50%. After 24 hours, H-ND decreased CFA by 50%. Other nanomaterials had no statistically significant antibacterial effect. Factors influencing ND and GO antibacterial activity against the E. coli and possibly against other bacteria are discussed.
