The Minimum Inhibitory Concentration (MIC) and Minimal Bactericidal Concentration (MBC) Values of Different Nanomaterials Against the Two Tested Bacterial Strains
| Bacterial Strains | MICs (μg/mL) | MBCs (μg/mL) | MBCs/MICs | |||||
|---|---|---|---|---|---|---|---|---|
| GO | CuNPs | GO-Cu | GO | CuNPs | GO-Cu | CuNPs | GO-Cu | |
| MSSA, ATCC25923 | >512 | 32 | 8* | >1024 | 256 | 16* | 8 | 2 |
| MSSE, ATCC35984 | >512 | 24 | 4* | >1024 | 128 | 8* | 5.33 | 2 |
Note: *The antimicrobial efficacy of the nanocomposites was significantly improved after the combination of GO and CuNPs (p<0.01).
Abbreviations: CuNPs, copper nanoparticles; GO, graphene oxide; MSSA, methicillin-susceptible Staphylococcus aureus; MSSE, methicillin-susceptible Staphylococcus epidermidis.
