Minimal Inhibitory Concentrations (MIC) as a function of the number of times bacteria have been serially passaged in presence of increasing concentrations of gentamicin or gentamicin-derived carbon quantum dots. Carbon quantum dots synthesized by calcination at different temperatures, T (sub-script), from gentamicin (GENT), induce less resistance of (A) a Gram-positive S. aureus and (B) a Gram-negative E. coli strain than gentamicin used as a carbon source.
