• modified AgNPs were the most effective, showing minimum inhibitory concentration (MIC) values in a restricted range of 1.0–3.7 µg/mL. An explanation is proposed for this result based on the increased surface reactivity of the metal surface due to the presence of positively charged active sites. Keywords

The lowest minimum inhibitory concentration (MIC) values for Gram-positive as well as Gram-negative bacteria were correlated to the smallest nanoparticles used (5 nm and 7 nm) in different studies [28][29][30].
