Nanotechnology is a multidisciplinary branch that is gaining great relevance in recent years due to the production of nanomaterials and their versatile use, Core-shell Ag@SiO2 nanoparticles are gaining notoriety due to the nature of each of their compounds; Since, together, they have long-term antibacterial activity compared to other nanoparticles, this project was developed with the aim of determining the effect of different concentrations of Core-shell Ag@SiO2 nanoparticles on the growth of Escherichia coli and Staphylococcus aureus in vitro as well as determining the minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC), the antibacterial effect was performed using the modified Kirby Bauer technique with holes and the presence of inhibition halos was obtained as a result in the concentrations of 8.3 μg/mL, 6.23 μg/mL, 4.15 μg/mL and 2.08 μg/mL for Escherichia coli and at concentrations of 8.3 μg/mL, 6.23 μg/mL and 4, 15 μg/mL for Staphylococcus aureus the minimum inhibitory concentration (MIC) was performed using the microdilution technique and it was found that for Escherichia coli it was at a concentration of 1.25 μg/mL and Staphylococcus aureus at a concentration of 2.905 μg/mL with respect to the minimum bactericidal concentration (CMB) it was found that for Escherichia coli it was at the concentration of 1.66 μg/mL and for Staphylococcus aureus 3.35 μg/mL, to the results the statistical tests of Anova and Tukey were applied in which we showed that there was a difference between the applied treatments and between bacteria, resulting in Escherichia coli bacteria being more susceptible than Staphylococcus aureus.
