Antibacterial activity of silver-graphene quantum dots nanocomposites against gram-positive and gram-negative bacteria

<p id=”p-0001″ num=”0000″>The invention provides a composite of silver nanoparticles decorated with graphene quantum dots (Ag-GQDs) using pulsed laser synthesis. The nanocomposites were functionalized with polyethylene glycol (PEG). A concentration of 150 μg/mL of Ag-GQDs, a non-toxic level for human cells, exhibits strong antibacterial activity against both Gram-Positive and Gram-Negative Bacteria.</p>
