  • Antibacterial activity of silver-graphene quantum dots nanocomposites against gram-positive and gram-negative bacteria
    Patent number: 9931609
    Abstract: 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 ?g/mL of Ag-GQDs, a non-toxic level for human cells, exhibits strong antibacterial activity against both Gram-Positive and Gram-Negative Bacteria.
