Gram-positive and gram-negative bacteria are combated using Dpep-silver nanoclusters (AgNCs) in the antibacterial assay. The Ag + ions that are internalized in both types of bacteria can induce reactive oxygen species (ROS) inside bacterial cells. Dpep-AgNCs internalize into gram-negative bacteria through interactions with lipopolysaccharides (LPS) and porins, while they enter gram-positive bacteria through interactions with peptidoglycan
