Antimicrobial resistance (AMR), which develops into superbugs, poses a significant challenge to global health leading to 4.95 million deaths in 2019, necessitating the exploration of alternative strategies. AMR is responsible for a significant economic cost estimated by the World Bank, where AMR could result in additional healthcare costs of US$ 1 trillion by 2050. Thus, overcoming these drawbacks is of great importance. Fortunately, the advent of 21st century nanotechnology provides an ample opportunity to develop diverse nanomaterials along with specific functionalization to treat bacteria, fungi, or viruses more effectively with the combination of innovative technologies. Among these, silver nanoparticles (AgNPs) are considered a great boon in the area of AMR, which has a long history of practice. However, in recent years, Ag‐based composites have been designed by scientists to enhance their antimicrobial effects at minimal concentrations, thereby depending on synergism. Thus, in this review, we provide an update on the recent advances in Ag‐based composites with metals, polymers, and carbon for various antimicrobial applications. In addition, we focused on the mechanisms that assist in tackling microbes and the toxicity of AgNPs. Thus, in this review, we highlight the synergistic effects of AgNP‐based composites in combating several microorganisms.

Glycine-modified chitosan anchored silver nanoparticles (SCG) were synthesized using a green method without a cross-linking agent. UV–Vis, FTIR, XRD, TEM and SEM techniques confirmed the formation of the SCG nanocomposite and silver nanoparticles. The SCG nanoparticles, estimated at 20 nm, are smaller than the chitosan stabilized Ag (SC) nanoparticles. The biological significance of the SCG nanoparticles was assessed through their anti-oxidant and antibacterial activities. SCG nanoparticles demonstrated significant anti-oxidant activity with an IC50 of 133 µg ml−1, surpassing that of SC nanoparticles. The ZoI of was found to be 30 mm for the S. aureus and E. coli bacterial strains indicating excellent antimicrobial activity. The efficiency of SCG nanoparticles in removing Pb2+ ions was tested using a batch adsorption process. A Central Composite Design (CCD) was employed to optimize the independent variables, and ANOVA results indicated the CCD model’s reliability and significance with a p-value < 0.0001. The SCG nanoparticles exhibited a high Pb2+ ion loading capacity of 270.2 mg g−1 from aqueous solution with a removal efficiency of 93%. Isotherm and kinetic investigations of the equilibrium data suggest the suitability of Langmuir and pseudo-second-order kinetic models. Thermodynamic studies revealed the process’s spontaneity and exothermic nature. The mechanism of adsorption was found to be ion exchange with a mean potential energy (Es) of 9.4 kJ/mol. These findings suggest that glycine-modified chitosan anchored silver nanoparticles have promising applications in biological and environmental domains.
