Abstract
In the present study, we have reported the green synthesis of gold nanoparticles (GNPs), using potato starch as reducing as well as stabilizing agent in buffer solution. The resulting GNPs were near spherical in shape with average diameter of 15 ± 5 nm. The synthesized nanoparticles were characterized and investigated for their antibacterial properties against both gram negative (Escherichia coli) and gram positive bacteria (Staphylococcus epidermidis). These GNPs were found to possess significant dose dependent antibacterial activity against both strains. GNPs showed a significant catalytic activity and can easily be functionalized using a simple, greener method for various applications in non-polar chemistry. The overall results suggested the formed multifunctional starch encapsulated GNPs (St-GNPs) can be useful as antibacterial agent, catalyst and for wide variety of environmental, biomedical, and industrial chemical application.
