AB  - A novel and effective antibacterial agent based on a combination of copper nanoparticles (CuNPs) and polypyrrole (PPy) is presented. By using a straightforward in situ polymerization method in water, a copper/polypyrrole (Cu/PPy) nanocomposite with spherical CuNPs, around 25 nm in diameter, uniformly dispersed throughout a granular PPy matrix, was characterized and subjected to determination of antibacterial activity toward E. coli, and S. aureus. In this survey, the synergistic engagement of various features of CuNPs and PPy against bacteria was somewhat expected. After a 24 h interaction with S. aureus, already 2 ppm of Cu/PPy with only 9.45 wt% content of Cu is acting almost completely cidal, with 99.17 % bacterial growth inhibition, while 10 ppm has a cidal value of 99.99 % at the same time. Safe and environmentally acceptable concentrations of Cu/PPy indicate that it is convenient as an antibacterial agent for wider use.

AB  - A novel and favorable antibacterial agent as a combination of copper nanoparticles (CuNPs) and polypyrrole (PPy) is presented. By simple in situ polymerization method, copper/polypyrrole (Cu/PPy) nanocomposite with spherical CuNPs, around 25 nm in diameter, uniformly dispersed throughout PPy matrix with granular morphology, was characterized and subjected to determination of antibacterial activity toward bacteria Escherichia coli and Staphylococcus aureus. Knowing that when acting alone, CuNPs and PPy have already shown antimicrobial responce, their mutual and synergetic engagement against bacteria in this survey is somewhat expected. After a twenty-four-hour interaction with S. aureus, already 2 ppm of Cu/PPy with only 9.45 wt% content of Cu is acting almost completely cidal, with 99.17% of bacterial growth inhibition. Such nanocomposite could easily find application in water disinfection, soil sterilization and food preservation.
