dc.description.abstract | Background: At present, research on facile, green synthesis of nanoparticles has significantly increased because of its fast, one-step, cost-effective, time-efficient, and non-toxic nature. In this study, we have reported a single-step green synthesis of copper nanoparticles using cell wall polysaccharides of a hot spring origin, thermotolerant Bacillus species. Result: Copper nanoparticles were characterized using UV-visible spectrophotometry, fluorescence and Fourier transform infrared spectroscopy, scanning electron microscopy with energy dispersive spectroscopy, particle size, and zeta potential analyses. UV-visible spectra of synthesized copper nanoparticles exhibited a band cantered between 220–235 nm, characteristic spectra of copper oxide nanoparticles. Infrared spectra showed the band at 490-530 cm−1 corresponding to metal-oxygen or copper nanoparticle vibration, supporting the presence of copper oxide nanoparticles in the monoclinic phase. The energy dispersive spectra of copper nanoparticles exhibited a strong signal from elemental copper. The dynamic Light Scattering pattern confirmed the nanoparticle nature of the studied sample. These nanoparticles showed preferential activity against gram-negative pathogens, Salmonella typhi and Escherichia coli. The thermodynamic nature of the nanoparticles is also established for its antibacterial actions. Conclusions: The antibacterial action and its thermodynamics reinforce the possible use of copper nanoparticles as an alternative to commercially available antimicrobials. This study may open a new path for future studies to treat harmful microorganisms resistant to traditional antibiotics in a greener way. How to cite: Banerjee A, Roy RK, Sarkar S, et al.
