While manufacturing silver nanoparticles (Ag-NPs) by green chemical rout, here we presented a naive, bottom-up and green rout for the production of Ag-NPs by successfully employed for catalytic degradation of ibuprofen drug. The Cefditoren derived silver nanoparticles were optimized by Ultra Violet–Visible spectroscopy, X-ray diffraction, Fourier transform infrared spectroscopy and high-resolution transmission electron microscope analysis. This work has shown that a comprehensive degradation of ibuprofen of about ~ 99.9% was attained in little reaction time (60 s) by nimble Cef-Ag-NPs. The precision was achieved in percent degradation of ibuprofen by altering and adjusting the reaction period, quantity, and concentration of catalyst. The calculated rate constant (K) value for ibuprofen catalytic degradation was attained in 8 × 10−2 S−1 by plotting in concentration (C) versus time (s). The bactericidal potency of fabricated Cef-Ag-NPs was also assessed for the preferred Gram-positive Staphylococcus aureus (S. aureus) and Streptococcus pyogenes (S. pyogens) and Gram-negative Escherichia coli (E. coli) and Salmonella typhimurium (S. typhimurium) bacterial species. The outcomes were inveterate that common antibiotic in amalgamation with silver nanoparticles had strong and drastic antibacterial effects as compared to individually treated antibiotic and silver ions. On behalf of these consequences, it was realized that concerning Cef-Ag-NPs would serve as fast, economic, and less conventional candidates for other harmful and antibiotic-resistant pathogens.
