Abstract
- In recent era bacteria that were previously susceptible to different antibiotics are getting tolerant to these drugs. Novel nanoantibiotics can evade these emerging bacterial resistances. Thus, cefadroxil was conjugated to silver and gold nanoparticles (NPs) and resultant nanoconjugates (i.e., Cefd-AgNPs and Cefd-AuNPs) were examined against staphylococcus aureus ATCC 11632. Devised nanoconjugates were characterized by applying diverse range of characterization tools, including UV–visible, IR spectroscopy, scanning electron microscopy and atomic force microscopy (AFM). Moreover, bactericidal potential of Cefd-AgNPs and Cefd-AuNPs was compared with the efficacy of non-conjugated cefadroxil served as control. Experimentally obtained results show that conjugation of cefadroxil with gold and silver NPs enhanced the antibacterial potential of cefadroxil up to 3 and 2 times, respectively. Surface topography of the controlled and treated bacterial cells was also scanned by AFM. Moreover, AFM revealed that effective treatment time of cefadroxil (i.e., 8 h) also get reduced to one half upon conjugation of cefadroxil with both gold and silver (i.e., 4 h).
