GREEN SYNTHESIS OF SILVER NANORODS USING AQUEOUS EXTRACT OF KALANCHOE PINNATA FRESH LEAVES AND ITS SYNERGISTIC EFFECT WITH CIPROFLOXACIN AND ANTIBIOFILM ACTIVITIES
Journal Title: International Journal of Pharmacy and Pharmaceutical Sciences - Year 2016, Vol 8, Issue 1
Abstract
Objective: The present study was aimed to investigate antibacterial and antibiofilm activities of AgNPs alone and its combination with ciprofloxacin against various human pathogenic bacteria strains.Methods: Reproducible, energy efficient, eco-friendly green synthesis of silver nanoparticles (AgNPs) using aqueous extract of Kalanchoe pinnata fresh leaves based on photoirradiation was carried out. These photosynthesized AgNPs were characterized by infrared spectroscopy, scanning electron microscopy with energy dispersive X-ray spectroscopy, transmission electron microscopy, zeta potential, differential scanning calorimetry, differential thermal analysis and particle size analysis.Results: From the results, AgNPs showed the desired physicochemical properties in terms of optical, structural, thermal and photocatalytic properties. Also, it is observed that Gram-negative bacteria strains are more vulnerable to both AgNPs as well as conjugating ciprofloxacin with AgNPs rather than Gram-positive bacteria strains.Conclusion: Enhanced antibacterial effect was observed in the conjugation of ciprofloxacin with AgNPs rather than antibiotic or AgNPs alone. AgNPs showed an excellent inhibitory effect in the formation of biofilm.Â
