Abstract

Introduction: In recent years, green synthesis of silver nanoparticles (AgNPs) has gained much interest from chemists and researchers and also
increasing commercial demand for nanoparticles due to their wide applicability in various areas such as electronics, catalysis, chemistry, energy, and
medicine.
Objective: In the present study, AgNPs were synthesized from 1 mM AgNO
solution through the extract of Avicennia alba leaves. It is a cost-effective
and eco-friendly technique. The nature of AgNPs synthesized was analyzed by UV-visible spectroscopy, Fourier transform infrared spectroscopy, and
scanning electron microscopy. The antibacterial potential of synthesized AgNPs was compared with that of standard antibiotic by agar well diffusion
method.

Results: The antibacterial activity results revealed that A. alba leaf AgNPs showed a significant zone of inhibition against the majority of tested
bacteria than the streptomycin. Arthrobacter protophormiae and Proteus mirabilis were found to be two-fold sensitive to AgNPs of A. alba leaf than
to positive control, streptomycin. Rhodococcus rhodochrous was found sensitive only to AgNPs but not to streptomycin. Other remaining sensitive
bacteria exhibited more or less same susceptibility to AgNPs and streptomycin.
Conclusion: AgNPs of A. alba leaf showed broad spectrum antibacterial activity and may be a good alternative therapeutic approach in future.
Keywords: Green synthesis, Silver nanoparticles, Avicennia alba leaves, Fourier transform infrared spectroscopy, Scanning electron microscopy,
Antibacterial activity.
