Antibacterial efficacy of silver nanoparticles synthesized employing Terminalia arjuna bark extract.
In the present investigation, we have explored simple, robust, inexpensive, and eco-friendly method for the synthesis of silver nanoparticles (AgNPs) using Terminalia arjuna bark extract (TA-AgNPs). Various parameters dictating the biosynthesis of TA-AgNPs such as time and temperature of reaction, concentration of AgNO3, and T. arjuna extract amount were investigated. Characterization of TA-AgNPs was done via UV-vis spectroscopy along with FT-IR, XRD, SEM and dynamic light scattering. The antimicrobial activity of TA-AgNPs was investigated against Escherichia coli. Comparable zone of inhibition was exhibited by TA-AgNPs. This study suggests that TA-AgNPs possesses significant antibacterial properties.
