Synthesis, optimization and characterization of silver nanoparticles using the catkin extract of Piper longum for bactericidal effect against food-borne pathogens via conventional and mathematical approaches.

ABSTRACT: Inspired with an increasing environmental awareness, we performed an eco-friendly amenable process for the synthesis of silver nanoparticles (AgNPs) using the catkins of Piper longum as an alternative approach with the existing methods of using plant extracts. The fabrication of nanoparticles occurred within 10 min. This was initially observed by colour change of the solution. UV-visible spectroscopic studies (UV-Vis) were performed for further confirmation. The analysis elucidated that the surface plasmon resonance (SPR) was specifically corresponding to AgNPs. Fourier transform infrared spectrophotometry (FTIR) studies indicated that polyphenols could possibly be the encapsulating agents. The size and shape of the nanoparticles was analysed using Transmission electron microscopy (TEM). T
