Green Synthesis and Characterization of Silver Nanoparticle (AgNPs) using Pandanus Atrocarpus Extract

Abstract

Nanotechnology is among most revolutionized fields in upcoming and advanced technologies. Silver nanoparticles were synthesized through Green route which is considered as eco-friendly, cheap and nontoxic method. Pandanus atrocarpus extract (PAE) was used as a source of reducing agents because of the presence of phytocompounds. Metal salts were allowed to react with extract and reduced to metal nanoparticles. Formation of nanoparticles, their size and morphology was confirmed by characterization techniques such as UV-Vis, FTIR, SEM, and XRD. The UV–Vis spectrum of silver nanoparticles revealed a characteristic surface plasmon resonance (SPR) peak at 432nm to 440nm. . In all of the AgNP samples, the two peak shifts after AgNP synthesis were observed as: 3338 to 3325/3326 cm^-1 and 1638 to 1634/1635 cm^-1, as recorded for AgNP samples 1 to 5. The peak at 3338 belongs to the –OH group. Second important stretching vibration is recorded from 1638 to 1634/1635 cm^-1 which, although may be considered as amide group of proteins as well as benzene ring containing aromatic compounds. The XRD peaks that indicate the structure face centred cubic of metallic AgNPs. FESEM analysis indicates spherical shape of the nanoparticles with the smallest diameter of 14 nm. AgNPs play an important role in nanoscience and nanotechnology, particularly in nanomedicine. Therefore, the present work has been undertaken to synthesize the AgNPs using extract of medicinal plant, Pandanus atrocarpus, to characterize using advanced techniques.
