Abstract

To evaluate the photocatalytic and antibacterial activity of a biologically synthesized AgNPs mediated by palm (Borassus flabellifer) water against human pathogens. It is a potential candidate for preparing nanomedicine for constipation. 1mM of AgNO3 is prepared and mixed with an appropriate volume of Pathaneer and the reaction was made up to 100ml. The AgNPs were characterized by X-ray diffraction, FT-IR, UV-Vis analysis and HRTEM. The photocatalytic property and the antibacterial activity were carried out for the prepared AgNPs. The powder X-ray diffraction investigation reveals the FCC structure of AgNPs with a crystalline size of 27nm and a lattice strain of 0.4283. FT-IR confirms the presence of Ag+ from UV-Vis, the energy band gap was found to be 2.92 eV. HRTEM was used to calculate the diameter of AgNPs as 5-10nm. In Borassus flabellifer, the percentage degradation state of AgNPs was estimated as 87% at 180 minutes. AgNPs derived from Pathaneer have a large impact as antibacterial in the biomedical field. Since the aggressive chemicals are not involved in the preparation of AgNPs, it is used as an alternated biomedicine to reduce the toxicity of AgNPs and the photo degradation efficiency is high hence suitable for solar cells as well. Keywords: AgNPs; HRTEM; photocatalytic; antibacterial activity

Highlights

Silver-based nano compounds are used in chemical [1,2], physical [3,4] and biological process [5,6]
The results indicated that the AgNPs synthesized from Pathaneer have stronger antibacterial activity than AgNo3 and the standard antibiotic (Lysol)
The synthesis of silver nanoparticles using Pathaneer was reported for the first time

Summary

Introduction

Silver-based nano compounds are used in chemical [1,2], physical [3,4] and biological process [5,6]. Green biosynthesis of AgNPs is applied as an antibacterial agent and a catalyst [8]. Several parts of the plant are used as a reducing agent to attain silver nanoparticles [9,10,11,12,13]. Silver has attracted more attention because of their antibacterial activity. Pathaneer obtained from the Palmyra sap usually involves tapping the top shoots and collecting the saturated juice in hanging clay pots overnight from palm trees. These clay pots are coated with calcium carbonate to reduce fermentation
