Abstract

Nickel and Copper nanoparticles were synthesized by simple chemical method and studied for antimicrobial activities. The size of synthesized Nickel and Copper nanoparticles was found to be 24.00 nm and 13.13 nm respectively. The XRD analysis reveals the crystal system of Nickel and Copper nanoparticles. Copper nanoparticles were found orthorhombic whereas the nickel nanoparticles were monoclinic. The antimicrobial activities of Nickel and Copper nanoparticles dispersed in DMSO was investigated. Comparative sensitivity test of these synthesized nanoparticles was carried out against three pathogenic micro-organisms (Gram negative bacteria), viz. Escherichia coli, Klebsiella pneumoniae and Pneumonia Typhus, using agar diffusion cup plate method. Copper and Nickel nanoparticles have shown appreciable sensitivity at 100 μg/ml against all test micro-organisms. Comparatively, Copper nanoparticles were found to exhibit higher zone of inhibition (ZOI) than Nickel nanoparticles.

Highlights

Metallic nanoparticles (NPs) are known for potential application in catalysis, electronics, optoelectronics, information stock, biosensors, and surface enhanced Raman spectroscopy (SERS), their synthesis and properties have been studied in depth by several workers [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]
Applying Debye – Scherrer equation to the XRD pattern of the copper nanoparticles, it has been found that the average size of nanoparticles is 13.13 nm, bravais lattice is primitive, space group is pccn (56) and 2Θ 1⁄4 42.045 [22]
XRD pattern showed that the size of nickel nanoparticles was 24.0 nm and has maximum intensity diffraction peak at 2Θ 1⁄4 12.50290 which indicate the presence of crystalline structure and the crystal system is monoclinic [23]

Summary

Introduction

Metallic nanoparticles (NPs) are known for potential application in catalysis, electronics, optoelectronics, information stock, biosensors, and surface enhanced Raman spectroscopy (SERS), their synthesis and properties have been studied in depth by several workers [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]. These particles have a wide functional diversity and can exist as common structural elements or composites compared to bulk materials.
