Abstract :
Room temperature dielectric and antibacterial behavior of thiosemicarbazide capped low dimension Silver and Gold nanoparticles were studied. The effect of size on the properties, by capping silver (Ag) and gold (Au) nanoparticles by thiosemicarbazide (TSC) was investigated. The nanoparticles were synthesized by chemical reduction method. The structural formation, surface morphology, phase stability and crystalline nature were characterized by UV-Vis spectroscopy, Fourier transform Infra Red (FT-IR) spectroscopy, Differential Scanning Calorimeter (DSC), Scanning Electron Microscopy (SEM), Transmission Electron Microscopy (TEM) and Powder X-ray Diffraction (PXRD). Room temperature dielectric and Impedance spectroscopy were performed to understand the electrical transport behavior and the results indicated that TSC capped Ag nanoparticles have demonstrated better electrical properties. Also, antibacterial studies were performed on human pathogenic bacteria by agar well diffusion method which attested TSC capped Ag nanoparticles have better antibacterial properties.
