Abstract

Nanotechnology has now started leaving the confines of laboratories and conquering new applications to change our lives. Nanoparticles possess increased structural integrity as well as unique chemical, optical, mechanical, electronic and magnetic properties compared to large particles of bulk materials. These unique properties are derived due to variations in specific characteristics such as size, distribution and structure of particles. Metallic and non metallic nanoparticles of Pb, Au, Zn, Fe, and Ag have applications in various fields. Silver has been used since ancient times in medicine. Nanoparticles of silver were produced using different chemical, biological and physical methods. Nanoparticles thus produced showed good antibacterial and antifungal properties.The formation of silver nanoparticles is characterized using UV- visible absorption spectroscopy (surface Plasmon resonance at 418-420) and also by using Energy Dispersive Spectroscopy (EDX), Scanning electron microscopy (SEM), X-Ray diffraction (XRD) and FTIR (Fourier transform infrafed spectroscopy. The silver nanoparticles were used to prepare silver Nanoparticle embedded textile by different methods. Antibacterial and antifungal activity of this cloth was assessed. The results obtained were good showing great future for application of Nanoparticle embedded textiles in various fields. Keywords: Silver nanoparticles, UV-visible spectroscopy, Energy dispersive microscopy (EDX), scanning electron microscopy (SEM), X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), Nanoparticle embedded cloth, Percentage reduction assay.
