Abstract: The nanopartical offer several advantages over other conventional drug delivery systems. Nanoparticles have gained importance in technological advancements due to their modifiable physical, chemical and biological properties with improved performance over their bulk foils. Nanoparticles can simply move in the body due to their small size and reach very complex organs through divers routes. The high stability, controlled drug release makes nanoparticles the most suitable drug delivery system. The study of different methods of synthesis of nanoparticles is essential to obtain desired nanoparticle with specific sizes and shapes. They are suitable candidates for various marketable and local application, which include imaging, catalysis medical application and environmental application. Keywords: Nanopartical, bulk foil, divers routes.
1. INTRODUCTION It may appear that Nanotechnology is of recent origin. Actually, it dates back several thousands of years like use of gold nanoparticles in tinting of glass used to make goblets and also to cure certain diseases. This is because nanopartical have altered properties than their base metallic elements.(15) In 1875 Faraday was the first person to recognize metallic nanoparticles as unique nanostructures with distinctive properties. Various synthesis methods are adopted to for the preparation of metallic distinctive properties. Various synthesis methods are adopted to for the preparation of metallic nanoparticles. These are either top down or bottom up approach. However, each of these approaches has certain advantages and limitations. Both these methods are physic- chemical in nature.(2) Synthesis approaches: 1. Top-down approach The top-down approach uses initial macroscopic structures. The methods begin with larger particles which are reduced to nanoparticles after a sequence of operations performed over them. Main shortcomingof these methods are that they involve large installation and hug capital is required for set up. The methods are quite expensive and hot suitable for large-scale production. The method is suitable for laboratory experimentation. The approach is based upon the grinding of materials. These methods are not suitable for soft sample.(16,10) Methods in Top-down approach: 1. Physical vapour deposition. 2. Chemical vapour deposition. 3. Ion implantation.
