techniques including both Top-down and Bottom-up approaches have been developed and applied for the synthesis of the nanoparticles. In the Top-down approach a block of a bulk material is whittled or sculptured to get the nanosized particle. The Top-down approaches include milling or attrition, lithography etc. The main disadvantage of the Top-down approach is the imperfection of the surface ...
