Synthesis Of Nanomaterials: Top-Down And Bottom-Up

There are two main approaches to synthesize nanomaterial or nanoparticle. one is top-down approach and another is the bottom-up approach. let us discuss these approaches one by one: 1. top-down approach: as the name suggests, the top-down approach means from top (larger) to bottom (smaller). this approach is similar to making a statue made of .
