Nanomaterial Synthesis Methods: Pros, Cons and Economics ...

2021-07-16  For nanomaterials, there are two main classes of synthesis methods, called ‘top-down’ and ‘bottom-up.’ Top-down methods, such as milling, take bulk materials and break them down in size. The alternative, bottom-up methods use chemical processes to build nanomaterials from scratch. Many synthesis methods fall into the bottom-up category and involve the nucleation of seed particles from ...
