[@rhowanrivera]

What materials is examppe of top down approach?😃

[@qamarwali]

The top-down approach simply means to make a material by simply slicing a block into a small piece..... those pieces must be in the range of nano....
NPs by Mechanical Milling, ....... Nanosheet by etching ........
Nanosheet by sputtering....
2D graphene nanomaterials obtained from the 3D block

Is nano material or nano particles are same??

[@qamarwali]

*Nanomaterials* are general terms used, which include many such as nanoparticles, quantum dots, nanofibers, nanorods, carbon dots, CNTs,....etc.
Where as *nanoparticle* is one type of nanomaterials
