Characterization methods
Nanomaterials are made in a variety of ways, which are divided into two general categories: top-down and bottom-up. In video tutorial number 7, top-down methods for making nanomaterials were introduced. In the rest of that video, in this section, you will learn about the second category of these methods, bottom-up methods.
One of the interesting phenomena in nature is the existence of nanomaterials and nanostructures in living organisms, plants, and animals, and scientists are inspired by these nanoscale phenomena to create products based on nanotechnology. This educational video discusses some examples of these cases.
