WebThe synthesis of green nanoparticles is categorized into two classes, namely “top-down” and “bottom-up” based on the way of nanoparticle formation (Fig. 1 ). In the “top-down” approach, the dimension of nanoparticles was larger and hence a mechanical method or the additions of acids are necessary to decrease the particle size of the nanoparticles. WebBottom-up synthesis methods are often termed “wet” methods since they involve batches of solvents and other chemicals. Additionally, the particles often must be stabilized or capped in solution to ensure that they do not …
