Scale and generates uniform size, shape, and distribution. Top-down routes are usually not suitable for preparing uniform shapes and are hard to design and style nanoparticles with, using the most significant difficulty getting designing an imperfect surface structure. It has been reported that the grinding technique has been successfully utilized in the synthesis of magnetite nanoparticles by a topdown approach and that it considerably decreased the grinding time for you to 5 h in comparison with the previously reported research [73,97]. With all the assistance of top-down nanofabrication methods like lithography, monodispersed particles with controlled shapes and dimensions is often generated. The top-down strategy made use of to synthesize nanoparticles proves to be an alternative to overcome the disadvantages and obstacles on the bottom-up process [98,99]. The approaches described above have a number of benefits and disadvantages; having said that, comparing the two techniques has shown that the bottom-up process is cost-effective and facilitates the manufacturing of 2D and 3D supplies with several applications [78].
