What are Synthesized Nanoparticles?
Synthesized nanoparticles are tiny particles that range from 1 to 100 nanometers in size. These particles are engineered at the molecular or atomic level to have specific properties and functionalities. The ability to manipulate matter at such a small scale has led to breakthroughs in various fields, including medicine, electronics, and environmental science.
Top-down methods involve breaking down larger materials into nanoparticles using techniques like milling, lithography, and etching.
Bottom-up methods build nanoparticles from atomic or molecular species through chemical reactions, self-assembly, or nucleation processes.
Common techniques include chemical vapor deposition, sol-gel processes, and hydrothermal synthesis.
