Chapter 4: Synthesis of Nanomaterials

Nanomaterials can be synthesized using top-down and bottom-up approaches, each with its own advantages and limitations. Common synthesis techniques include ball milling, lithography, sol-gel methods, and chemical vapor deposition, alongside biological and green synthesis methods. The choice of synthesis method is influenced by material type, desired properties, scalability, cost, and environmental considerations.
