- Sol-Gel Process: This method involves the transition of a solution into a solid gel phase. It is widely used for creating nanoparticles and thin films. - Chemical Vapor Deposition (CVD): This technique is used to produce high-purity, high-performance solid materials. It is commonly used in the semiconductor industry to create thin films. - Hydrothermal Synthesis: This method involves the use of aqueous solutions at high temperatures and pressures to grow nanostructures. - Electrochemical Deposition: This technique uses an electrical current to reduce metal ions in a solution, depositing them onto a substrate to form nanocoatings. - Co-precipitation: In this method, multiple reactants are precipitated simultaneously to form nanoparticles. It is often used for the production of magnetic nanoparticles.
