Several types of solvents are used in nanotechnology, each with its own set of properties suitable for different applications:
1. Polar Solvents: These include water, ethanol, and methanol. They are often used for synthesizing hydrophilic nanoparticles. 2. Non-Polar Solvents: Examples are hexane and toluene, used for hydrophobic nanoparticles. 3. Ionic Liquids: These are salts in the liquid state and are used for their unique properties like low volatility and high thermal stability. 4. Supercritical Fluids: CO2 in its supercritical state is used for its unique solvating properties and environmentally friendly nature.
