Surfactants are often used to improve the dispersion of nanoparticles in a solution. These molecules have both hydrophilic and hydrophobic ends, allowing them to interact with both the solvent and the nanoparticles. This interaction helps to prevent agglomeration and stabilize the dispersion. Common surfactants include Sodium Dodecyl Sulfate (SDS) and Polyvinylpyrrolidone (PVP).
