SUSTAINABLE colloidal systems based on silver and colloidal systems based on silver-coated silicon dioxide and methods for producing stable colloidal systems based on silver and colloidal systems based on silver-coated silicon dioxide
Methods for preparing silver colloids and silica-coated silver colloids are disclosed. The silver colloids may be prepared by heating a silver-containing solution, combining the heated silver-containing solution with an acid solution, and cooling the combined solutions to form a silver colloid containing silver particles. The silver particles in the silver colloid can further be coated with silica. A method for preparing antimicrobial coatings is also disclosed.
