I am working with a company that wants to utilize the powers of silver through antimicrobials. The company is looking is to add these nanoparticles to their textile products in the dye bath. The company wants me to look at the most economic way of doing this whether investing in the equipment to manufacture or a supplier. Can someone point me in the right direction of the most efficient synthesis equipment to produce nanoparticles between 10 - 15 nm. What type of equipment is needed to produce on a mass scale. Please help me? What other info is needed to spec out equipment?
