The process of coating materials by immersing layer by layer with antibacterial chemicals

            Dip coating is a technique that allows chemical substances to penetrate the surface of various materials, such as both internal and external medical devices. It can also coat surfaces with nanoscale thickness by controlling the number of coating cycles. Generally, it is commonly used for small-sized medical equipment only. Researchers have thus developed a method of coating materials by immersing them layer by layer with chemical substances possessing antibacterial properties, which can be applied to larger equipment.
