Non-Slippery Surface Technologies for Preventing the Growth of Biofilms

Majority of the infections that happen within the body of human beings are mainly because of bacteria build up. The infection being referred to, here is microbial in nature. The cells of bacteria form a strong base within the body via accumulation and they eventually become biofilms, which are adhesive like colonies. These colonies enable the bacteria to thrive and grow, but in the bargain cause different types of infections in the human body. 

Biofilms mostly end up growing on the surfaces of medical devices such as implants, heart valves, intravenous catheters, and urinary catheters. Scientists and researchers have come up with a certain surface technology that prevents the proliferation of biofilms. The creators of this technology call it “liquid-infused” polymers, which are basically surface coatings that are slippery in nature. This technology basically aims at strengthening the molecular set up of the polymers which as a result ensures the capacity to store huge amounts of lubricating liquids within the molecular framework. The characteristic features resemble those of a sponge. This ensures that are huge amount of lubricant can be stored which also has the capacity to move towards the surface and make it a slippery sort of a repellent. 

This system would thus, prevent bacteria from colonizing in that particular area. For the present research study, the scientists chose a silicone polymer (solid), the similar variant which is used in the present day’s medical tubing, saturated with silicone oil. Both these materials are non-toxic in nature and safe. In fact these materials are generally used in medical devices and extensively used products such as cosmetics.
