Swedish researchers have discovered that a coating made of a cheap, electrically conductive plastic, which is widely present in smartphone smart screens, can influence Salmonella growth. Coating the medical device with this material makes the device more resistant to the intrusion of bacteria. It is a research and development idea for food machinery that easily contaminates food. Can also be used for wastewater treatment.
Researchers at the Nanomedicine Science Center at the Karolinska Institute in Sweden have recently discovered that a plastic in a smartphone screen can be used to stimulate the metabolism of germs. Researchers have induced the deception of bacteria to grow and die by adding or removing electrons to plastic surfaces. Once the technology matures, this method can be widely used in medical and wastewater management.
The researchers said that when bacteria attach to the surface of the object, they quickly grow a surface film called a "biofilm." Through the protection of this layer of biofilm, bacteria are present in our surroundings. However, if it is not in the hospital, some bacteria may cause infection and even life-threatening. Now researchers have discovered that the production of a coating of medical devices made of cheap conductive plastic called PEDOT can solve the problem of sterilization. The plastic is widely used in smart phone screens and it feeds back to the screen by touching the control voltage. When PEDOT is covered with electrons, it will affect the growth of Salmonella.
Lead researcher Agneta Richter-Dahlfors explained: “When bacteria land on electronically-charged PEDOT surfaces, they cannot replicate anymore. As the electrons continue to be released, the bacteria will continue to accumulate electrons to transform the bacteria into the energy they need to grow. Let the bacteria grow out of the biofilm and enhance the vitality of the bacteria, but if the electrons are absorbed, the bacterial biofilm will be destroyed, which can accelerate the death of the bacteria."
Professor Richter - Dahlfors said: "First of all, we can use this kind of material to coat medical devices and make them more resistant to bacterial invasion. In the waste water management industry, on the contrary, we need a lot of beneficial biofilm to create clean water, We can create a surface that promotes biofilm production."
The future development of the research team also hopes to integrate this technology into implanted medical devices so as to ensure the safety of implants during medical implants. This technology is published in the new issue of the journal biofilms and microbiomes.
