Created Smart Coating with Selective Absorption Function


Scientists from Canada’s McMaster University have created a surface coating that is capable of absorbing only one «target» substance, and all others repel.

Created Smart Coating with Selective Absorption Function

We all know about special coatings that resist almost all substances that fall on them. They can be used to protect appliances from destruction or prevent bacteria from accumulating in the kitchen. However, in some situations it is required to be absorbed any one specific component. Canadian scientists have found a solution to this problem.

A team from McMaster University introduced a surface coating that absorbs one «target» substance, while ignoring all others. The composition of the invention includes a safe lubricant and specific biomolecules that are able to bind to the necessary component of the environment, allowing them to pass through. This combination provides a selective effect and allows you to choose which substance you want to react with..

The inventors say their smart coating will find use in medical implants, among other things. It will be able to repel blood and infections,  reducing the risk of blood clots and infection, while interacting with muscles, organs, or bone to better anchor and reduce the likelihood of rejection. The technology will also make it easier to examine organic fluids such as blood or urine by absorbing only certain viruses, bacteria or cells..

We also wrote earlier that Chinese scientists, inspired by the evil T-1000 from «Terminator», began to work on the creation of a flexible robot with liquid metal that can independently change shape under the influence of stress.
