Patch nanoparticles can suck bacteria from wounds

Scientists are developing a grid of nano wires capable of pulling germs from the wound, thus speeding up the healing process. Novelty was devoted to the report presented at the 61st Congress of the American Vacuum Society, and briefly about her reports Science News.


Nanofibers have long been used as a substrate (frame) for the cultivation of biological tissues. Taking this principle is adopted, scientists have begun to develop nanoset able to catch bacteria from open wounds. Having experienced the fibers of different sizes, the researchers concluded that the microbes easier to move to a structure comparable to their diameter.

When immersed in a Petri dish with Staphylococcus aureus (this bacterium causes many diseases) microbes quickly filled the fiber surface width of 500 nanometers and ignored more volume elements. The scientists also experimented with different coatings. Coliform bacteria (they are also responsible for non-healing wounds) readily docked with the fibers coated with allylamine (colorless organic compound), but stayed away from the fibers in acrylic acid.

Now researchers are going to test nanoset on composite materials, similar in structure to human skin. The aim of scientists - to create a "smart" adhesive that will not allow infections to develop. To save the patient from infection, the doctor will be enough to stick nanoplastyr the damaged area and a few minutes to unstick it.
