New antibacterial nanotechnology based paint
10 September 2008A new paint containing nanoparticles of titanium dioxide is found to kill bacteria when it absorbs ultraviolet rays from the sun. Scientists have discovered that the new paint not only is antibacterial but it also helps in destroying dirt. These nanoparticles ultimately produces active molecules that help in cleaning the surfaces.
Scientists studied the behavior of different concentration of titanium dioxide in paint under different types of lights and intensities of lights. Researchers took common food poisoning bacteria E. Coli and found that paint containing stronger concentration of titanium dioxide nanoparticles is more successful in killing E. coli. Researchers were also able to conclude that the new paint formulation containing stronger concentration of titanium dioxide nanoparticle kills all bacteria under fluorescent light.
Researchers carried out similar experiments other paint formulations containing calcium carbonate, silica and talc and the antibacterial efficiency of the present formulations drops significantly.
The new paint formulation can have many advantages over the present commercial products. With the introduction of the new paint, the present healthcare system can be made more suitable for all types of patients as we can stop spreading of superbugs in hospitals. The new research can also be successfully utilized in food and pharmaceutical industries.
