Any bacteria in contact with microscopic particles will die in a matter of seconds, talk to experts. About the work and trials of a new antibacterial agent tells the publication of Optical Materials Express.
Scientists used the phenomenon of plasma resonance. Each piece of gold under certain conditions, creates electromagnetic waves, enough to send the light to the desired angle. As a result, the nanoparticles become the function of the antibiotic starting to produce energy. In the experiment, scientists were able to heat the particles to 200 degrees. The introduction of even a small number of material into a bacterial cell kills her in a moment.
Each nanoparticle is a gold disk with a diameter of 400 nanometers. Irradiated particles, the experiment proved that quickly kill the bacteria Escherichia coli, Bacillus subtilis, Exiguobacterium. The destruction occurs in a matter of seconds.
