The researchers from the Madrid Institute of Materials (ICMM) developed the technology, which contains the fine silver nanoparticles. The powder of this glass with silver nanoparticles is a powerful antibacterial and antifungal agent, inorganic, in the structure of nanoparticles which are included in the fiber sepiolita, clay with magnesium silicate.
The structure of glass allows silver nanoparticles to act very quickly, leaving a small amount of money provides a fast, safe and complete disinfection. Scientists explain this synergistic effect of the action of calcium ions that are leached from the glass.
The amount of silver leached from the glass powder during all types of bactericidal tests (with the gram-positive bacteria, gram-negative bacteria and yeast) was very low, about 28 parts per million, far below the acceptable level of toxicity. This formulation can be applied in many fields, including medicine, agriculture and food industry.
Currently scientists are working on understanding the processes of interaction resulting synergies and the development of possible combinations of types of glass-metal.
