Superior Council for Scientific Research (CSIC) have developed a new family of biocides glasses that eliminate more than 99.9 percent of pathogens, a finding that could be very useful in the use of medical implants and for Water purification systems.
In addition, new glass finished with almost all pathogens without causing toxic effects to the environment microorganisms, explains the CSIC in a note.
The study is published in the journal PLoS One.
Zinc oxide (ZnO), one of the components used in these glasses, has high biocidal activity.
However, no experimental evidence of stable glasses contained zinc oxide above ten percent, at least until the multidisciplinary team of scientists study succeeded in obtaining glass containing zinc oxide up to 40 percent and he found that maintaining their properties.
In 2013 a patent application at the Spanish Patent and Trademark Office was deposited.
“The biocidal activity is effective against Gram bacteria (Escherichia coli), Gram positive (Staphylococcus aureus) and yeast (Candida krusei).
These products can act as dispensers of zinc ions in various media such as distilled water or without destilar- and can be produced by conventional manufacturing methods at low cost thereby responding to one of the current major challenges: biofouling caused diseases and stop by microorganisms, “said Jose Serafin Moya, a researcher at the Institute of Materials Science of Madrid.
Possible applications are the use in medical implants and surgical equipment but also in the manufacture of clothing to health centers, water purification systems, in food storage systems.
“It’s the first step to obtain new materials based biocides in these glasses, such as glassy nanofiber coatings for dental implants or surgical prosthesis,” says Moya.
