BGU-nanocoatingBGU researchers have developed novel surface coatings that will have a long-term effect and contain nanoparticles of safe metal ions and polymers with anti-viral and anti-microbial activity.

Preventing Surface-mediated Infection with SARS-Cov-2


The researchers assessed the effect of surfaces coated with nanoparticles of various metals on the infectivity of lentiviruses, which belong to the HIV family, in human cells. Findings show that surfaces coated with copper nanoparticles strongly block infection of the cells by the virus. These ongoing experiments show a huge potential for copper ions in preventing surface-mediated infection with SARS-CoV-2.

These anti-viral coatings can be painted or sprayed on surfaces. The coatings are based on polymers, which are the starting materials of plastics and paints, and contain nanoparticles of copper and other metals. The nanoparticles embedded in the polymer will enable controlled release of metal ions onto the coated surface.

Studies show that these ions have a strong anti-viral effect, which can eradicate virus particles that adhere to the surface. Because the release of ions is extremely slow, the coating can be effective for a long period of time – weeks and even months, and it will reduce the infectivity of the virus particles by more than 10-fold.

Coating Applicable for Places with Increased Risk of Contamination


The product will be efficient as a general anti-viral and anti-bacterial coating. It can be applicable for medical settings, as an anti-pathogenic substance in places with increased risk of contamination, such as hospitals, but also for home use, and in public spaces such as schools, airports, public transportation and cinemas.

This invention received the support of the Israel Innovation Authority, in response to a call for proposals for coping with the coronavirus. The project is one of 27 proposals submitted to the Israel Innovation Authority by BGN Technologies, the technology transfer company of BGU, based on innovative and diverse inventions of researchers at BGU and the National Institute for Biotechnology in the Negev (NIBN) for the prevention, diagnosis and treatment of COVID-19.
