Sonochemical Coating - A Top Emerging Technology

The novel technology developed by BIU researchers, Prof. Aharon Gedanken and Dr. Ilana Perelshtein, is used in antibacterial masks, hospital bedding, air filters and more


Bar-Ilan University’s sonochemical coating technology has been named one of the Top 10 Emerging Technologies in Chemistry by the International Union of Pure and Applied Chemistry (IUPAC). The university congratulates Prof. (Emeritus) Aharon Gedanken and Dr. Ilana Perelshtein, of Bar-Ilan’s Institute of Nanotechnology & Advanced Materials (BINA), who are the pioneering developers of the technology, on this well-deserved recognition in the sonochemistry research field.

Sonochemistry applies (ultra)sonic waves to coat textiles with antibacterial nanoparticles to reduce the occurrence of bacterial infections. This technology stands out particularly for its enormous potential to manufacture innovative functional materials with value-added properties such as anti-bacterial /anti-viral masks produced by Sonovia, which have been in high demand during the COVID-19 pandemic.

Over the years, Prof. Gedanken’s research group has developed anti-bacterial coatings that are applied to textiles, such as hospital bedding and clothing. The coatings have proven to be very durable, thanks to the deep embedding of antibacterial nanoparticles in the fabric.  The sonochemical coating technology has also proven to be effective against viruses, such as influenza and COVID-19, as well as to protect users from various pollutants.
