May 18, 2021 The team, led by BGU’s Department of Chemistry Prof. Raz Jelinek, and postdoc in his lab Dr. RavitMalishev , tested their molecular tweezers on the Staphylococcus aureus (Staph) bacteria. Staph infections have an estimated mortality rate in the US of over 25%, and as much as 40% for drug-resistant strains. The researchers developed two specific tweezers that bind and either disrupt biofilm formation or break existing biofilms. “Our discovery prevents infection without building up antibiotic resistance. As such, it might even be preferable to construct treatments based on molecular tweezers rather than antibiotics,” says Prof. Jelinek, who is also Ben-Gurion University’s Vice President of Research & Development and a member of the Ilse Katz Institute for Nanoscale Science and Technology. “Importantly, binding the tweezers to the biofilm disrupts its protective capabilities. In consequence, the bacterial pathogens become, on the one hand, much less virulent to
