Publication number: 20220229057Abstract: A method of detecting a presence, amount and/or type of a pathogenic organism in a substrate is provided. The method is effected by contacting a sample suspected as containing the pathogenic organism or a portion thereof with an electrode, thereafter contacting the electrode with an aptamer that selectively binds to said pathogenic organism; thereafter contacting the electrode with an agent that participates in an electrochemically detectable reaction and thereafter perform the electrochemical reaction while using the electrode. The electric signal produced by the reaction is indicative of a presence and/or amount of the pathogenic organism. Also provided are a sensing system and kits usable for practicing the method, and use of the method for determining a suitable agent for reducing a load of a pathogenic organism in a substrate.Type: ApplicationFiled: May 28, 2020Publication date: July 21, 2022Applicants: Ramot at Tel-Aviv University Ltd., Adama Makhteshim Ltd.Inventors: Fernando PATOLSKY, Boris FILANOVSKY, Vadim KRIVITSKY, Yoav AVIDOR

Patent number: 11193888Abstract: A system featuring a substrate and a multiplicity of nanostructures arranged on the substrate is provided. At least one portion of the nanostructures feature a capturing moiety covalently attached to a surface thereof and at least another portion of the nanostructures, which can be the same or different from the first portion, feature a light-activatable moiety covalently attached to a surface thereof. The capturing moiety is such that selectively interacts with an analyte, and the light-activatable moiety generates, upon exposure to light, a reactive moiety that interferes with an interaction of the capturing moiety and the analyte. Further provided are systems featuring a substrate and a multiplicity of nanostructures aligned generally vertically to the substrate, at least a portion of these nanostructures being branched nanostructures. Uses of the systems in extracting, and optionally identifying, the analyte from a sample are also provided.Type: GrantFiled: March 29, 2018Date of Patent: December 7, 2021Assignee: Ramot at Tel-Aviv University Ltd.Inventors: Fernando Patolsky, Vadim Krivitsky
