biosensors Ester H. Segal (Hebrew: אסתר סגל) is an Israeli nanotechnology researcher and professor in the Department of Biotechnology and Food Engineering at the Technion - Israel Institute of Technology, where she heads the Laboratory for Multifunctional Nanomaterials.
[2] Segal competed her graduate research with Moshe Narkis at the Technion - Israel Institute of Technology, where she developed electrically conductive polymer systems and their application as sensors for volatile organic compounds.
These sensors, containing pores between 10 and 100 nm detect analytes such as proteins,[6][7] DNA,[8] whole bacteria cells,[9][10][11] amphipathic molecules on lipid bilayers,[12] organophosphorus compounds,[13] heavy metal ions,[14] and proteolytic products from enzymatic activity.
[19] Diffraction gratings Segal's research group engineered microstructured silicon optical sensors for the detection of microorganisms, including bacteria and fungi, in clinical samples and food.
[21][22] Her group (in collaboration with the Department of Urology at the Bnai Zion hospital and Ha'Emek Medical Center) developed a means of rapid antimicrobial susceptibility testing for clinical samples.
