2024 ANNUAL REPORT

| 51 | Measurements to Improve the Sensitivity of Fluorescence-Based Immunoassays." Biosensors, 2024. Dr. Desiatov Boris Faculty of Engineering Quantum Electro-Optic Devices Research Areas • Optoelectronic device • Quantum optics • Quantum information science • Meta-materials • Nano-photonics • Nanofabrication • Non-linear optics Abstract The world of quantum optics holds enormous potential to address a large variety of unsolved problems in sensing, information processing, computation, and precise measurements. Taking the advantage of well-developed nanofabrication processes, on-chip integrated quantum photonics is a promising platform for the realization of quantum optics technology. Artistic illustration of the optoelectronic on-chip quantum circuit.

Prof. Deutsch Moshe Department of Physics Soft Matter Interfaces Research Areas • Experimental X-ray studies of surface properties of liquid metals • Simple liquids and liquid crystals • Structure of mono-molecular Langmuir films • Dynamical X-ray diffraction phenomena in perfect crystals • High-precision crystal binding studies • X-ray emission and absorption spectroscopy • Synchrotron radiation and its applications Abstract Liquid surfaces and interfaces abound in living matter, industrial processes, and everyday life and activities. Elucidating their structure is a prerequisite to understanding the functionalities involved and, thus, is highly important. We employ synchrotron and lab-source X-ray methods to experimentally study the structure of such interfaces with sub-molecular resolution under a broad range of conditions. We study interfaces of simple liquids, selected oil/water interfaces, liquid metals and alloys, deep eutectics, room-temperature ionic liquids, and more.
