Based on the results of the 2022 competition for grants from the Russian Science Foundation (RSF) in the priority area of the RSF activity “Conducting fundamental scientific research and exploratory scientific research by international research teams” (jointly with the National Natural Science Foundation of China (NSFC)) the project “«Ultra-bright and…
We have proposed, implemented and investigated a novel, efficient quantum emitter based on an atomic-sized Ag nanocluster in a plasmonic resonator. The quantum emitter enables the realization of: (1) ultra-bright fluorescence, (2) narrow-band emission down to 4 nm, (3) ultra-short fluorescence lifetime. The fluorescence cross-section of a quantum emitter is…
We report the design, fabrication, and experimental evaluation of a single-layer atom chip capable of continuous operation for laser cooling and trapping of neutral atoms. Traditional atom chips often use multilayer structures and operate in pulsed modes due to heat buildup from current-carrying wires. In this work, we optimized the…
We investigate how strong optical coupling between Cy7.5 dye molecules and gold (Au) nanorod plasmonic nanoparticles can influence the photobleaching (photodegradation) behavior of the dye. In typical conditions, dye molecules degrade when exposed to light due to transitions to reactive triplet states. However, when the dye molecules are strongly coupled…
We propose a new optical sensing method that enables real-time, ultra-fast, and extremely sensitive detection and imaging of single cardiac troponin-T (cTnT) molecules in complex biological samples like human blood serum. By combining an expanded laser excitation spot with fluorescent labeling strategies optimized for high photon collection, we overcome the…
