Publication: Optical methods for detection of single biomolecules

We discuss advanced optical and nanophotonic techniques for detecting single biomolecules with extremely high sensitivity, down to single-molecule levels. We describe and show how modern optical methods — including fluorescence imaging, plasmonics, and nanostructure-enhanced sensing — can be used to visualize single molecules, detect ultra-low analyte concentrations directly in complex…

Publication: Quantum engineering of the radiative properties

We investigate how strong light–matter interactions can be used to engineer the radiative (light emission) properties of complex nanoscale systems composed of fluorescent dye molecules embedded in a polydopamine matrix and coupled to metallic nanoparticles. Polydopamine is a common biocompatible adhesive material, but it typically quenches fluorescence of embedded dyes…

Publication: Optical detection of infectious SARS-CoV-2 virions

The paper presents a novel optical microscopy method for directly detecting infectious SARS-CoV-2 viral particles in clinical samples by counting spike proteins on individual virions. Traditional virus detection techniques often measure viral genomes or specific proteins but cannot differentiate between infectious particles and non-infectious debris. We address this limitation by…

Publication: Silver cluster fluorescence in a plasmonic cavity

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…

Publication: Efficient Loading of an Atom Chip

We study a method to improve the loading efficiency of atoms into a magneto-optical trap located near an atom chip. We propose focusing a slow atomic beam using a two-dimensional magneto-optical trap (2D MOT) placed between a low-velocity intense source and the chip. This focusing compresses the atomic beam into…

Publication: Single-layer atom chip for continuous operation

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…

Publication: Atom femtosecond optical trap

We report the development and experimental demonstration of a femtosecond pulsed optical dipole trap for neutral atoms (rubidium) in which spectral filtering of the broadband laser light is used to significantly increase atom trapping lifetime. This spectral filtering removes near-resonant frequency components, reducing atom heating and allowing atoms to remain…
