Interference-free superposition of nonzero order light modes: Functionalized optical landscapes
In this paper, we utilize the incoherent superposition of nonzero order light modes. We show that this approach brings an additional degree of freedom to the generation of optical fields and notably the...
PublicationsSpatially optimized gene transfection by laser-induced breakdown of optically trapped nanoparticles
We demonstrate laser-induced breakdown of an optically trapped nanoparticle with a nanosecond laser pulse. Controllable cavitation within a microscope sample was achieved, generating shear stress to monolayers...
PublicationsDynamic size tuning of multidimensional optically bound matter
We generate and dynamically control one-, two- and three-dimensional optically bound structures of soft matter in the geometry of counter-propagating incoherent laser beams. We report results for the Bessel,...
PublicationsSpeed enhancement of multi-particle chain in a traveling standing wave
A moving array of optical traps created by interference of two counter-propagating evanescent waves has been used for delivery of particle chains up to 18 micro-particles long immersed in water. The particles...
PublicationsWavefront corrected light sheet microscopy in turbid media
Light sheet microscopy is a powerful method for three-dimensional imaging of large biological specimens. However, its imaging ability is greatly diminished by sample scattering and aberrations. Optical...
PublicationsCorrelations between photocatalytic activity and chemical structure of Cu-modified TiO2-SiO2 nanoparticle composites
Copper-modified TiO2-SiO2 photocatalysts were prepared by sol-gel method based on organic copper, silicon and titanium precursors. Copper concentration varied from 0.1 to 3.0 mol%. A widely applied model...
PublicationsUnderwater pulse electrical diaphragm discharges for surface treatment of fibrous polymeric materials
Preliminary results on physical characteristics of pulsed underwater diaphragm electrical discharges are presented. The discharges burning in tap water, water-chelaton solutions, and some other water-based...
PublicationsHF plasma pencil and DC diaphragm discharge in liquids – diagnostics and applications
The plasma device for fine hand manipulation called "plasma pencil" and diaphragm discharges is a special type of plasma nozzle generating high pressure non-isothermal plasma for different possible applications...
PublicationsAutomated laser guidance of neuronal growth cones using a spatial light modulator
The growth cone of a developing neuron can be guided using a focused infra-red (IR) laser beam [1]. In previous setups this process has required a significant amount of user intervention to adjust continuously...
PublicationsHolographic display system for restoration of sight to the blind
Objective. We present a holographic near-the-eye display system enabling optical approaches for sight restoration to the blind, such as photovoltaic retinal prosthesis, optogenetic and other photoactivation...
