Entanglement of two individual atoms using the Rydberg blockade

, 2008
We report on our recent progress on the manipulation of single rubidium atoms trapped in optical tweezers and the generation of entanglement between two atoms, each individually trapped in neighboring tweezers.

Microscopic Control and Detection of Ultracold Strontium in Optical-Tweezer Arrays

Physical Review X, 2018
Optical tweezers provide a versatile platform for the manipulation and detection of single atoms. Here, we use optical tweezers to demonstrate a set of tools for the microscopic control of atomic strontium, which has two valence electrons.

Influence of Laser Intensity Fluctuation on Single-Cesium Atom Trapping Lifetime in a 1064-nm Microscopic Optical Tweezer

Applied Sciences, 2020
An optical tweezer composed of a strongly focused single-spatial-mode Gaussian beam of a red-detuned 1064-nm laser can confine a single-cesium (Cs) atom at the strongest point of the light intensity.

Optical shield: measuring viscosity of turbid fluids using optical tweezers [PDF]

, 2012
The viscosity of a fluid can be measured by tracking the motion of a suspended micron-sized particle trapped by optical tweezers. However, when the particle density is high, additional particles entering the trap compromise the tracking procedure and ...

DNA Barcoding‐Enabled Tracking of Lipid Nanoparticles: Drug‐Loading‐Dependent Biodistribution and Tumor Microenvironment Targeting

Advanced Healthcare Materials, EarlyView.
In this study, lipid nanoparticles are tracked in vivo using DNA barcodes to determine how varying drug loadings affect their delivery behaviors in mice. A cost‐effective strategy is developed for simultaneously monitoring the biodistribution of a library of lipid nanoparticles (LNPs).

Fundamental constraints on particle tracking with optical tweezers

, 2012
A general quantum limit to the sensitivity of particle position measurements is derived following the simple principle of the Heisenberg microscope. The value of this limit is calculated for particles in the Rayleigh and Mie scattering regimes, and with ...

Three-dimensional trapping and assembly of small particles with synchronized spherical acoustical vortices

, 2020
Three-dimensional harmless contactless manipulation and assembly of micro-objects and micro-organisms would open new horizons in microrobotics and microbiology, e.g. for microsystems assembly or tissue engineering. In our previous work [Gong and Baudoin,

Holographic aberration correction: optimising the stiffness of an optical trap deep in the sample [PDF]

, 2011
We investigate the effects of 1st order spherical aberration and defocus upon the stiffness of an optical trap tens of μm into the sample. We control both these aberrations with a spatial light modulator. The key to maintain optimum trap stiffness over a
