Micro-Dumbbells—A Versatile Tool for Optical Tweezers
Micromachines, 2018 Manipulation of micro- and nano-sized objects with optical tweezers is a well-established, albeit still evolving technique. While many objects can be trapped directly with focused laser beam(s), for some applications indirect manipulation with tweezers ...

Holographic tracking and sizing of optically trapped microprobes in diamond anvil cells [PDF]
, 2016 We demonstrate that Digital Holographic Microscopy can be used for accurate 3D tracking and sizing of a colloidal probe trapped in a diamond anvil cell (DAC).

Expanding the toolbox for nanoparticle trapping and spectroscopy with holographic optical tweezers [PDF]
, 2012 We have developed a workstation based on holographic tweezers to optically trap, move and characterize metal nanoparticles. Our advanced darkfield imaging system allows us to simultaneously image and take spectra of single trapped metal nanoparticles. We

Composite Diffraction-Free Beam Formation Based on Iteratively Calculated Primitives
Micromachines, 2023 To form a diffraction-free beam with a complex structure, we propose to use a set of primitives calculated iteratively for the ring spatial spectrum. We also optimized the complex transmission function of the diffractive optical elements (DOEs), which ...

Compliant rolling-contact architected materials for shape reconfigurability
Nature Communications, 2018 The authors introduce a compliant rolling-contact architected material as a class of shape reconfigurable mechanical metamaterial. They also devise an approach that combines two photon stereolithography and scanning holographic optical tweezers, which ...

Simulation of superresolution holography for optical tweezers [PDF]
, 2008 Optical tweezers manipulate microscopic particles using foci of light beams. Their performance is therefore limited by diffraction. Using computer simulations of a model system, we investigate the application of superresolution holography for two ...

Classical and Quantum Gases on a Semiregular Mesh
Applied Sciences, 2021 The main objective of a statistical mechanical calculation is drawing the phase diagram of a many-body system. In this respect, discrete systems offer the clear advantage over continuum systems of an easier enumeration of microstates, though at the cost ...
