Understanding and improving axial detection in optical tweezers based on the interference of forward- and backward- scattered light
Isaac Pérez Castillo, Simon Leturcq, Sylvain Domitin +3
Fast and accurate 3D position detection in optical tweezers (OT) is essential for quantitatively monitoring subtle variations in the mechanical properties of microscopic systems ra…
Transition path time over a barrier of a colloidal particle in a viscoelastic bath
Brandon R. Ferrer, Alejandro V. Arzola, Denis Boyer +1
We experimentally study the statistics of the transition path time taken by a submicron bead to successfully traverse an energy barrier created by two optical tweezers in two proto…
Tutorial for the growth and development of Myxococcus xanthus as a Model System at the Intersection of Biology and Physics
Jesus Manuel Antúnez Domínguez, Laura Pérez García, Natsuko Rivera-Yoshida +8
Myxococcus xanthus is a unicellular organism whose cells possess the ability to move and communicate, leading to the emergence of complex collective properties and behaviours. This…
Shaping the angular spectrum of a Bessel beam to enhance light transfer through dynamic strongly-scattering media
Dennis Scheidt, Alejandro Vasquez Arzola, Pedro Antonio Quinto-Su
We prepare a quasi-non-diffracting Bessel beam defined within an annular angular spectrum with a spatial light modulator. The beam propagates though a strongly scattering media and…
Optimal calibration of optical tweezers with arbitrary integration time and sampling frequencies -- A general framework
Laura Pérez-Garcéa, Martin Selin, Antonio Ciarlo +6
Optical tweezers (OT) have become an essential technique in several fields of physics, chemistry, and biology as precise micromanipulation tools and microscopic force transducers.…
Roadmap for Optical Tweezers
Giovanni Volpe, Onofrio M. Maragò, Halina Rubinzstein-Dunlop +80
Optical tweezers are tools made of light that enable contactless pushing, trapping, and manipulation of objects ranging from atoms to space light sails. Since the pioneering work b…
Enhancing Near-Field Optical Tweezers by Spin-to-Orbital Angular Momentum Conversion
Edgar Alonso Guzmán, Alejandro V. Arzola
Near-field patterns of light provide a way to optically trap, deliver and sort single nanoscopic particles in a wide variety of applications in nanophotonics, microbiology and nano…
Fluid viscoelasticity triggers fast transitions of a Brownian particle in a double well optical potential
Brandon R. Ferrer, Juan Ruben Gomez-Solano, Alejandro V. Arzola
Thermally activated transitions are ubiquitous in nature, occurring in complex environments which are typically conceived as ideal viscous fluids. We report the first direct observ…
Optical Tweezers: A Comprehensive Tutorial from Calibration to Applications
Jan Gieseler, Juan Ruben Gomez-Solano, Alessandro Magazzù +9
Since their invention in 1986 by Arthur Ashkin and colleagues, optical tweezers have become an essential tool in several fields of physics, spectroscopy, biology, nanotechnology, a…
Light control through a nonlinear lensing effect in a colloid of biosynthesized Gold Nanoparticles
A. Balbuena Ortega, E. Brambilia, V. López Gayou +5
Biosynthesis of four samples of colloidal suspensions of gold nanoparticles is achieved using hydroalcoholic extract and three different separated compounds of the plant Bacopa pro…
Stationary superstatistics distributions of trapped run-and-tumble particles
Francisco J. Sevilla, Alejandro V. Arzola, Enrique Puga Cital
We present an analysis of the stationary distributions of run-and-tumble particles trapped in external potentials in terms of a thermophoretic potential, that emerges when trapped…
Omnidirectional Transport in Fully Reconfigurable Two Dimensional Optical Ratchets
Alejandro V. Arzola, Mario Villasante-Barahona, Karen Volke-Sepúlveda +2
A fully reconfigurable two-dimensional (2D) rocking ratchet system created with holographic optical micromanipulation is presented. We can generate optical potentials with the geom…
Dynamical analysis of an optical rocking ratchet: Theory and experiment
Alejandro V. Arzola, Karen Volke-Sepúlveda, José L. Mateos
A thorough analysis of the dynamics in a deterministic optical rocking ratchet (introduced in A. V. Arzola et al., Phys. Rev. Lett. 106, 168104 (2011)) and a comparison with experi…
Experimental Control of Transport and Current Reversals in a Deterministic Optical Rocking Ratchet
Alejandro V. Arzola, Karen Volke-Sepúlveda, José L. Mateos
We present an experimental demonstration of a deterministic optical rocking ratchet. A periodic and asymmetric light pattern is created to interact with dielectric microparticles i…
