Dynamical analysis of an optical rocking ratchet: Theory and experiment

, 2013
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 experimental results are presented. The studied system consists of a microscopic

Optical vortex trap for resonant confinement of metal nanoparticles [PDF]

, 2008
The confinement and controlled movement of metal nanoparticles and nanorods is an emergent area within optical micromanipulation. In this letter we experimentally realise a novel trapping geometry near the plasmon resonance using an annular light field ...

Development of an in-process micro tensile tester and its application for measurement of the mechanical properties and adhesion forces of cells (Quantitative analysis of a cancer cell stiffness and adhesion forces)

Nihon Kikai Gakkai ronbunshu, 2020
The cells in living tissue change not only their proliferation and motility, but also their mechanical properties in response to external mechanical stimuli. The mechanical properties of the cells and their adhesion strength with the extracellular matrix

Relationship between the Young’s Moduli of Whole Microcapsules and Their Shell Material Established by Micromanipulation Measurements Based on Diametric Compression between Two Parallel Surfaces and Numerical Modelling

Micromachines, 2023
Micromanipulation is a powerful technique to measure the mechanical properties of microparticles including microcapsules. For microparticles with a homogenous structure, their apparent Young’s modulus can be determined from the force versus displacement ...

Negative Optical Torque

, 2014
Maxwell noted that light carries angular momentum, and as such it can exert torques on material objects. This was subsequently proved by Beth in 1936.

Micromanipulation through Chemical Play [PDF]

Clinical Chemistry, 2013
Physicists have long struggled to understand the quirky material vanadium dioxide (VO2). At temperatures >67 °C this metal oxide acts as a conductor. Cool it to a moderate temperature, however, and VO2 quickly rearranges its interior structure to become an insulator. And we are talking quick: Some have estimated the transition to happen in a trillionth

Waveguide Photoactuators: Materials, Fabrication, and Applications

Advanced Robotics Research, EarlyView.
Waveguide photoactuators convert guided light into mechanical motion. Their tethered‐flexible design enables minimally invasive surgery and confined‐space robotics. This review aims to guide materials selection, device design, and system integration, accelerating the transition of waveguide photoactuators from laboratory prototypes to versatile ...
