摘要:Abstract(#br)The axial deviation of the trapped particle in the lateral trap stiffness calibration and the maximal trapping force measurement has been reported, but has not yet been extensively analyzed in the literature. Due to the importance of the trapping force calibration in...

摘要:... In order to further develop this non-invasive approach as a microfluidic particle manipulation tool of high precision, the trapping force needs to be calibrated to a known force, i.e., viscous drag force arising from the fluid flow in the channel. However, few calibration ...

摘要:Abstract(#br)Based on an optical trapping system with a single-lensed fiber probe inserted at an angle, the sub-picoNewton trapping force acting on a yeast cell as a function of the displacement is measured experimentally by the static and dynamic methods, respectively, whose mea...

摘要:Abstract(#br)Dependence of optical trapping force on the trap depth is examined by calculating the intensity distribution of light focused through two media with different refractive indices. The optical trapping forces on the microsphere in the ray optics regime were measured as...

摘要:Laser cooling and magneto-optical trapping of molecules typically involves multiple transitions driven by several laser frequencies. We analyze how magneto-optical trapping forces depend on the angular momenta, F l and F u, and the g -factors, g l...

摘要:Abstract(#br)Optical trapping forces exerted by a focused Bessel-Gaussian correlated Schell-model (BGCSM) beam on Rayleigh dielectric spheres with different refractive indices are analyzed. The dependence of radiation forces on the transverse coherence width δ 0 , the coher...

摘要:Abstract(#br)We calculate the trapping forces exerted by a highly focused Bessel-Gaussian beam on a double-layered sphere by means of vector diffraction integral, T-matrix method and Maxwell stress tensor integral. The Bessel-Gaussian beam is azimuthally polarized. Numerical resu...

摘要:The dramatic influence of optical Kerr effect on the nature of trapping force/potential under pulsed excitation has recently been explored, particularly in the context of trapping of dielectric nanoparticles (Devi and De 2016 Opt. Express 24 21485–96, Devi and De 2017 Phys....

摘要:Abstract(#br)Optical trapping, where microscopic particles are trapped and manipulated by light is a powerful and widespread technique, with the single-beam gradient trap (also known as optical tweezers) in use for a large number of biological and other applications. The forces a...

摘要:Abstract(#br)Starting from the classical Boltzmann distribution, we obtain the ion density distribution in the limit of either high temperature/low density (Coulomb interaction energy much less than ion kinetic energy) or low temperature/high density (kinetic energy much less than Coulomb interaction energy), and the trapping force...
