Reversibility in nonequilibrium trajectories of an optically trapped particle.
The fluctuation theorem (FT) describes how a system's thermodynamic irreversibility develops in time from a completely thermodynamically reversible system at short observation times, to a thermodynamically irreversible one at infinitely long times. In this paper, we present a general definition of the dissipation function Omega(t), the quantitative argument in the fluctuation theorem (FT), that...
متن کاملLocalized plasmonic structured illumination microscopy with an optically trapped microlens.
Localized plasmonic structured illumination microscopy (LPSIM) is a recently developed super resolution technique that demonstrates immense potential via arrays of localized plasmonic antennas. Microlens microscopy represents another distinct approach for improving resolution by introducing a spherical lens with a large refractive index to boost the effective numerical aperture of the imaging s...
متن کاملSpatially-resolved rotational microrheology with an optically-trapped sphere
We have developed amicrorheometer, based on optical tweezers, in which hydrodynamic coupling between the probe and fluid boundaries is dramatically reduced relative to existing microrheometers. Rotational Brownianmotion of a birefringentmicrosphere within an angular optical trap is observed bymeasuring the polarisation shifts of transmitted light. Data gathered in this manner, in the strongly v...
متن کاملProbing the dynamics of an optically trapped particle by phase sensitive back focal plane interferometry.
The dynamics of an optically trapped particle are often determined by measuring intensity shifts of the back-scattered light from the particle using position sensitive detectors. We present a technique which measures the phase of the back-scattered light using balanced detection in an external Mach-Zehnder interferometer scheme where we separate out and beat the scattered light from the particl...
متن کاملThermal Scanning at the Cellular Level by an Optically Trapped Upconverting Fluorescent Particle.
3D optical manipulation of a thermal-sensing upconverting particle allows for the determination of the extension of the thermal gradient created in the surroundings of a plasmonic-mediated photothermal-treated HeLa cancer cell.
