Optical tweezers are powerful tools for high resolution study of surface properties. Such experiments are traditionally performed by studying the active or the Brownian fluctuation of trapped particles in the X, Y and Z directions. Here we find that employing the fourth dimension, rotation, allows for sensitive and fast probing of the surface, and happen when birefringent microparticles are applied with circularly polarized light, thus called the rotational optical tweezers. When the trapped… 

Pitch-rotational manipulation of single cells and particles using single-beam thermo-optical tweezers.

Hexagonal-shaped upconverting particles and single cells trapped close to a gold-coated glass cover slip in a sample chamber are used to generate complete 360 degree and continuous pitch motion even with a single optical tweezer beam.

Generation of active motion from optically trapped upconverting nanoparticles

Optical trapping of janus particles has turned out to be complicated due to lack of control on the direction of orientation. Here we use an alternative strategy, where we optically trap a NaYF4:Yb,Er

Detection of sub-degree angular fluctuations of the local cell membrane slope using optical tweezers.

It is found that one can extract parameters like bending rigidity directly from the coefficient of the power spectrum particularly at high frequencies, instead of being convoluted with other parameters, thereby improving the accuracy of estimation.

Continuous rotational motion in birefringent particles using two near-orthogonally polarized optical tweezers beams at different wavelengths with low ellipticity

Continuous yaw (in-plane) rotation of an optically trapped birefringent particle is conventionally achieved by illuminating with light of high ellipticity. This ellipticity has to be high enough to

Validity of cylindrical approximation for spherical birefringent microparticles in rotational optical tweezers

Rotational manipulation of microscopic birefringent particles has conventionally been done by manoeuvring the polarization of the trapping light in optical tweezers. The torque on the particle is a

Direct detection of cell membrane slope fluctuations upon adding Latrunculin B using optical tweezers and single probe particle

The cell membrane has fluctuations due to thermal and athermal sources. That causes the membrane to flicker. Conventionally, only the normal (perpendicular to the membrane) fluctuations are studied

Pitch rotation of hexagonal microparticle using single beam thermo-optical tweezers

Single beam thermo-optical tweezers has been used for rotating particles continuously by 360o in pitch sense. The particle is rotated by placing it in a sample chamber with a thin layer of gold

Measurement of viscoelastic properties of the cellular cytoplasm using optically trapped Brownian probes

A recent extension of Jeffery’s model of viscoelasticity in the microscopic domain is employed to fit the passive motional power spectra of micrometer-sized optically trapped particles embedded in a visCoelastic medium to bypass the dependence on probe size by relying upon small thermal displacements.

Trapped in Out-of-Equilibrium Stationary State: Hot Brownian Motion in Optically Trapped Upconverting Nanoparticles

Upconverting nanoparticles typically absorb low frequency radiation and emit at higher frequencies relying upon multiphoton processes. One such type of particle is NaYF4:Yb,Er, which absorbs at 975

Towards Stirling engine from a single up-converting particle confined in an optical trap at pump-wavelength exhibiting Hot Brownian Motion

Up-converting particles (UCP) absorb wavelengths in IR region and emit light in visible region by multiphoton absorption process. When optically trapped with 975 nm laser, these particles show active



Surface forces and drag coefficients of microspheres near a plane surface measured with optical tweezers.

It is shown that the displacement sensitivity of the tweezers is modulated by a standing light wave between the microsphere and the surface, and the data suggest that microspheres can experience attractive and/or repulsive forces close to surfaces.

Surface imaging beyond the diffraction limit with optically trapped spheres.

It is demonstrated that, by the combination of a time-shared twin-optical trap and nanometre-precise three-dimensional interferometric particle tracking, both reliable height profiling and surface imaging are possible with a spatial resolution below the diffraction limit.

Photonic Force Microscopy: A New Tool Providing New Methods to Study Membranes at the Molecular Level

For the first time, the diffusion coefficient measured locally in the plasma membrane of an intact cell agreed well with previous measurements for lipid model membranes, thus providing new ways to characterize membrane structures with unknown properties, such as lipid rafts.

Optical alignment and spinning of laser-trapped microscopic particles

Light-induced rotation of absorbing microscopic particles by transfer of angular momentum from light to the material raises the possibility of optically driven micromachines. The phenomenon has been

A set of calibration approaches for the optical torque wrench is described and implemented, including methods that have direct analogs in linear optical tweezers as well as introducing others that are specifically developed for the angular variables.

Determination of pitch rotation in a spherical birefringent microparticle

Rotational motion of a three dimensional spherical microscopic object can happen either in pitch, yaw or roll fashion. Among these, the yaw motion has been conventionally studied using the intensity

Brownian microparticles diffusing in optical potential-energy landscapes constitute a generic test bed for nonequilibrium statistical thermodynamics and have been used to emulate a wide variety of

Comparison of Faxén's correction for a microsphere translating or rotating near a surface.

It is found that the corrections for the rotational motion is only required for particle-wall separations an order of magnitude shorter than that for the translational cases, and the hitherto unmeasured rotational equivalent is reported.

Small cantilevers for force spectroscopy of single molecules

We have used a simple process to fabricate small rectangular cantilevers out of silicon nitride. They have lengths of 9–50 μm, widths of 3–5 μm, and thicknesses of 86 and 102 nm. We have added
