A spatial refractive index sensor using whispering gallery modes in an optically trapped microsphere [PDF]
We propose the use of an optically trapped, dye doped polystyrene microsphere for spatial probing of the refractive index at any position in a fluid. We demonstrate the use of the dye embedded in the microsphere as an internal broadband excitation source,

A Self-Assembled Microlensing Rotational Probe [PDF]
A technique to measure microscopic rotational motion is presented. When a small fluorescent polystyrene microsphere is attached to a larger polystyrene microsphere, the larger sphere acts as a lens for the smaller microsphere and provides an optical ...

Polymeric microsphere injection in large pore-size porous media
High water-cut has become a worldwide challenge for oil production. It requires extensive efforts to process and dispose. This entails expanding water handling facilities and incurring high power consumption costs.

Recoiling DNA Molecule: Simulation & Experiment [PDF]
Single molecule DNA experiments often generate data from force versus extension measurements involving the tethering of a microsphere to one end of a single DNA molecule while the other is attached to a substrate.

Coaxial Atomic Force Microscope Tweezers [PDF]
We demonstrate coaxial atomic force microscope (AFM) tweezers that can trap and place small objects using dielectrophoresis (DEP). An attractive force is generated at the tip of a coaxial AFM probe by applying a radio frequency voltage between the center

Atomic entanglement near a realistic microsphere [PDF]
We study a scheme for entangling two-level atoms located close to the surface of a dielectric microsphere. The effect is based on medium-assisted spontaneous decay, rigorously taking into account dispersive and absorptive properties of the microsphere ...

Experimental Study on Expansion Characteristics of Core-Shell and Polymeric Microspheres
Traditional polymeric microsphere has several technical advantages in enhancing oil recovery. Nevertheless, its performance in some field application is unsatisfactory due to limited blockage strength.

Coupling of ultrathin tapered fibers with high-Q microsphere resonators at cryogenic temperatures and observation of phase-shift transition from undercoupling to overcoupling [PDF]
We cooled ultrathin tapered fibers to cryogenic temperatures and controllably coupled them with high-Q microsphere resonators at a wavelength close to the optical transition of diamond nitrogen vacancy centers.

High-Q bismuth silicate nonlinear glass microsphere resonators [PDF]
The fabrication and characterization of a bismuth-silicate glass microsphere resonator has been demonstrated. At wavelengths near 1550 nm, high-modes can be efficiently excited in a 179 µm diameter bismuth-silicate glass microsphere via evanescent ...
