A Self-Assembled Microlensing Rotational Probe [PDF]

open access: yes, 1998
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 ...

Microsphere probe: combining microsphere-assisted microscopy with AFM

open access: yesOptics Express, 2023
In recent years, microsphere-assisted microscopy (MAM) and atomic force microscope (AFM) have been rapidly developed to meet the measurement needs of microstructures. However, the positioning of microspheres, the inability of AFM to touch the underlying sample through the transparent insulating layer, and the challenge of AFM fast positioning limit ...

Highly efficient hybrid fiber taper coupled microsphere laser [PDF]

open access: yes, 2001
A novel hybrid fiber taper is proposed and demonstrated as the coupler in a microsphere laser system. The pump wave and the laser emission, respectively, are more efficiently coupled to and from the sphere modes with this taper structure. A 980-nm pumped

Recoiling DNA Molecule: Simulation & Experiment [PDF]

open access: yes, 2002
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.

Locomotion of microspheres for super-resolution imaging [PDF]

open access: yes, 2013
Super-resolution imaging using sub-diffraction field localization by micron sized transparent beads (microspheres) was recently demonstrated [1]. Practical applications in microscopy require control over the positioning of the microspheres.

Microsphere Solid‐State Biolasers [PDF]

open access: yesAdvanced Optical Materials, 2017
Biolasers obtained from biomaterials are attracting a wealth of interest for their potential as future biosensors with enhanced sensitivity, and advanced cell tracking. Here, miniature biolasers are reported, which are formed by bovine serum albumin (BSA) protein and biosourced polysaccharides derived from land plants such as cellulose and pectin ...
