Optics of microdroplets

Physics-Uspekhi, 2001
An overview of optical effects in micrometer-sized droplets is presented. The fundamentals of microdroplet optics are expounded. The scope of the analyzed phenomena includes enhancement of the spontaneous emission probability, laser generation, Raman light scattering, changes in the rates of physicochemical processes, and peculiarities of action on ...

Microdroplets-on-chip: A review

Proceedings of the Institution of Mechanical Engineers, Part H: Journal of Engineering in Medicine, 2019
Single-cell analysis serves as an important approach to study cell functions and interactions. Catering to the demand of Big Data Era, fast reactions for single cells and paralleled high-throughput analysis have become an urgent need. Microdroplet in microfluidics has advantages of modularity and integrity, as well as high throughput and sensitivity ...

A microdroplet-based shift register

Lab on a Chip, 2010
A microfluidic device is presented for the serial formation, storage and retrieval of water microdroplets in oil. The principle of operation is similar to that of an electronic shift register. Droplets, considered as units of information, can be arrayed and serially shifted within the device, allowing the controllable positioning of the emulsions and ...

Injection seeding of lasing in microdroplets

Optics Letters, 1997
Injection seeding of lasing has been achieved in both small (~20-mu; m radius) and larger (~35-mu; m radius) dye-doped microdroplets. Seeding is effective in enhancing the intensity from one lasing mode that normally occurs because of the droplet morphology.

Fluorescence Polarization Anisotropy in Microdroplets

The Journal of Physical Chemistry Letters, 2018
Chemical reactions can be greatly accelerated in microdroplets, but the factors that lead to acceleration are still being elucidated. Using rhodamine 6G (R6G) as a model compound, we studied the density distribution and fluorescence polarization anisotropy of this dye in water-in-oil microdroplets.

Phototaxis Flight of Microdroplets in a Laser

Physical Review Letters
Phototaxis phenomenon is fundamental and critical for optical manipulation of micro-objects. Here, we report the size-dependent negative or positive phototaxis behaviors for microdroplets containing interfacial energy absorber flying in a laser. The critical diameters for such negative-to-positive turnover are studied through both experiments and ...

Microdroplet Chemistry with Unactivated Droplets

Journal of the American Chemical Society
Microdroplet chemistry has attracted much attention owing to its ability to accelerate otherwise slow reactions and to trigger thermodynamically forbidden reactions. The cause of this unique behavior is the intrinsic properties of the droplets, such as the spontaneously generated electric field on the droplet surface. However, some have argued that the
