Whispering gallery mode microsphere resonator with microsphere-microsphere coupling

Optical Fiber Technology, 2018
Abstract We demonstrate a new type of whispering gallery mode microsphere resonator with microsphere-microsphere coupling. The device is based on two cascaded microspheres glued on a single mode fiber tip. The incident light from the fiber core diverges in the first microsphere and part of light is coupled to the surface of the second microsphere ...

Glass Microspherical Lasers

Advances in Science and Technology, 2008
We report experimental results obtained in our laboratories in the development of Er3+- doped glass microspherical cavities for the fabrication of compact and low threshold laser sources at 1.55 μm. We investigate three different approaches in order to fabricate the microspheres including direct melting of Er3+-doped glass powders, coating of silica ...

Electrorotation of Metallic Microspheres

Langmuir, 2011
Electrorotation (ER) experiments of gold-coated micrometer-sized spheres suspended in an electrolyte are presented for three different ionic conductivities over the frequency range of 100 Hz to 40 MHz. The direction of rotation was observed to be counter-field (opposite to the rotating field vector) with a single rotation peak.

Microsphere: A Review

Research Journal of Topical and Cosmetic Sciences, 2016
Microspheres are characteristically free flowing powders consisting of proteins or synthetic polymers having a particle size ranging from 1-1000 μm. The range of Techniques for the preparation of microspheres offers a variety of opportunities to control aspects of drug administration and enhance the therapeutic efficacy of a given drug.

Microspheres in cancer therapy

Indian Journal of Cancer, 2010
Cancer microsphere technology is the latest trend in cancer therapy. It helps the pharmacist to formulate the product with maximum therapeutic value and minimum or negligible range side effects. Cancer is a disease in which the abnormal cells are quite similar to the normal cells, with just minute genetic or functional change.

Radiopaque hydrogel microspheres

Journal of Microencapsulation, 1989
Spherical, hydrophilic microspheres prepared from crosslinked poly(methyl methacrylate) (PMMA) by alkaline hydrolysis have been made radiopaque by impregnating with barium sulphate by the precipitation technique. Microspheres having carboxyl functions as their alkali metal salt were swollen in sodium sulphate solution and barium sulphate entrapment was

Polyacrolein microspheres as immunoreagents

Journal of Immunological Methods, 1983
Polyacrolein microspheres were prepared by radiation polymerization of acrolein in the absence of emulsifying or stabilizing agent. The microspheres had functional surface aldehyde groups permitting covalent binding with antibody in 1 step. The particle size of the microspheres varied with polymerization conditions, especially irradiation temperature ...
