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 ...

Norethisterone contraceptive microspheres

Journal of Steroid Biochemistry, 1987
Two formulations of polylactic and polyglycolic acid microcapsules containing 75 and 100 mg of NET respectively were studied for a 90-day period of anticipated contraceptive effect in two groups of five women. A 200 mg dose of NET preparation was also studied for a 180-day period of anticipated contraceptive effect in 19 women.

Compartmentalization in proteinoid microspheres

Biosystems, 1977
Proteinoid microspheres with stable internal compartments and internal structure are made from acidic proteinoid and basic proteinoid with calcium. The populations of microspheres are characterized by a wide diversity of structure. A model of primitive intracellular communication is suggested by the observed movement of internal particles between ...

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 ...

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

Metabolism of proteinoid microspheres

1986
The literature of metabolism in proteinoids and proteinoid microspheres is reviewed and criticized from a biochemical and experimental point of view. Closely related literature is also reviewed in order to understand the function of proteinoids and proteinoid microspheres. Proteinoids or proteinoid microspheres have many activities.

Diagnostic Microspheres: An Overview

Critical Reviews™ in Therapeutic Drug Carrier Systems, 2003
Diagnostic methods have become increasingly complex and frequently involve the use of agents that must meet the same approval criteria as drugs. The search for diagnostic contrast agents has spread from X-ray to other imaging modalities, especially to magnetic resonance imaging (MRI) and ultrasound.

Electrorotation of titanium microspheres

ELECTROPHORESIS, 2013
Electrorotation (ROT) data for solid titanium micrometer‐sized spheres in an electrolyte are presented for three different ionic conductivities, over the frequency range of 10 Hz to 100 kHz. The direction of rotation was found to be opposite to the direction of rotation of the electric field vector (counterfield electrorotation), with a single rotation

Polymeric Microspheres for Immunoresearce

Immunological Communications, 1984
New microspheres having functional aldehyde groups have been prepared by radiation polymerization of acrolein solution containing hydroxyethyl methacrylate and glutalardehyde. The size distribution in the microspheres was narrow and average particle diameter was 1 - 2 micron.

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.
