Microspheres for biomedical applications: preparation of reactive and labelled microspheres
Biomaterials, 1993This review describes the synthesis and physico-chemical properties of reactive and labelled microspheres useful for biomedical applications. Preparation of microspheres with specific functional groups, fluorescent species, radionuclides and magnetite particles (Fe2O3) are discussed. Physico-chemical properties of microspheres, including surface charge

Metabolism of proteinoid microspheres
1986The 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.

The stability of proteinoid microspheres
Biosystems, 1994Proteinoid microspheres are stable hollow spheres of diameter of the order of 5 microns. Their stability is discussed in terms of macroscopic energies. It is shown that bulk and surface energy contributions alone cannot lead to stable microspheres. If electrostatic energy, due to transmembrane voltage, is taken into account, stable hollow spheres are ...

Compartmentalization in proteinoid microspheres
Biosystems, 1977Proteinoid 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 ...

Electrorotation of titanium microspheres
ELECTROPHORESIS, 2013Electrorotation (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, 1984New 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.

Diagnostic Microspheres: An Overview
Critical Reviews in Therapeutic Drug Carrier Systems, 2003Diagnostic 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.

Thermoanalysis of microspheres
Thermochimica Acta, 1995Abstract This paper describes different cases in which using DSC allows us to obtain more information about the internal structure of microspheres, especially concerning the nature of the interaction between the polymer matrix and the encapsulated drug.

Norethisterone contraceptive microspheres
Journal of Steroid Biochemistry, 1987Two 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.

Synthesis of CuInS2 Microspheres using In2S3 Microspheres as Templates
Australian Journal of Chemistry, 2009CuInS2 microspheres have been prepared via a solvothermal route employing synthetic In2S3 microspheres as templates. X-ray diffraction analysis reveals that CuInS2 crystals assembled from In2S3 microsphere building blocks are tetragonal phase. Field emission scanning electron microscopy and transmission electron microscopy images show that the ...
