Radiopaque hydrogel microspheres
Journal of Microencapsulation, 1989Spherical, 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
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.

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.

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.

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

Microspheres in cancer therapy
Indian Journal of Cancer, 2010Cancer 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.

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 ...

Development and Evaluation of Controlled-Release Diclofenac Microspheres and Tabletted Microspheres
Journal of Microencapsulation, 1994Diclofenac wax microspheres were prepared using the congealable dispersephase encapsulation method. Emulsifiers, glyceryl monostearate (GMS) and stearic acid, were added to improve the efficiency of emulsification. Microspheres containing either of the emulsifiers or both showed a high drug content (80-90%) and the particle size distribution was log ...

Naturwissenschaften, 1980
A systematic review of catalytic activities in thermal proteinoids and microspheres aggregated therefrom yields some new inferences on the origins and evolution of metabolism. Experiments suggest that, instead of being inert, protocells were already biochemically and cytophysically competent. The emergence and refinement of metabolism ab initio is thus
