The Use of Tracers in Transport Studies

2020
Tracers can be tagged to specific molecules of biological interest and used to follow the fate of the latter within a cell. The use of the ultrastructural tracers in permeability studies assumes a thorough characterization of their molecular weight, size, shape, net electrical charge, and chemistry.

A tracer technique for cratering studies

Journal of Geophysical Research, 1965
Abstract : A method is outlined whereby marker cans are used in colored sand columns to measure the ejecta and ground movements in the vicinity of a crater from a 20-ton surface burst TNT detonation. It is shown that the use of marker cans greatly increases the data obtained from the sand columns, with comparatively little increase in the cost of the ...

Radioactive tracer studies of monolayers

Journal of Colloid Science, 1958
Abstract The composition of built-up calcium stearate stearic acid layers has been studied with Ca45. The results diverge from those obtained by conventional chemical analysis of the floating layers (“H-layers”), from which the built-up layers were formed.

Parkinson’s disease and PET tracer studies

1988
Although the cause of Parkinson's disease is still unknown it has become clear that dopaminergic cell loss in the substantia nigra is a prominent feature of the disease. The study of cerebral dopaminergic function-dominated by the nigrostriatal system-in relation to motor abnormalities and their response to treatment has been in the centre of research ...
