Abstract:
A device and method for determining substances within a fluid stream through the employment of light projected therethrough or emitted by the substances energized in the fluid stream. The device features a fluid chamber through which light, at known wavelengths, is projected through the fluid stream to a light sensor. The substances in the fluid stream are determinable by ascertaining which respective light wavelengths emitted by the light emitter do not contact the light sensor because they are absorbed by respective substances in the fluid stream. Alternatively, the substances in the fluid stream can be energized to emit light in wavelengths which can be ascertained as emitted by individual substances.
Abstract:
Disclosed is a composite particle for use in a marking that is suitable for identification/authentication purposes. The particle comprises at least one superparamagnetic portion and at least one thermoluminescent portion coated with an thermoisolating portion. Optionally also a thermoconductive portion between the superparamagnetic and thermoluminscent portions.
Abstract:
La présente invention concerne un procédé de génération de lumière par électrochimiluminescence (généralement désignée par l'acronyme ECL), dans lequel on induit une émission ECL par un ensemble de particules (notamment micro-ou nanométriques) électriquement conductrices en solution. La présente invention concerne également l'utilisation d'un tel procédé pour l'immunodosage d'une molécule présente dans lemilieu solvant.
Abstract:
Computing systems, computer-readable media and methods are disclosed. In the computing system, an image capture device captures an image of a protein array including spots of predetermined proteins, wherein some of the spots have bound to a biological material having individual-specific antibodies to form immune complexes and some of the immune complexes have interacted with a detection agent to generate a visible image therefrom. The computing system may be operably coupled to the image capture device and processes the captured image of the protein array to determine control locations of a plurality of control spots in known locations on the protein array. The computing system also extrapolates expected locations of all other spots on the protein array from the control locations.
