Method and device for the quantitative measurement has a high rate of targets biomolecular presented on or in a support for biological analysis.

摘要

The present invention relates to a device and a process for the quantitative measurement at a high rate of targets biomolecular to the surface or in the thickness of a support plane of analysis biologique.le process according to the invention comprises the following steps: a) is focused and superimposed on each measurement point of this support at least two laser beams (f) by simultaneous crossings of these beams, in order to extract a hot plasma confined (p) comprising a chemical element to quantify present in the targets and another chemical exogenous to the targets and present in a known quantity on this support, b) it detects and analysis for each measurement point, the luminous lines of transmission of each plasma, which correspond to the element to be quantified and to the exogenous element, by measuring the intensity of these lines, puisc) is determined via a prior calibration of the lines of the element to quantify establish a correlation between the intensities of the lines which are adapted to this element and the concentrations of the latter in the mixture; in proportions known to the element to be quantified and the exogenous element, here concentration in each measurement point of the element to quantify.
