Abstract:
The invention relates to an optical sensor (1) for determining particle and/or dye concentrations in liquid or gaseous media and to a method for operating the same. The optical sensor (1) comprises at least one measuring head. The measuring head consists of an emitter unit (2) with a semiconductor emitting element (9), which emits visible emission light beams (8), and with a receiver unit (3) with a semiconductor receiving element (10). The portion of the emission light beams (8), which pass through an absorption section containing liquid or gaseous medium, is guided onto the receiving element (10). An evaluating unit (6) is coupled to the measuring head via electric leads (4, 4′), and the received signals, which are present at the output of the semiconductor receiving element (10), are evaluated inside said evaluating unit in order to determine the particle or die concentration.
Abstract:
The invention provides methods for the sensitive detection of cardiac troponin. Such methods are used in diagnosis, prognosis, and determination of methods of treatment in conditions that involve release of cardiac troponin.
Abstract:
Disclosed herein is a method for improving the precision of a test result from an instrument with an optical system that detects a signal. The method comprises including in the instrument a normalization target disposed directly or indirectly in the optical path of the optical system. Also disclosed are instruments comprising a normalization target, and systems comprising such an instrument and a test device that receives a sample suspected of containing an analyte.

Abstract:
A fluorescence observation apparatus according to an embodiment of the present technology includes a stage, an excitation section, and a spectroscopic imaging section. The stage is capable of supporting a fluorescently stained pathological specimen. The excitation section irradiates the pathological specimen on the stage with a plurality of line illuminations of different wavelengths, the plurality of line illuminations being a plurality of line illuminations situated on different axes and parallel to a certain-axis direction. The spectroscopic imaging section includes at least one imaging device capable of separately receiving pieces of fluorescence respectively excited with the plurality of line illuminations.
Abstract:
Provided is an information processing apparatus (100) including: an image acquiring unit (112) that acquires captured image information of a sample (20) dyed with a fluorescent dye reagent (10), an information acquiring unit (111) that acquires information related to the fluorescent dye reagent (10), a correcting unit (131) that corrects the luminance of the captured image information using a fluorescence fading coefficient that represents the rapidness at which the fluorescence intensity of the fluorescent dye reagent (10) drops, the fluorescence fading coefficient being included in the fluorescent dye reagent (10), and a calculating unit (132) that calculates information corresponding to fluorescent molecules in the captured image information, using the corrected luminance.
