Utilisation de cristaux liquides thermochromiques dans le cadre de methodes diagnostiques par reflectometrie

Use of thermochromic liquid crystals in reflectometry based diagnostic methods

Abstract

Disclosed is a method for improving the accuracy of temperature sensitive diagnostic assays which are carried out using reflectance spectrometers to detect color changes in a solid test system which has been contacted with a fluid test system suspected of containing an analyte whose presence and/or concentration is being sought. The improvement involves determining the temperature of the solid test material by measuring the reflectance of a thermochromic liquid crystal in close proximity to the solid test material and correcting the result of the assay for a change in temperature from a pre-selected nominal temperature.
