OPTICAL MEASUREMENT METHOD FOR MOLECULAR DETECTION USING RELAXATION MEASUREMENTS AT OPTICALLY ANISOTROPIC NANOPARTICLES

摘要

Optical measurement methods are disclosed that are suitable for determining the relaxation behavior of nanoparticles (62) dispersed in a solution, said nanoparticles having optically anisotropic properties and being alignable by an external stimulus, such as an electrical or magnetic field (61). The aim of the invention is the optical detection of certain molecules that can bind specifically to the surface of the nanoparticle, and thus modify the relaxation behavior of the nanoparticles, and devices for implementing the methods.
