Sample plate and analyzing method

Kirsi Tappura (Inventor), Hannu Välimäki (Inventor)

Research output: PatentPatent


A sample plate (1) and an analysing method, wherein the sample plate (1) comprises a substrate (2), at least one sensor site (5) on a first surface (3) of the substrate (2) and at least one optical element (6) on a second surface (4) of the substrate (2). The sample plate (1) is further provided with a waveguide (7) on the second surface (4) for guiding an excitation signal to interact with the at least one sensor site (5). The method comprises bringing the sample in contact with at least one sensor site (5), exciting the sensor site (5) in order to obtain an emitted signal, and selectively collecting the emitted signal by means of at least one optical element (6) and utilizing a supercritical angle fluorescence method; and detecting the collected emitted signals by a detector. In the method, the sensor site (5) is excited by means of an evanescent field generated by the excitation signal propagating in a waveguide (7).
