ASSAY STICK COMPRISING CODED MICROBEADS |
摘要 |
An assay stick 7 includes a transparent reaction vessel or tube 14 having on e or more microbeads 8 disposed therein. The microbeads 8 have a plurality of unique identification digital codes based on a diffraction grating 12 dispos ed therein that are detected when illuminated by incident light 24. The inciden t light 24 may be directed transversely onto the side or onto an end of the tu be 14 with a narrow band (single wavelength) or multiple wavelength source, in which case the code is represented by a spatial distribution of light or a wavelength spectrum, respectively. The assay stick 7 may be reused or dispos ed upon completion of the assay. Instead of beads, cells or molecules may be spotted or grown directly on the tube.
