    摘要: A method and apparatus are provided for aligning optical elements or microbeads, wherein each microbead has an elongated body with a code embedded therein along a longitudinal axis thereof to be read by a code reading device. The microbeads are aligned with a positioning device so the longitudinal axis of the microbeads is positioned in a fixed orientation relative to the code reading device. The microbeads are typically cylindrically shaped glass beads between 25 and 250 microns (μm) in diameter and between 100 and 500 μm long, and have a holographic code embedded in the central region of the bead, which is used to identify it from the rest of the beads in a batch of beads with many different chemical probes. A cross reference is used to determine which probe is attached to which bead, thus allowing the researcher to correlate the chemical content on each bead with the measured fluorescence signal. Because the code consists of a diffraction grating typically disposed along an axis, there is a particular alignment required between the incident readout laser beam and the readout detector in two of the three rotational axes. The third axis, rotation about the center axis of the cylinder, is azimuthally symmetric and therefore does not require alignment.

    摘要: An assay stick 7 includes a transparent reaction vessel or tube 14 having one or more microbeads 8 disposed therein. The microbeads 8 have a plurality of unique identification digital codes based on a diffraction grating 12 disposed therein that are detected when illuminated by incident light 24. The incident light 24 may be directed transversely onto the side or onto an end of the tube 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 disposed upon completion of the assay. Alternatively, the beads may be attached to a strip or planar surface. The encoded beads can also provide traceability, quality-control, and authenticity of each bead 8 to its source and/or to the chemistry on each bead 8. Also, the low sample volume of the assay stick allows for faster reactions and better sensitivity.
