Abstract: A single molecule detection method based on grating scanning recognition, in which a large number of capture beads are scattered on a bead retaining plate (or a detection chip). At least part of the capture beads are specifically bound with an analyte, and each analyte is bound with a luminescent substance. Grating ports of a grating detection device are used to scan the capture beads column by column from the capture beads arranged at one end. The number of the capture beads bound with a marker is synchronously counted. The capture beads on the whole bead retaining plate are scanned through transverse relative movement between the grating ports and the capture beads. The total number of analytes can be obtained after scanning is completed.
