Abstract
A method and a device for identifying a single molecule, a method and a device for counting a single molecule and a system for processing a single molecule are provided. The method for identifying the single molecule includes inputting time sequence of an intensity of an spot; forming a line chart of time and intensity of the spot according to the time sequence, wherein the line chart consists of a plurality of line segments; dividing the line chart into a plurality of grids in an array, counting the number of the line segments and/or ends of the line segments in each grid; subjecting the divided line chart to a line erosion according to numbers corresponding to the grids to transform the divided line chart to a simplified image; subjecting the simplified image to run-length coding to indicate connected domains; calculating an area of each connected domain and determining that the connected domain corresponds to a single molecule if the area of the connected domain is greater than a first predetermined threshold. According to the method for identifying the single molecule, the line chart of the time sequence of the intensity of the spot is processed to transform into the image, which results in a quick identification for the single molecule and a high accuracy of the identification.
