Abstract:
1. A sample analysis disc comprising: a disc surface; a track area having concave sections and convex sections formed alternately on the disc surface; and labeled beads immobilized to the track area, each labeled bead having a biopolymer bound thereto, wherein only one of the labeled beads is allowed to be filled in each concave section, and wherein a ratio of the diameter of each labeled bead to the width of each concave section is equal to or larger than 0.6, but smaller than 1, so that only one of the labeled beads is allowed to be filled in each concave section, and a ratio of the width of each concave section to an interval between two adjacent concave sections in a direction of a radius of the sample analysis is equal to or larger than 0.65, wherein each concave section has a first edge section and an opposite second edge section in the direction of the radius, the first edge section being closer or farther than the second edge section to or from a center of the sample analysis disc in the direction of the radius, the interval being a distance between the first edge section of each concave section and the first edge section of a concave section next to each concave section in the direction of the radius.
