This method for detecting a target particle comprises (a) a step for preparing a solution containing a target particle, a luminescent probe that binds to the target particle and a particle for separation and recovery, or containing the target particle bound to the luminescent probe, the luminescent probe and the particle for separation and recovery, and forming a complex composed of the target particle, the luminescent probe and the particle for separation and recovery in the solution, (b) a step for recovering the particle for separation and recovery from the solution by solid-liquid separation treatment following step (a) and preparing a sample solution containing the particle for separation and recovery, and (c) a step for calculating the number of molecules of the complex present in the sample solution according to a scanning molecule counting method, wherein the particles for separation and recovery bind to a complex composed of the target particles and the luminescent probe. |
