A detecting device for detecting biological particles includes an optical system including an excitation light source, a filter and spectroscope group, a photomultiplier tube, and a charge-coupled device. The excitation light source illuminates the biological particles on a detecting carrier of the detecting device. A kind of target biological particles in the biological particles is excited to generate an emission light. The emission light enters the filter and spectroscope group to be separated into a first detecting light and a second detecting light. After the photomultiplier tube receives the first detecting light, the photomultiplier tube transmits a regional positioning signal to a processor of the detecting device. After the charge-coupled device receives the second detecting light, the charge-coupled device transmits an image signal to the processor. The processor obtains a precise location of the target biological particles based on the regional positioning signal and the image signal. A detecting method of the detecting device is also provided.
