A contactless selection device, a light sensing structure thereof, and a biological particle selection apparatus are provided. The light sensing structure includes a substrate, an insulating layer, an electrode layer, and a photoelectric layer, the latter two of which are respectively formed on two opposite sides of the substrate. The photoelectric layer includes a plurality of collector regions, a plurality of base regions respectively formed in the collector regions, and a plurality of emitter regions that are respectively formed in the base regions. Each of the emitter regions includes a plurality of emitter pads formed in the corresponding base region. Each of the base regions, the corresponding collector region, and the corresponding emitter region are jointly formed as a vertical transistor. The insulating layer covers and separates the vertical transistors and an end of each of the emitter pads is exposed from the insulating layer.
