Abstract
A contactless selection device, a light triggering structure thereof, and a biological particle selection apparatus are provided. The light triggering structure includes a first substrate, a first electrode layer formed on the first substrate, a photodiode layer formed on the first electrode layer, and an insulating layer that covers the photodiode layer. The photodiode layer has a thickness within a range from 1 μm to 3 μm, and includes a first doped layer, an I-type layer, and a second doped layer, which are sequentially stacked from the first electrode layer. The second doped layer includes a plurality of triggering pads spaced apart from each other. Each of the triggering pads has a width within a range from 3 μm to 7 μm, and a distance between any two of the triggering pads adjacent to each other is less than or equal to 2 μm.
