Abstract

The present invention provides a transistor optical tweezer, comprising: a first electrode; a second electrode; a phototransistor array provided between the first electrode and the second electrode, the phototransistors being physically separated from each other by first insulating components, and each phototransistor comprising a collector region, a base region, and a transmitting region that are supported by a substrate; the transmitting region of each phototransistor comprising at least two transmitting subregions, the transmitting subregions being physically separated at least partly by the base regions, and the at least two transmitting subregions having a common base region and collector region. The transistor structure implements an increased photogenerated current without modifying the light intensity of a light beam being shone or the size of a window of transistors, thus allowing the generation of an increased DEP force. In addition, compared with an undivided transmitting region, the presence of the multiple transmitting subregions allows the distribution of a nonuniform electric field generated due to illumination to be denser and more uniform, thus facilitating the manipulation of a micro-object.
