Title:
OPTICAL TWEEZER APPARATUS BASED ON PHOTOTRANSISTORS HAVING EQUAL-DENSITY ARRANGEMENT IN OBLIQUE DIRECTION, AND MICROFLUIDIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/125489
Kind Code:
A2
Abstract:
The invention provides: a first electrode; a second electrode; a phototransistor array arranged between the first electrode and the second electrode, the phototransistor array comprising a plurality of bipolar phototransistors, and each of the phototransistors being physically isolated from one another via an insulating element; the plurality of phototransistors are regularly arranged, and are arranged at a first interval in a transverse direction and at a second interval in a longitudinal direction; transistors which are adjacent in the longitudinal direction are staggered in the transverse direction, and a line connecting center points of the adjacent transistors is oblique; transistors along the oblique direction are arranged at a third interval, and the third interval is substantially equal to the first interval or to the second interval. Transistor optical tweezers provided in the present invention have a transistor array arrangement density in a transverse direction or longitudinal direction which is substantially equal to the arrangement density thereof in an oblique direction, allowing for generating a balanced DEP force, and for more convenient and precise operations regarding cells and other micro-scale objects.
