    摘要: A reflection-mode photoacoustic endoscope includes a light source configured to emit a light pulse, a signal detection or transmission unit configured to detect or emit an ultrasonic pulse, and a rotatable reflector. The rotatable reflector is configured to reflect at least one of the light pulse and the ultrasonic pulse into a target area of an object, and reflect a response signal to the signal detection unit. The response signal is one of a photoacoustic wave generated by the object responsive to the light pulse and an ultrasonic pulse echo generated by the object responsive to the ultrasonic pulse.

    摘要: A method for sorting cells in a biological sample comprising a first type of cells and a second type of cells may comprise introducing the biological sample into a chamber comprising a first surface and a second surface, wherein the first surface is associated with a transparent electrode and the second surface is associated with a photoconductive portion of an electrode. The method may further comprise moving incident light and the photoconductive portion relative to one another so as to illuminate regions of the photoconductive portion and modulate an electric field in the chamber in proximity to the illuminated regions. The method may further comprise separating the first type of cells from the second type of cells in the chamber via dielectrophoretic movement of the first type of cells and the second type of cells caused by the modulated electric field, wherein a dielectrophoretic characteristic of at least one of the first type of cells and the second type of cells has been modified.
