Tweezer manipulation system based on transduction device, preparation method, and manipulation method

Abstract

Provided are a tweezer manipulation system based on a transduction device, a preparation method, and a manipulation method, relating to the field of physical field manipulation. The tweezer manipulation system comprises a transduction device and an external field control device. The transduction device generates a spatially gradient electric field under remote excitation by ultrasonic, magnetic, and optical fields generated by the external field control device, thereby achieving non-contact and non-destructive manipulation of objects in solid, liquid and gaseous phases on the basis of the dielectrophoretic force exerted on the objects under the gradient electric field. The tweezer manipulation system allows for coordinated regulation of the magnitude and direction of the dielectrophoretic force by means of the transduction device and the external field control device, enables manipulation of objects across size scales ranging from nanometers to centimeters, achieves precise manipulation of both single and multiple objects, and has huge application potential in the fields of chemical reactions, biochemical sensing, cell manipulation, and micro / nanorobots, etc.
