Abstract: A cellular mechanical property measurement and sorting method comprises: cells to be sorted being arranged in a straight line after passing through a standing wave acoustic field generated by a first interdigital transducer; the cells flowing through a focused acoustic field generated by a second interdigital transducer, and the focused acoustic field generating a radiation force on the cells, such that the cells are deformed; performing calculation according to information of the radiation force and deformation, so as to obtain elastic moduli of the cells; determining the positions of the cells, and selectively driving, with designed delay time, interdigital transducers in a cell sorting unit according to the moving speeds of the cells and the distances between the cells and the sorting unit, and triggering, according to the elastic moduli, a corresponding interdigital transducer to generate a planar acoustic field, so as to sort the cells.
