MODIFIED CELLS AS MULTIMODAL STANDARDS FOR CYTOMETRY AND SEPARATION

Inline classification of a biological specimen including mammalian cells can include generating an alternating current (AC) electrical stimulus to an electrode structure. The electrode structure can be electrically coupled with a flow cell. A response, elicited by the electrical stimulus, can be received when a model specimen class traverses the flow cell. Using the received response, a corresponding impedance parameter value can be determined, the value indicative of a specified biophysical characteristic corresponding to the model specimen class. The first impedance parameter can be translated to a value corresponding to the specified biophysical characteristic.
