Figure 3From: Label-free electrical quantification of the dielectrophoretic response of DNATime course of capacitance for a typical DEP experiment. Capacitance of an aqueous solution of 18 nM pBluescript DNA with a DEP excitation of 1 MHz and 4VRMS. The duty cycle of the modulated signal was varied from 0.1% ("0") to 100% ("1.0"). The magnified view shows the change between 8 s DEP ("d") application and 2 s measurement ("m").Back to article page
