Figure 4From: Label-free electrical quantification of the dielectrophoretic response of DNACapacitance change as a function of DEP field duty cycle. Data of Fig. 3 are presented as a function of the duty cycle of the dielectrophoresis field. pBluescript DNA concentration was 18 nM. Dielectrophoretic excitation was at a frequency of 1 MHz with a voltage of 4VRMS.Back to article page
