Summary For high-frequency measurements, the maximum reflected power for an RLC circuit occurs at the resonance frequency (fLC). An inductor-capacitor circuit has been built inside the atomic force microscope (AFM) driven by an RF source. The DNA is applied to the HOPG which creates a resistance to complete the RLC circuit. The reflected power is measured by mixing the reflected signal with the original drive signal. By changing the sample-tip distance, the impedance changes, this leads to a change in reflected power and the recorded signal. Ultimately, this high frequency method has the potential to be used in the detection and sequencing of DNA.
