## Abstract Impedance biosensors are a class of electrical biosensors that show promise for pointβofβcare and other applications due to low cost, ease of miniaturization, and labelβfree operation. Unlabeled DNA and protein targets can be detected by monitoring changes in surface impedance when a ta
