1. A method for detecting and measuring cancer DNA, the method comprising:
exposing endogenous cancer DNA from a biological sample to a working electrode that comprises an electro-conductive material;
applying a potential to the working electrode; and
detecting an electrical signal from the working electrode that is indicative of adsorption of the endogenous cancer DNA to the electro-conductive material, wherein the electrical signal from the working electrode is different than another electrical signal generated from the working electrode when exposed to (1) one corresponding non-cancer DNA or (2) a total amount of endogenous cancer DNA from another biological sample that is different than a total amount of the endogenous cancer DNA from the biological sample.
