摘要：
A method and an apparatus for determining a presence or an amount of a polyamine or its derivative in a sample, the method including: applying the sample on an electrochemical detector having a substance selection structure, wherein the substance selection structure is sensitive to the polyamine or its derivative; applying at least one voltage bias to the electrochemical detector; and detecting a change of electrical characteristics of the electrochemical detector so as to determine the presence or the amount of the polyamine or its derivative in the sample.
