By combining electrochemical detection technique and electronic technique, a portable device which adopted differential pulse voltammetry (DPV) measurement was developed to meet the needs of high sensitivity and on-site rapid detection for tumor marker. The voltage and current resolution of portable device were 0.8 mV and 1 nA, respectively. Combined with laboratory made paper-based analytical device, carcinoembryonic antigen(CEA) was tested by portable device. Experimental results revealed that the DPV peak currents showed good linear relation with the logarithm of CEA concentration in the range from 1 μg/L to 500 μg/L. Its corresponding correlation coefficient was 0.998 and the limit of detection was 10 pg/mL. According to the principle of specific binding of antibody and antigen and electrochemical detection, CEA concentration could be calculated automatically according to the linear equation. The portable device had high sensitivity and low detection limit features which could be widely used in the point-of-care testing of tumor marker.
