As an important neurotransmitter, the concentration of dopamine (DA) reflects certain physiological conditions and DA-related diseases. Rapid monitoring DA levels is great significance in regulating body health. However, regular electrochemical sensors suffer from poor sensitivity, low selectivity interference immunity, as well a complex preparation process. Herein, we developed accessible cost-effective sensor with copper indium selenide (CuInSe2 or CIS)-modified screen-printed carbon electrode for discrimination. This was using facile one-step hydrothermal method without high-temperature quenching. Benefitting inherent merits CIS conversion Cu2+ Cu+ during catalytic reaction, attained both excellent sensitivity (2.511 μA·µM−1·cm−1) among multiple substances interfering DA. work demonstrates potential to improve analytical performance traditional sensors.
