Determination of prolactin hormone in serum and urine using an electrochemical immunosensor based on poly(pyrrolepropionic acid)/carbon nanotubes hybrid modified electrodes

- The development of a voltammetric immunosensor for the determination of prolactin is reported.
- It involves covalent binding of prolactin onto poly(pyrrole propionic acid)/MWCNTs hybrids.
- A 10−2-104 ng/mL range of quantifiable antigen concentration and a LOD of 3 pg/mL were achieved.
- The immunosensor was validated by application to human serum and urine samples.
