摘要

A total PSA (tPSA) assay using magnetic beads (1 mm) and a re-usable 8-channel screen printed electrochemical array is here reported. The reaction scheme is based on a one step sandwich assay. The linear range obtained is comprised between 5 and 100 ng/mL of tPSA and have a limit of detection of 1.86 ng/mL. This methodology was validated, performing determination of tPSA in serum and the results were compared with a commercial ELISA kit.
