ITO-PET electrochemical biosensor functionalized with carboxylated graphene oxide for prostate cancer biomarker detection
. It demonstrated high selectivity and recovery value from 85.4% - 128.7%, with a relative standard deviation (RSD) below 15.5% in spiked serum samples. Overall, the developed GO-COOH@ITO-PET immunosensor successfully spans the clinically relevant cut-off levels, and offers strong potential as a low-cost, rapid, and quantitative platform for PSA screening in point-of-care settings.
