More recently, they utilized filamentous phages to form virus-PEDOT (poly(3,4-ethylenedioxythiophene)) biocomposite nanowires and films for the electrochemical detection of cognate antibodies or prostate-specific membrane antigen (PSMA), a prostate cancer biomarker [49,81–83] (Figure 7). Here, FOLH1 is linked to Familial prostate cancer.
