Electrochemical Investigation of Testosterone Using a AuNPs Modified Electrode

Polycystic ovarian syndrome (PCOS) is a disease that occurs extensively among females during their reproductive period and that can be diagnosed using the testosterone level in the body. In the present report, a biosynthesized gold nanoparticle (AuNP)-based electrochemical impedance immunosensor was fabricated for the first time and used for the detection of testosterone with a wide detection range of 10 ng/mL - 0.5 μg/mL. In addition, our proposed immunosensor showed excellent performance in the detection of testosterone in saliva specimens.
