A Simple Ratiometric Electrochemical Aptasensor Based on Exonuclease III-Assisted Target Recycling for Ultrasensitive Detection of Prostate Specific Antigen
Prostate specific antigen (PSA) is considered as an important biomarker in prostate cancer diagnosis. Herein, an ultrasensitive ratiometric electrochemical aptasensor was constructed for analyzing PSA. The ferrocene (Fc)-labeled thiolated hairpin probe 2 (Fc-HP2) was conjugated to the gold nanoparti...
