: The prostate-specific antigen (PSA) has been considered a crucial serological marker for distinguishing prostate based cancer. This surveys recent progress in the construction of nanomaterial-based electrochemical immunosensors for a PSA. This review (from 2015 to 2020) reports the latest progress in PSA sensing based on the employ of different types of nanostructured materials. The most popular used nanostructured materials are metal, metal oxide, carbon-based nanomaterials, and their hybrid architectures utilized for distinct amplification protocols. In this review, the electrochemical immunosensors for prostate-specific antigen sensing are classified into three categories such as sandwich type@labeled, label free@nonlabeled and aptamer-based electrochemical immunosensor.
