Diagnosis of cancer in the early stages can help to treat efficiently and reduce cancer-related death. Cancer biomarkers can respond to the presence of cancer in body fluids before the appearance of any other symptoms of cancer. The integration of nanomaterials into biosensors as electrochemical platforms offers rapid and sensitive detection for cancer biomarkers. The use of surface-modified electrodes by carbon nanomaterials and metal nanoparticles enhances the performance of electrochemical analysis in biosensing systems through the increase of bioreceptors loading capacity on the surface. In this review, the novel approaches based on nanomaterial-modified systems in point of care diagnostics are highlighted.
