Summary: Cancer is a malignant disease with a high fatality rate, and early screening with rapid and accurate detection is crucial for improving the survival rate. Electrochemical biosensors that detect cancer biomarkers in blood offer advantages such as low invasiveness, fast diagnosis, and low cost. However, there is a trade-off between sensitivity and selectivity, which limits the detection of trace amounts of biomarkers. Recently, nanomaterials with improved sensitivity and selectivity have been developed to address this issue. This review introduces different categories of state-of-the-art electrochemical biosensors, discusses their operating principles and advantages/disadvantages, and evaluates the existing detection strategies and performance of nanomaterial-based cancer biosensors.
