Application of electrochemical biosensors in colorectal cancer research

Malignant tumors are one of the diseases that seriously threaten human health, among which colorectal cancer is one of the common malignant tumors with high morbidity and high mortality. Early diagnosis and treatment is the main way to reduce the mortality of colorectal cancer, so the accurate detection of colorectal cancer-related substances has important clinical significance in recent years. With the rapid development of electrochemical biosensors and nanomaterials, electrochemical sensors based on nanomaterials can realize the detection of tumor-related indicators, which has the advantages of high sensitivity and strong specificity.
