Recent Advances on Biomarkers and Bioreceptor Used for Cancer Detection

In the past 50 years, cancer has become one of the major causes of death in the world. Researchers are currently implementing various strategies to identify and prevent this disease, including treatment methods, molecular imaging technology and ultrasensitive monitoring of cancer biomarkers using innovative biosensor tools. Monitoring biomarkers will prove very useful for preventive measures. What is used to identify biomarkers is called a biological receptor. This review discusses the latest developments in the field of cancer biomarkers and bioreceptors. It introduces the biomarkers widely used in recent years, including proteins, nucleic acids, circulating tumor cells, and bioreceptors used for recognition, such as antibodies and aptamer. Moreover, this review discusses the advantages and disadvantages of various biomarkers and bioreceptors.
