Electrochemical Sensor Based on Nanomaterials and Its Application in the Detection of Alpha Fetoprotein
Abstract
Hepatocellular carcinoma development and many other tumors are closely related to alpha-fetoprotein (AFP), its determination can be used as a positive test for tumors. It is mainly used clinically as a serum marker to diagnose and monitor the efficacy of primary hepatocellular carcinoma. Therefore, a variety of biosensors have been developed to detect AFP. Electrochemical sensors integrate a variety of detection methods. They have inherent advantages over other types of sensors, they are fast, portable, simple, and highly sensitive. Some meaningful electrochemical biosensors work with nanomaterials acting as signal amplification elements or as signal amplification catalysts. This review introduced the field of biosensors and discuss about the use of nanomaterials in electrochemical sensing, specificity electrochemical biosensing of AFP. The study ends with a discussion about the prospects for nanomaterial-based signal amplification and future research directions.
