Electrochemical Biosensors Based on Carbon Nanotubes (CNTs) Used to Diagnosis Pancreatic and Liver Cancer

Abstract

This review examines recent advancements in carbon nanotube (CNT)-based electrochemical biosensors for the diagnosis of pancreatic and liver cancer biomarkers. The unique structural and functional properties of CNTs, such as their high surface area, excellent electrical conductivity, and biocompatibility, make them highly effective for sensitive and specific detection of cancer-associated biomarkers. The review summarizes key studies that have demonstrated the potential of CNT-based biosensors in early cancer biomarker identification. Various sensor designs, fabrication techniques, and detection mechanisms are discussed to highlight the progress made in this field. Additionally, the advantages and limitations of CNT-based biosensors compared to conventional diagnostic methods are analyzed. By providing a comprehensive overview of the latest research, this study underscores the role of CNTs in enhancing the accuracy and efficiency of cancer biomarker detection. Future perspectives on improving CNT-based biosensor technology, including strategies for increasing selectivity, stability, and integration with point-of-care diagnostic systems, are also explored. Also, this review focuses on the applications of CNT-based biosensors in the identification of pancreatic and liver cancer biomarkers and discusses current research progress.
