A novel electrochemical aptamer biosensor based on tetrahedral DNA nanostructures and catalytic hairpin assembly for CEA detection
Abstract
At present, carcinoembryonic antigen (CEA) is a commonly used biomarker to diagnose cancers. Accurate and specific detection of CEA in clinical samples is of great significance for the diagnosis, treatment and prognosis of related cancers. In this research, we developed an enzyme-free electrochemical aptamer biosensor for highly sensitive detection of CEA based on tetrahedral DNA nanostructures (TDNs) and target-assisted catalytic hairpin...
