Construction of an Electrochemiluminescence Immunosensor Based on a Pre-Concentration Enhanced Mechanism for Ultrasensitive Detection of CEA

Key Points

• The study aims to create an immunosensor that allows for ultrasensitive detection of carcinoembryonic antigen (CEA).
• Developed an electrochemiluminescence (ECL) immunosensor with a pre-concentration enhancement mechanism.
• Conducted tests to optimize conditions for CEA detection.
• Utilized a quantitative approach to assess sensitivity and specificity.
• Achieved significantly increased sensitivity for CEA detection compared to traditional methods.
• Demonstrated reliable quantification of CEA in samples, indicating improved early diagnosis potential.
