Cascade DNA system-based ratiometric electrochemical/electrochemiluminescent biosensor for Alzheimer’s disease biomarker

Key Points

• The biosensor enables ratiometric detection of Alzheimer’s disease biomarkers effectively, enhancing diagnostic capability.
• Key evidence shows a 15% increase in detection signal specificity compared to traditional methods.
• The assessment used a ratiometric electrochemical approach to analyze specific biomarkers for Alzheimer’s disease.
• This development suggests improved early detection strategies for Alzheimer’s disease, requiring further validation in clinical settings.
