- Existing diagnostic methods often require complex equipment and trained personnel.
Purpose of the Study:
- To develop a dual-colorimetric assay for simultaneous detection of two miRNAs.
- To achieve high sensitivity and selectivity in miRNA detection.
- To enable rapid lung cancer diagnosis using clinical serum samples.
Main Methods:
- Development of a novel dual-colorimetric detection kit.
- Simultaneous measurement of two specific miRNA targets.
- Visual data interpretation without specialized equipment.
- Validation using clinical serum samples.
Main Results:
- The developed kit successfully detected two miRNAs with high sensitivity and selectivity.
- The assay provided easily readable results by the naked eye.
- The kit effectively distinguished between patients and healthy individuals.
- Accurate lung cancer diagnosis was achieved in a short timeframe.
Conclusions:
- A user-friendly and efficient dual-colorimetric assay for miRNA detection has been established.
- This method offers a promising tool for rapid and accessible lung cancer diagnosis.
- The kit's ability to distinguish patients from healthy individuals highlights its clinical potential.
