The Most Sensitive Cancer Blood Test Yet
A CRISPR-powered light sensor detected trace amounts of cancer biomarkers in the blood
-
1
Scientists developed an ultra-sensitive blood test that detects cancer-related microRNAs at sub-attomolar levels.
-
2
The test identifies specific microRNAs linked to early tumor development, providing potential early warning signs of cancer.
-
3
The optical sensing system uses second-harmonic generation and a layered structure with MoS₂ and quantum dots for detection.
-
4
The method demonstrated stronger signal differences in lung cancer patients compared to standard RT-qPCR testing.
-
5
This technology could enable early blood screenings for lung cancer and facilitate personalized treatment monitoring.
