This new blood test could detect cancer before it shows up on scans
Researchers report a light-based sensor that combines DNA nanotechnology, CRISPR, and quantum dots to achieve sub-attomolar detection of cancer biomarkers, demonstrating signals in lung cancer patient serum and suggesting potential for portable early-detection blood tests.
Why it mattersCRISPR-enabled quantum-dot sensor detecting sub-attomolar biomarkers suggests investors should prioritize clinical validation for early screening.
