Light-based sensor detects early molecular signs of cancer in the blood. By combining nanostructures made of DNA with quantum dots and #CRISPR gene editing technology, the highly sensitive sensor detected lung cancer biomarkers from patient samples at sub-attomolar levels. In the future, the technology could enable simple blood screenings for lung cancer before a tumor might be visible on a CT scan.
