Scientists have developed a light-based sensor that can identify tiny amounts of cancer biomarkers in blood samples, potentially enabling earlier detection than traditional scans. The technology combines DNA nanostructures, CRISPR, and quantum dots to produce a clear signal from just a few molecules. Tests on lung cancer patient serum showed promising results at sub-attomolar levels.
The FDA granted several breakthrough device designations in September 2025 for innovative medical technologies. These designations expedite the development and review of devices addressing unmet needs. Updates include new approvals and predetermined change control plans.
