Nano scientists reach holy grail in label-free cancer marker detection: Single molecules

Scientists have announced a nano-enhanced version of a biosensor has detected a single cancer marker protein and even smaller molecules below the mass of all known markers. This achievement sets a new benchmark for the most sensitive limit of detection, and may significantly advance early disease diagnostics.
