Scientists have used a special type of biosensor to detect a single cancer marker protein that is one-sixth the size of the smallest virus.
The achievement shatters the previous record, setting a new benchmark for the most sensitive limit of detection, and may significantly advance early disease diagnostics.
The team at the Polytechnic Institute of New York University (NYU-Poly) set a record recently using the same technique to detect in solution the smallest known RNA virus, MS2, with a mass of 6 attograms.
