Stephen Arnold

Stephen Arnold, University Professor of Applied Physics and member of the Othmer- Jacobs Department of Chemical and Biomolecular Engineering, used a nano-enhanced version of his team’s patented microcavity biosensor to detect a single cancer marker protein, one-sixth the size of the smallest virus, 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.
