Abstract
- We describe a novel ‘switch-off’ biosensing strategy for the detection of chymotrypsin based on surface plasmon resonance (SPR) and surface-enhanced Raman scattering (SERS) spectroscopy. This approach analyzes the fingerprint spectrum of the chymotrypsin-catalyzed substrate. The lowest probed concentration is 0.4 nM for chymotrypsin. [ABSTRACT FROM AUTHOR]
