Abstract
The current invention provides methods for detecting trace analytes in solution or suspension using coupled micro-ring resonators. The methods of the current invention determine the presence and concentration of the target analytes in real time by exposing the micro-ring resonator to the analyte and determining the resulting rate of change of resonance wavelength experienced by a sensing micro-ring resonator as compared to a reference micro-ring resonator.
