Description

Developing methods for the detection of single molecule interacting with the environment has been a large area of research. These methods are quite varied in their execution and include antigen binding, surface plasmon resonance, fluorescence among many others. These methods all take advantage of the fact that molecular processes often change how a substrate interacts with light when a certain molecule is bound to it. With this in mind, we investigate if energy level changes of a fluorescent molecule due to ambient interactions can be detected by monitoring the two-time intensity-intensity correlation spectrum of the molecule when driven by electromagnetic waves. As these correlations depend on the magnitude of detuning in the driving excitation, if the two-time intensity-intensity correlation spectrum were to be continuously monitored for a target transition in a three-level system, any changes that occur in the correlation spectrum could used to determine if the energy levels have changed and if any interactions have taken place.
