Abstract
In one aspect, methods of sensing are described herein. In some embodiments, such a method comprises disposing a population of luminescent species in a test sample, exposing the test sample to electromagnetic radiation having a wavelength corresponding to an excitation wavelength of the luminescent species, detecting light emitted by the luminescent species within a detection region of the test sample, and correlating the light emitted by the luminescent species within the detection region to a presence or absence of an analyte within the test sample. The luminescent species, in a non-aggregated state, exhibits luminescence blinking and, in an aggregated state, does not exhibit luminescence blinking. Additionally, correlating the light emitted by the luminescent species to the presence or absence of the analyte comprises determining whether the light emitted by the luminescent species within the detection region is blinking luminescence or non-blinking luminescence.
