Abstract
Embodiments of the present invention relate to a system and method for practicing spectrophotometry using light emitting nanostructures. Specifically, embodiments of the present invention include a physiologic sensor comprising a sensor body configured for placement adjacent pulsatile tissue of a patient, a first light emitting nanostructure device configured to emit light at a first wavelength through the pulsatile tissue, a second light emitting nanostructure device configured to emit light at a second wavelength through the pulsatile tissue, and a light detector configured to detect the light at the first wavelength and the light at the second wavelength after dispersion through the pulsatile tissue.
