Abstract
We demonstrate simultaneous detection of two nanoparticle species using phase-sensitive optical coherence tomography with photothermal excitation at two wavelengths matched to the distinct absorption peaks of the nanoparticles. To minimize bulk heating of the sample, a novel single-pulse excitation scheme is proposed and its sensitivity is characterized.
