1. Photothermal detection of gold nanoparticles using phase-sensitive optical coherence tomography

    Photothermal detection of gold nanoparticles using phase-sensitive optical coherence tomography
    The detection of a gold nanoparticle contrast agent is demonstrated using a photothermal modulation technique and phase sensitive optical coherence tomography (OCT). A focused beam from a laser diode at 808 nm is modulated at frequencies of 500 Hz – 60 kHz while irradiating a solution ... [Opt. Express 16, 4376-4393 (2008)]
