  • We describe a spectroscopic comparative analysis based on the optoacoustic technique over the wavelength range from 410nm to 1000nm using a Q-switched Nd:YAG pumped optical parametric oscillator tunable
    source on a gold nanostructure solution located within a highly
    scattering medium. The advantages of this method over standard
    spectroscopy techniques are the possibility to localize and monitor the
    spectroscopic response of absorbing materials located within turbid
    media. The operation is confirmed using a comparative analysis with the
    spectroscopic results obtained from a reference measurement scheme,
    based on a highly sensitive collimated optical transmission setup in
    parallel and under the same experimental conditions as the optoacoustic
