1. A method for detecting an analyte in solid tissue in vitro comprising:

  • placing the solid tissue at a predetermined position;

    irradiating the solid tissue with a pulsed wavelength of light selected to pass through the solid tissue with insubstantial absorption and to be at least partially absorbed by the analyte;

    acoustically sensing a photoacoustic response generated by said step of irradiating for a period of time to obtain a photoacoustic waveform;

    analyzing the photoacoustic acoustic waveform and attributing a detected response peak to the presence of analyte.
