Abstract: The invention relates to a spectrophotometer, especially a spectrophotometer that can carry out simultaneous analysis at different points on the same sample (4), with a high spatial resolution and without requiring a mechanical system for physical scanning along the sample. This is obtained by the provision of means for processing the light received by the photodetectors (5), said processing means having a correlation wherein each of the photodetectors (5) corresponds to a spatial point on the sample (4).In the case of dark field applications, the present invention ensures the standardization of the data using the same measure.

Abstract: The invention relates to a method and a system of mechanical resonance transduction for analyte analysis, suitable for its use in the identification of nanoparticles in the range between 1 MHz and 300 GHz, said method being characterized in that it comprises the following steps: a) disposing at least one analyte, possessing at least one mechanical vibration mode, on at least one mechanical resonator sensor that possesses at least one mechanical vibration mode, selectable in a plurality of working frequencies; b) monitoring the mechanical spectra of the of the analyte and the resonator sensor; c) varying the at least one mechanical vibration mode until at least one mechanical vibration mode reaches a strong coupling situation with the at least one mechanical vibration mode; d) collecting the frequency data at which the strong coupling occurs; e) estimating the resonance frequency and quality factor of the at least one mechanical vibration mode from the strong coupling frequency data obtained in step d).
