Resumen:
We investigate theoretically the limit to the resolution imposed by the fundamental optical noises in film-based chemical sensors interrogated by optical reflectometry. We suggest a dynamic reflectometry approach as a possible technique to achieve the ultimate resolution. We find that a theoretical resolution around 1010 absorbed analyte molecules/cm2 is possible in different cases. In the case of conducting films appreciably lower values may be possible.
