Schematic diagram of the nanoporous AAO reflective interferometric sensor. The basic optical setup includes an AAO platform placed into a microfluidic channel, fibre optic probe, light source, CCD detector, and computer. The principle of the interaction of light with AAO pores is presented on the left, and the generation of the interference pattern (Fabry-Perot fringes) processed by FFT analysis into a real signal is shown on the right.
