Porous silicon (PSi) is a promising nanostructured material for label-free interferometric biosensing, though it currently suffers of restricted “real” applications in medical diagnostics. This is usually ascribed to PSi interferometer limited sensitivity due to mass-limited diffusion of (bio)molecules inside its nanopores. Here we report on a high-sensitivity label-free interferometric technique (i.e. Interferogram Average over Wavelength, IAW, reflectance spectroscopy) for, though not limited… CONTINUE READING
