Abstract

Toward a Smart Optical Biosensor Based on Nanoporous Anodic Alumina (NAA): By modifying the pore geometry in nanoporous anodic alumina we are able to change the effective medium at will and tune the photoluminescence of NAA. The oscillations in the PL spectrum are converted into exclusive barcodes, which are useful for developing optical biomedical sensors in the UV-Visible region.
