We introduce electrospun nanofibers as new materials to create optical sensor membranes. These fibers are an emerging material in biosensing and chemosensing because they have a high porosity, offer a high surface-to-volume ratio and an immense surface area, can be mass-produced and are reusable. By the choice of suitable polymers and optical indicators, porous sensor membranes are formed that provide analyte-capture and enrichment by ionic interactions and subsequent analyte detection or release.
