Photostability of oxygen-sensitive core-shell nanofibers

Recent work from the Lannutti group at the Ohio State University was published in Journal of Sensors and Actuators B: Chemical, evaluating compositional parameters and other factors governing fiber design appropriate to long-term sensor applications. These nanofibers contain an oxygen-sensitive palladium (II) porphyrin species within a polysulfone core; an outer polycaprolactone shell protects the core from the surrounding environment. This study provides a detailed investigation of photobleaching processes for a time scale (1,000 hr) orders of magnitude longer than is typically investigated. It was shown that some oxygen-sensitive signal is still present even after 1,000 hr of continuous photobleaching.
