Singlet Oxygen Mediated & Amplified Biosensing with Conjugated Polymers

Sarrafpour, Syena

2012

Description
  • This project combines both a chemical amplification as well as an optical amplification through the binding of singlet oxygen (1O2). When the photosensitizer, eosin 5-isothiocyanate, is bound to NeutrAvidin labeled biotinylated microspheres, 1O2 is generated; the singlet oxygen then reacts with the quenching conjugated acenes on the thin film to restore the conjugated polymer's fluorescence.
