Fluorescent Polymeric Nanofibers as Ratiometric Multiplexed Skin Sensors of pH and Oxygen

open access: yesAdvanced Healthcare Materials, EarlyView.
Fluorescent polymeric nanofibers and nanorods are produced as ratiometric sensors of two important physiological parameters: pH and oxygen. They operate by dual Forster resonance energy transfer from large number of energy donor dyes to limited number of two distinct energy acceptors, enabling simultaneous sensing of pH and oxygen.
