Bio-inspired enol-degradation for multipurpose oxygen sensing†
Abstract
Inspired by the enol-degradation of luciferin, a new oxygen sensor with oppositely changed color and fluorescence has been designed. This new reaction-based dual mode sensor can not only be used as a highly selective instant “fluorescence on” oxygen probe, but also as a freshness indicator of food or food materials by using its property of time-adjustable color fading.
