Abstract
AbstractAlkaline phosphatase (ALP) is an important marker for many diseases, yet an efficient and reliable detection method is still lacking. Here, we present a novel photonic alginate hydrogel particle as an ALP sensor based on the competitive combination of an intermediary agent, the pyrophosphate ion (PPi), with a hydrogel crosslinker, which can trigger a phase-transition response from the hydrogel. This response can be converted into dual optical readouts, a fluorescence signal and a structural color signal. Quantitative determination of ALP was established based on this dual-indicator system with high accuracy and reliability. These features suggest potential ideal applications of responsive photonic hydrogel particles to detect ALP and other macromolecules.
