Eu3+ functionalized Sc-MOFs: Turn-on fluorescent switch for ppb-level biomarker of plastic pollutant polystyrene in serum and urine and on-site detection by smartphone

The harm of plastic pollutants for human and environment is being paid more and more attention. This work first provides a fast, accurate and sensitive method for independent monitoring PS biomarker PGA in serum and urine, and the paper-based probe exhibit a new idea for design portable and easy to operate sensing devices combine with smartphone.181
