Paper-based fluorescent sensor based on molecularly imprinted polymers and upconversion nanoparticles for selective and sensitive D-proline detection in human serum and saliva.
D-Proline has been reported as a potential biomarker for gastric (stomach) cancer, creating a demand for practical and rapid analytical approaches for early diagnosis using simple and non-invasive clinical samples. In this work, a microfluidic paper-based analytical device (µPAD) integrating molecularly imprinted polym...
