Résumé :
Methods for the analysis of biomolecular markers of health and disease are in high demand. There is ongoing need for measurements that are not only more sensitive, more selective, faster, and richer in information, but also more accessible. Technologies continue to advance, but often with cost and complexity that makes them available to fewer and fewer people. In response, we have designed fluorescent materials that enable molecular assays and cellular analyses on simply engineered smartphone-based devices amenable to low-resource, point-of-care settings. This presentation will give an overview of some of our recent research in this area, including how materials like semiconductor quantum dots (QDs), semiconducting polymer dots (Pdots), supra- and super-nanoparticle assemblies of nanoparticles, and luminescent lanthanide complexes benefit this endeavor. Our unique approaches to the preparation of these materials, their (macro)molecular functionalization, bioconjugation, and characterization will be described alongside examples of applications, such as enhanced sensing of enzyme activity, smartphone-based time-gated FRET assays, and smartphone-based flow cytometry.
