Abstract

The mechanism of fluorescence resonance energy transfer (FRET) was studied after inorganic nanomaterials have replaced organic dyes as energy donors and acceptors. Quantum dots and graphene oxide have been used for construction of FRET sensors. Next the fluorophores are incorporated to paper-based lateral flow assays toward point-of-care testing. The fluorescence sensors have sued for detection of heavy metal ions and protein biomarkers.
