Fluorescence is a well-known phenomenon with ... One important phenomenon that occurs to excited molecules is called quenching. This is usually a chemical reaction that impedes the molecules ...

[45] First, the multicolor dye-labeled aptamers hybridize with DNA strands on the AuNPs, resulting in fluorescence quenching of the dyes. Then, in the presence of different target molecules ...

Light emission from molecules, particularly fluorescence, has fascinated scientists ... phenomenon that challenges the conventional quenching behavior seen in many materials.

A higher quenching efficiency lowers background fluorescence and enhances assay sensitivity.
