Self-quenching dye
WebDue to the fluorescent quenching mechanism of GO on the dye-labeled probes, the initial micromotors with dye-labeled probes exhibited little fluorescence, as shown in Fig. Fig.4A. 4 A. Once they were exposed to the solution containing targets, the dye-labeled probes preferentially bounded with the target sequences, leaving away from the GO ... WebFluorophore self-quenching occurs even in simple Walter proposed that “aggregation” was the cause of dye solutions and has been known since 1888, when quenching, and that fluorescence arose only from single molecules (monomers) [3]. However, the mechanisms of self-quenching are still not entirely understood. It appears

Quenching refers to any process which decreases the fluorescence intensity of a given substance. A variety of processes can result in quenching, such as excited state reactions, energy transfer, complex-formation and collisional quenching. As a consequence, quenching is often heavily dependent on pressure and temperature. Molecular oxygen, iodide ions and acrylamide are common chemic…
