Validation of a Novel Strategy for Fluorescence Quenching for a Self-Quenching Fluorogenic Probe and Its Application for Visual Loop-Mediated Isothermal Amplification Detection During Food Safety Analysis

Foods
The self-quenching fluorogenic probe facilitates precise identification of LAMP (loop-mediated isothermal amplification) amplicons, unaffected by non-specific products resulting from primer dimers.

Direct evidence of a blocking heavy atom effect on the water-assisted fluorescence enhancement detection of Hg²⁺ based on a ratiometric chemosensor [PDF]

, 2014
At the current stage of chemosensor chemistry, the critical question now is whether the heavy atom effect caused by HTM ions can be blocked or avoided. In the present work, we provide unequivocal evidence to confirm that the heavy atom effect of Hg²⁺ is ...
