Lateral flow immunoassay based on dual spectral-overlapped fluorescence quenching of polydopamine nanospheres for sensitive detection of sulfamethazine.

Journal of Hazardous Materials, 2021
Herein, we propose a lateral flow immunoassay (LFIA) based on the dual spectral-overlapped fluorescence quenching of polydopamine nanospheres (PDANs) caused by the inner filter effect to sensitively detect sulfamethazine (SMZ). The fluorescence quenching

Interaction of graphene oxide with bovine serum albumin: A fluorescence quenching study.

Spectrochimica Acta Part A - Molecular and Biomolecular Spectroscopy, 2019
Fluorescence quenching was used to elucidate the binding interaction mechanism between bovine serum albumin (BSA) and graphene oxide (GO). By analyzing the values of Stern-Volmer quenching constant (KSV) and binding constant (KA) which were affected by ...

Fluorescence quenching of tryptophan by trifluoroacetamide

Biochimica et Biophysica Acta (BBA) - General Subjects, 1984
Trifluoroacetamide was found to be a good quencher of tryptophan fluorescence, and the quenching was shown to proceed via both a dynamic and a static process. The respective quenching constants were determined by the measurement of the decrease of the fluorescence lifetime in the presence of the quencher.

Increasing Photothermal Efficacy by Simultaneous Intra‐ and Intermolecular Fluorescence Quenching

Advanced Functional Materials, 2019
Recently, using in situ self‐assembly‐induced fluorescence quenching (i.e., intermolecular quenching denoted herein) of a photothermal agent (PTA) to enhance its photothermal efficiency has proven to be a successful photothermal therapy (PTT) strategy ...

Detection of oxygen by fluorescence quenching

Applied Optics, 1985
The incorporation of an aromatic hydrocarbon fluorescent compound into silicone allows utilization of fluorescence quenching as a mechanism to measure molecular oxygen concentration in the composite matrix. Excitation and emission spectra of the aromatics change in agreement with the Franck-Condon model when the universal solvent is benzene ...

Fluorescence quenching of acridines by strandin

Archives of Biochemistry and Biophysics, 1961
Abstract The interaction of four acridine compounds with strandin has been studied, with special attention being directed to acriflavine. In all cases fluorescence quenching by strandin occurs, the nature of the quenching curve depending on the dye involved.
