Interaction of adrenocorticotropin peptides with microheterogeneous systems - A fluorescence study
(ELSEVIER SCIENCE BV, 2009)
Adrenocorticotropin (ACM) and alpha-melanocyte stimulating hormone (alpha-MSH) are peptides which present many physiological effects related to pigmentation, motor and sexual behavior, learning and memory, analgesia, ...
Multivariate curve resolution strategy for non-quadrilinear type 4 third-order/four way liquid chromatography–excitation-emission fluorescence matrix data
(Elsevier Science, 2018-11)
For the first time, a third-order/four-way system having instrumental modes depending on each other was experimentally generated and it was successfully resolved. Non-quadrilinear type 4 data, constituted by liquid ...
Nanometer resolution imaging and tracking of fluorescent molecules with minimal photon fluxes
(American Association for the Advancement of Science, 2017-02)
We introduce MINFLUX, a concept for localizing photon emitters in space. By probing the emitter with a local intensity minimum of excitation light, MINFLUX minimizes the fluorescence photons needed for high localization ...
Entropy-driven binding of octyl gallate in albumin: Failure in the application of temperature effect to distinguish dynamic and static fluorescence quenching
(2020-07-01)
Fluorescence quenching is widely used to obtain association constants between proteins and ligands. This methodology is based on assumption that ground-state complex between protein and ligand is responsible for quenching. ...

End-to-end distance distribution in bradykinin observed by Forster resonance energy transfer
(Elsevier B.V., 2000-04-06)
Forster resonance energy transfer (FRET) was used to study the conformational dynamics of bradykinin related peptides. the fluorescent probe aminobenzoic acid (Abz) bound to the amino terminal of bradykinin maintained its ...
Interaction between nitroxyl radicals and CdTe quantum dots: Determination of fluorescence-quenching mechanisms in aqueous solution
(2019)
The present work characterizes the optical properties of CdTe quantum dots (CdTe QDs) after interaction with nitroxyl radicals based on steady-state and time-resolved fluorescence spectroscopy studies. QDs of different ...
