Amino-substituted maleimides form a new class of highly emissive compounds, with large Stokes shifts (>100 nm) and high quantum yields (up to ∼60%). Emission is responsive to the maleimide's environment with both a red-shift, and quenching, observed in protic polar solvents. Aminomaleimides are easily functionalised, providing a versatile fluorescent probe.

in this research, gold nanoparticles were synthesized and functionalized by the antibody of aflatoxins. the quenching of the fluorescence of excitation emission matrices (eem) of two type of aflatoxins (b1, g1), provoked by the gold nanoparticles, was studied by principal component analysis (pca) and multivariate curve resolution with alternating least squares (mcr-als). these aflatoxins show q...

In this paper we find a possible continuation for quenching solutions to a system of heat equations coupled at the boundary condition. This system exhibits simultaneous and non-simultaneous quenching. For non-simultaneous quenching our continuation is a solution of a parabolic problem with Neumann boundary conditions. We also give some results for simultaneous quenching and present some numeric...

Depth-dependent fluorescence quenching in membranes is playing an increasingly important role in the determination of the low resolution structure of membrane proteins. This paper presents a graphical way of visualizing membrane quenching caused by lipid-attached bromines or spin labels with the help of a depth-dependent fluorescence quenching profile. Two methods are presently available to ext...

Quenching properties of gas mixture in a resistive plate chamber operated with streamer mode were investigated using optical image taken by the CCD camera and signal pulse waveform recorded by the digital oscilloscope. We have tested four quenching gases: C2H2F4, C2F6, CBrF3 and SF6. Streamer size, brightness and induced charge linearly depend on the ratio of Ar to quenching gas and their slope...

Recently almost all of the analytical methods have been used for analyzing and detecting of explosives, because of their importance in demining and unexploded ordnances operations. Fluorescence technique is one of the analytical methods. The unique features of this method caused to lots of researches in the mentioned applications. In present study, the fluorophores such as pyrene, phenol red, m...
