Fluorescence Chemosensing of Mg2+ by Phenylhydrazone of a Difluorenylpiperidin-4-one
Magnesium is an abundant element in the environment. Magnesium ion sensing by fluorescence spectral method is of importance due to the need for the detection of the metal in the human body and the environment. In this paper, we report the Mg2+ ion sensing behavior of the phenylhydrazone derivative of a difluorenylpiperidin-4-one. The preparation method of this compound is simple. The compound s...
متن کاملWavelength-dependent metal-enhanced fluorescence using synchronous spectral analysis
The fluorescence spectrum of Au-clusters (8and 25-atom), which covers the spectral range 350–900 nm, is dramatically enhanced in the presence of plasmon supporting plate-well deposited nanoparticles. The wavelength-dependent metal-enhanced fluorescence (MEF spectrum) correlates well with the plasmon specific scattering spectrum, i.e. the synchronous scatter spectrum of the silver surface of pla...
متن کاملIndium nanodeposits: A substrate for metal-enhanced fluorescence in the ultraviolet spectral region
We have studied a metallic substrate, composed of indium nanodeposits, for metal-enhanced fluorescence MEF in the ultraviolet UV spectral region. Indium coated slides were prepared using the thermal vapor deposition technique. Theoretical finite difference time domain simulations and experimental studies show that plasmon enhanced absorption and coupled radiation through the scattering componen...
متن کاملMetal-Enhanced Fluorescence from Nanoparticulate Zinc Films.
A detailed study of metal-enhanced fluorescence (MEF) from fluorophores in the blue-to- red spectral region placed in close proximity to thermally evaporated zinc nanostructured films is reported. The zinc nanostructured films were deposited onto glass microscope slides as individual particles and were 1-10 nm in height and 20-100 nm in width, as characterized by Atomic Force Microscopy. The su...
متن کاملMetal-enhanced fluorescence: an emerging tool in biotechnology.
Over the past 15 years, fluorescence has become the dominant detection/sensing technology in medical diagnostics and biotechnology. Although fluorescence is a highly sensitive technique, where single molecules can readily be detected, there is still a drive for reduced detection limits. The detection of a fluorophore is usually limited by its quantum yield, autofluorescence of the samples and/o...
