Submicrometer spatial resolution of metal-enhanced fluorescence.
Enhanced fluorescence emission intensity from fluorescein was observed on glass slides covered with thin films of silver nanoparticles using a confocal laser-scanning microscope. The silver nanoparticle film increased the emission intensity of fluorescein by an average of at least three-fold in the area studied. Statistics are given on the enhancement of individual areas of the silver particle ...
متن کاملMetal-enhanced fluorescence.
Fluorescence spectroscopy is entrenched throughout the life sciences today and is used for a variety of applications, including the detection of chemical or biological analytes/species, in reporting molecular events or for the understanding of microenvironments, such as local viscosity, polarity and voltage measurements, to name but just a few. In the majority of these fluorescencebased measure...
متن کاملHard X-Ray Microscope With Submicrometer Spatial Resolution
A high-resolution hard x-ray microscope is described. This system is capable of detecting line features as small as 0.6 µm in width, and resolving line pairs 1.2-µm wide and 1.2-µm apart. Three types of two-dimensional image detectors are discussed and compared for use with hard x rays in high resolution. Principles of x-ray image magnification are discussed based on x-ray optics and diffractio...
متن کاملMetal-enhanced e-type fluorescence.
In this letter, we report metal-enhanced e-type fluorescence. Eosin in close proximity to silver island films (SiFs) shows enhanced e-type fluorescence with an approximately two-fold higher intensity observed from SiFs, as compared to a control sample. Our findings suggest two complementary mechanisms for the enhancement: surface plasmons can radiate e-type delayed fluorescence efficiently and ...
متن کاملMetal-enhanced fluorescence exciplex emission.
In this letter, we report the first observation of metal-enhanced exciplex fluorescence, observed from anthracene in the presence of diethylaniline. Anthracene in the presence of diethylaniline in close proximity to Silver Island Films (SIFs) shows enhanced monomer and exciplex emission as compared to a non-silvered control sample containing no silver nanoparticles. Our findings suggest two com...
