Breaking the Diffraction Barrier Using Fluorescence Emission Difference Microscopy
We propose a novel physical mechanism for breaking the diffraction barrier in the far field. Termed fluorescence emission difference microscopy (FED), our approach is based on the intensity difference between two differently acquired images. When fluorescence saturation is applied, the resolving ability of FED can be further enhanced. A detailed theoretical analysis and a series of simulation t...
متن کاملFluorescence microscopy with diffraction resolution barrier broken by stimulated emission.
The diffraction barrier responsible for a finite focal spot size and limited resolution in far-field fluorescence microscopy has been fundamentally broken. This is accomplished by quenching excited organic molecules at the rim of the focal spot through stimulated emission. Along the optic axis, the spot size was reduced by up to 6 times beyond the diffraction barrier. The simultaneous 2-fold im...
متن کاملFluorescence and fluorescence microscopy
The concept of specific cellular antigen staining by use of an immunofluorescent technique was introduced by AH COONS and co-workers about 60 years ago. Fluorescent probes are efficient tools and enable the detection of particular components in complex structures of organs including live cells. Under the condition of specific molecular interactions, fluorochrome labeled ligands allow the select...
متن کاملFluorescence Microscopy
When organic or inorganic specimens absorb and subsequently reradiate light, the process is typically a result of fluorescence or phosphorescence. Fluorescence emission is nearly simultaneous with the absorption of the excitation light as the time delay between photon absorption and emission is typically less than a microsecond. When the emission persists long after the excitation light is exti...
متن کاملFrontiers in fluorescence microscopy.
How we see organisms and cells depends on the tools at our disposal. For over 150 years, biologists were forced to rely on fixed, dehydrated and stained specimens in order to guess how the living cells could function. It all changed abruptly during the last two decades when the rapid development of novel imaging techniques revolutionized the way scientists look at the structures of life alive.
