Microscopy. I. A review.

چکیده
structural and optical inhomogeneities which are accompanied by alterations in the optical path length (product of thickness and refractive index) or by differences in the absorption and the scatter of photons, electrons, and x-rays. The require ments for good imagery include the presence of contrast and the resolution of fine detail in cellular formed elements which have several orders of dimensional magnitude that are very approxi mately given by: [email protected] for nuclei; 1@sfor nucleoli, chromosomes, and mitochondria; and 0.1k for mi crosomes. It will be shown subsequently that for certain types of quantitative work a departure is made from conventional methodology by the preparation and the analysis of optically homo geneous cellular material. An excellent general re view on recent progress in practical microscopy is that of Barer (8).

Atomic Force Microscopy Application in Biological Research: A Review Study
Atomic force microscopy (AFM) is a three-dimensional topographic technique with a high atomic resolution to measure surface roughness. AFM is a kind of scanning probe microscope, and its near-field technique is based on the interaction between a sharp tip and the atoms of the sample surface. There are several methods and many ways to modify the tip of the AFM to investigate surface properties, ...
متن کاملBeating the Abbe diffraction limit in confocal microscopy via nonclassical photon statistics.
We experimentally demonstrate quantum enhanced resolution in confocal fluorescence microscopy exploiting the nonclassical photon statistics of single nitrogen-vacancy color centers in diamond. By developing a general model of superresolution based on the direct sampling of the kth-order autocorrelation function of the photoluminescence signal, we show the possibility to resolve, in principle, a...
