Ultramicrotomy is a method for cutting specimens into extremely thin slices, called ultra-thin sections, that can be studied and documented at different magnifications in a transmission electron microscope (TEM). It is used mostly for biological specimens, but sections of plastics and soft metals can also be prepared.

2019年9月17日 · Ultramicrotomy is mainly used as a sample preparation method for transmission electron microscopy (TEM). It permits the internal fine structures of samples to be visualized and analyzed at nanometer scale resolution. It produces ultrathin sections of samples in …

The scope of Ultramicroscopy is to describe advances in instrumentation, methods and theory related to all modes of microscopical imaging, diffraction and spectroscopy in the life and physical sciences.

2024年11月1日 · Ultramicrotomy is the process by which a sample is cut into very thin slices or “sections”, usually for imaging by transmission electron microscopy (TEM) or relatively new techniques using scanning electron microscopy (See Array tomography in three-dimensional scanning electron microscopy for biology).

The main purpose of this article is to give a review of the most important apparatus necessary for the performance of ultramicro chemical analysis. It is obvious that the development of ultramicro methods depends almost entirely on the development of an apparatus that can handle minute quantities of samples, solutions, etc.

Do you need to produce thin or ultra-thin sections for EM sample preparation? Introducing UC Enuity, the next generation ultramicrotome that saves you valuable time and resources through its automated setup functions, providing state-of-the-art sectioning quality.

The meaning of ULTRAMICRO is being or dealing with something smaller than micro.

In this study, we have characterized sputtered iridium oxide (SIROF) electrodes in an inorganic model of interstitial fluid (model-ISF) using electrochemical impedance spectroscopy (EIS), cyclic voltammetry (CV), and voltage transient measurements during current pulsing.

Light sheet fluorescence microscopy with the UltraMicroscope II enables you to visualize whole biological systems. Moving the sample through the light sheets allows the generation of sharp and bright 3D images.

In the latest decennium, methods in clinical chemistry have improved a great deal with regard to the following aspects: accuracy; specificity; sample size; speed; number of determinations per man-hour; and costs per determination. The introduction of ultramicro methods offers advantages on most of these aspects.
