Practical Electron Microscopy

For this new edition, the chapters on photography and the electron microscope have been completely rewritten and two new chapters have been added--on immuno electron microscopy using colloidal gold and on useful specialized techniques.

In the spring of 1963, a well-known research institute made a market survey to assess how many scanning electron microscopes might be sold in the United States. They predicted that three to five might be sold in the first year a commercial SEM was available, and that ten instruments would saturate the marketplace. In 1964, the Cambridge Instruments Stereoscan was introduced into the United States and, in the following decade, over 1200 scanning electron microscopes were sold in the U. S. alone, representing an investment conservatively estimated at $50,000- $100,000 each. Why were the market surveyers wrongil Perhaps because they asked the wrong persons, such as electron microscopists who were using the highly developed transmission electron microscopes of the day, with resolutions from 5-10 A. These scientists could see little application for a microscope that was useful for looking at surfaces with a resolution of only (then) about 200 A. Since that time, many scientists have learned to appreciate that information content in an image may be of more importance than resolution per se. The SEM, with its large depth of field and easily that often require little or no sample prepara interpreted images of samples tion for viewing, is capable of providing significant information about rough samples at magnifications ranging from 50 X to 100,000 X. This range overlaps considerably with the light microscope at the low end, and with the electron microscope at the high end.

Electron microscopy (EM) is a technique through which high resolution images of biological and non-biological specimens are obtained. Electrons are the primary source of illuminating radiation that provide high resolution images. This technique is applied in biomedical research to examine the detailed structure of tissues, cells, organelles and macromolecular complexes. The two main types of electron microscopes include transmission electron microscope (TEM) and scanning electron microscope (SEM). The TEM is used to view thin specimens such as tissue sections and molecules through which electrons can pass, generating a projection image. Common applications of TEM include viewing the interior of cells (in thin sections), the structure of protein molecules (contrasted by metal shadowing), and the arrangement of protein molecules in cell membranes (by freeze-fracture). In SEM, the image is formed by scanning a focused electron beam onto the surface of the specimen in a raster pattern. SEMs with appropriately equipped devices can be used to study the topography and atomic composition of specimens. The book studies, analyzes and presents the recent developments related to electron microscopy and its significance in modern times. Students, researchers, and experts of electron microscopy will likely benefit from this book.

'Although the study of such defects is regularly examined at length in more general books on electron microscopy, this text in which they are centre-stage will surely be appreciated.' [Read Full Review]UltramicroscopyThis unique reference text provides those who are studying crystal lattice defects using a transmission electron microscope (TEM) with a basic knowledge of transmission electron microscopy. As it has been written for beginners, the principles of both transmission electron microscopy and crystallography have been clearly and simply explained, with the use of many figures and photographs to aid understanding. Mathematics is avoided where possible, and problems and exercises are amply provided.

Diagnostic Electron Microscopy Diagnostic Electron Microscopy: A Practical Guide to Interpretation and Technique summarises the current interpretational applications of TEM in diagnostic pathology. This concise and accessible volume provides a working guide to the main, or most useful, applications of the technique including practical topics of concern to laboratory scientists, brief guides to traditional tissue and microbiological preparation techniques, microwave processing, digital imaging and measurement uncertainty. The text features both a screening and interpretational guide for TEM diagnostic applications and current TEM diagnostic tissue preparation methods pertinent to all clinical electron microscope units worldwide. Containing high-quality representative images, this up-to-date text includes detailed information on the most important diagnostic applications of transmission electron microscopy as well as instructions for specific tissues and current basic preparative techniques. The book is relevant to trainee pathologists and practising pathologists who are expected to understand and evaluate/screen tissues by TEM. In addition, technical and scientific staff involved in tissue preparation and diagnostic tissue evaluation/screening by TEM will find this text useful.

The first edition of this book was widely praised as an excellent introduction to electron microscopy for materials scientists, physicists, earth and biological scientists. This completely revised new edition contains expanded coverage of existing topics and much new material. The author presents the subject of electron microscopy in a readable way, open both to those inexperienced in the technique, and also to practising electron microscopists. The coverage has been brought completely up to date, whilst retaining descriptions of early classic techniques. Currently live topics such as computer control of microscopes, energy-filtered imaging, cryo- and environmental microscopy, digital imaging, and high resolution scanning and transmission microscopy are all described. The highly praised case studies of the first edition have been expanded to include some interesting new examples. This indispensable guide to electron microscopy, written by an author with thirty years practical experience, will be invaluable to new and experienced electron microscopists in any area of science and technology.
