Conclusion
Full-field XRF microscopy using a color X-ray camera is a powerful tool to quickly image large areas (up to about 100 mm2) with spatial resolution from 50 µm to 5 µm. It is ideally suited to non-destructive study of fragile samples, such as those found in cultural heritage research, and for in situ imaging.

Recent developments in scanning electron microscopy (SEM) have resulted in a wealth of new applications for cell and molecular biology, as well as related biological disciplines. It is now possible to analyze macro molecular complexes within their three-dimensional cellular microenvironment in near native states at high resolution, and to identify specifi c molecu les and their structural and molecular interactions. New approach es include cryo-SEM applications and environmental SEM (ESEM), staining techniques and processing ap plications combining embedding and resin-extraction for imaging with high resolution SEM, and advances in immuno-labeling. With chapters written by experts, this guide gives an overview of SEM and sample processing for SEM, and highlights several advances in cell and molecular biology that greatly benefi ted from using conventional, cryo, immuno, and high-resolution SEM.
New to the Advances in Microscopy and Microanalysis book series! About the series
The Press currently publishes the Microscopy and Microanalysis (MAM) journal in conjunction with the MSA, which reaches 4,000 microscopists and is affi liated with 12 international microscopy societies. The series would be a natural development from this journal, and will take a broad view of the discipline, covering topics from instrumentation to imaging, methodology and analysis across physical science, materials science, biology and medicine. Books commissioned for the series will range from advanced undergraduate textbooks through to research and practitioner oriented monographs for researchers. The series aims to produce a coherent source of material, encouraging the communication and exchange of ideas across these divergent fi elds, ensuring that the series appeals to a broad community in the physical and life sciences.
Forthcoming titles in this series:
Microscopic Nanocharacterization of Materials by Michael Isaacson
Energy Filtered Electron Microscopy and Electron Spectroscopy by Richard Leapman
Dynamic Transmission Electron Microscopy by Nigel Browning, Thomas LaGrange, Bryan Reed, Henning Stahlberg, Bradley Siwick
