Preface
Preparing a new edition of an originally successful first edition must always
result in a choice having to be made as to what to leave out to make room for
any new material. Optical microscopy has developed very fast in the last ten
years and yet the same principles of achieving a good image by the interaction
of light with the matter under investigation are still there. Developing tech-
niques in confocal and near-field microscopy have been given chapters as have
calcium ion and pH imaging which reflect something of the enormous develop-
ment of fluorochromes and fluorescent microscopy. Video cameras and video
recorders used to record images for visual examination or to lead on to image
analysis by subsequent processing in digital or other format have all made
large contributions to the development of optical microscopy.
Basic optical microscopy in which aspects of resolution of fine detail and the
requirement of contrast to make that small detail visible has been retained.
The recording of the image by wet chemistry methods is still a routine require-
ment in many projects but the use of video cameras and printers is beginning
to challenge the dark-room photochemical production of still images. The
basic immunohistochemistry and that of differential staining particularly in the
preparation of tissues and chromosomes has been retained while new empha-
sis has been given to such topics as fluoroprobes for calcium and pH imaging
and microinjection of materials into living cells.
The use of optical microscopy techniques such as near-field and nanovid
to push the resolution beyond the traditionally accepted diffraction limit
attempts to bridge the gap between optical and electron microscopy. Surface
details of living cells are very important components in the study of drug
reaction and these together with cells to surface contacts are assisted by the
techniques of reflection-contrast microscopy and evanescent illumination.
The editor wishes to thank all the many colleagues, and particularly Dr
Peter Hobson, for their patience in technical discussions. Mr D. J. Thomson is
gratefully acknowledged for his help in many practical ways. Thanks are due to
the production team of OUP who have been so helpful in preparing this book
over a long period.
