Physical Techniques in Biological Research, Second Edition, Volume I, Part A: Optical Techniques focuses on the methods and theory applied to relatively pure preparations of biological substances that are derived from cells or other tissue elements. This book covers a wide variety of nonoptical techniques. Organized into five chapters, this edition begins with an overview of the fundamental principles of operation of optical instruments that can be explained in terms of the simple operations of lenses or light rays. This text then examines the limits imposed on direct observation, either through an optical instrument or with the unaided eye, by the nature of light itself. Other chapters consider the potential of certain other microprobe methods. This book discusses as well the process of molecular spectroscopy. The final chapter deals with optical rotation and its dependence on wavelength. This book is a valuable resource for biologists, scientists, physicists, physical chemists, and research workers.

Physical Techniques in Biological Research, Volume III: Cells and Tissues focuses on physical techniques applied to the study of cells, determining the morphology, chemical characteristics, and functions of the cellular organelles. This book discusses the microtomy and postdrying treatment of tissues, phase contrast and interference microscopy in cytology, and fluorescence microscopy. The electron microscopy of microorganisms, ultrastructure of layered lipoprotein structures, and techniques for the mass isolation of cellular components are also elaborated. This publication likewise covers the microphotometry with visible light, ultraviolet absorption techniques, and stereoscopic techniques in X-ray microscopy.Other topics include the birefringence and dichroism of cells and tissues, autoradiography at the cellular level, and manometric techniques for single cells. This volume is a good source for biologists and specialists concerned with the study of cells and tissues.

Physical Techniques in Biological Research, Volume I: Optical Techniques focuses on improvements in physical techniques used in biological research on cells and tissues. The selection first discusses photochemistry and luminescence and light scattering, including applications of luminescence, theory of light scattering and its applications, and light scattering apparatus. The text then examines absorption spectroscopy, ultraviolet absorption spectrophotometry, and infrared spectrophotometry. Discussions focus on factors involved in data gathering, empirical correlation between molecular structure and absorption spectra, buffers for ultraviolet absorption spectrophotometry, instrumentation and techniques, and interpretation of data. The text ponders on the light microscope and phase and interference microscopy, as well as the optical and mechanical systems of microscopes; wave nature of light and its consequences; purposes of phase and interference microscopy; and principles of phase microscopy. The publication also reviews birefringence and dichroism and electron microscopy. The selection is highly recommended for students and readers interested in the physical techniques used in biological research.
