Book Description
Several previous Advanced Study Institutes have concentrated on the techniques of light scattering, while the biological appli cations were not fully explored. Many of the techniques are now standardised and are being applied to a wide range of biologically significant problems both in vivo and in vitro. While laser light scattering methods are superior to conventional methods, there was a general reluctance among biologists to adopt them because of the complexity of the physical techniques and the accompanying mathe matical analysis. Consequently valuable opportunities for advancing the understanding of the biological problems were being missed. Advances in the design and commercial availability of standard light scattering instruments, and the availability of standard computer programs, made the more widespread use of these techniques a practical reality for the biologist. While biologists are unable to cope with the complexities of the physical techniques, physicists are generally unaware of the nature and scale of the biological problems. The meeting at Maratea was an attempt to bring these two groups together and provide an impetus for the application of laser light scattering techniques to biology. This volume differs from the three previous proceedings on laser light scattering in the NATO ASI series (B3, B23, B73), in that it has been published in the Life Sciences series rather than the Physics series, reflecting the shift in emphasis from the development of a new technique to its application in biology.

Book Description
Laser Light Scattering: Basic Principles and Practice, Second Edition deals with the technical aspects of laser light scattering, including the basic principles and practice. Topics covered include light scattering theory, optical mixing spectrometry, photon correlation spectroscopy, and interferometry. Experimental methods and methods of data analysis are also described. This book is comprised of eight chapters and begins with a discussion on the interrelationship between laser light scattering and other types of scattering techniques that use X-rays and neutrons, with particular reference to momentum and energy transfers as well as time-averaged and time-dependent scattered intensity. The spectrum of scattered light and a single-particle approach to time-averaged scattered intensity are considered. The following chapters focus on photoelectric detection of the scattered electric field; optical mixing spectrometers; basic equations for photon correlation spectroscopy; and the principles of Fabry-Perot interferometry. The pertinent features of the experimental aspects of laser light scattering are also outlined, together with the Laplace inversion problem. The final chapter examines polymer molecular-weight distributions in relation to particle sizing. This monograph will be of interest to physicists.

Book Description
Optical Techniques in Biological Research discusses the fundamentals and applications of light scattering, Raman scattering, Fourier transform infrared spectroscopy, nanosecond fluorescence spectroscopy, and circular dichroism. Electron microscopy is also included owing to some of its classical similarity to optical microscopy optical structural and resonance techniques for biological research. The chapters are aimed at a level such that only a general understanding of chemistry and biology is required. The objective is to present material in a way that allows the research worker to assess quickly the applicability, utility, and significance of the specific technique to his or her problem or field of interest. Together with Structural and Resonance Techniques in Biological Research, this book marks the introduction of a new series of volumes, Physical Techniques in Biology and Medicine, which is intended to replace a previous treatise, Physical Techniques in Biological Research.

Book Description
This important volume contains selected papers and extensive commentaries on laser trapping and manipulation of neutral particles using radiation pressure forces. Such techniques apply to a variety of small particles, such as atoms, molecules, macroscopic dielectric particles, living cells, and organelles within cells. These optical methods have had a revolutionary impact on the fields of atomic and molecular physics, biophysics, and many aspects of nanotechnology. In atomic physics, the trapping and cooling of atoms down to nanokelvins and even picokelvin temperatures are possible. These are the lowest temperatures in the universe. This made possible the first demonstration of Bose–Einstein condensation of atomic and molecular vapors. Some of the applications are high precision atomic clocks, gyroscopes, the measurement of gravity, cryptology, atomic computers, cavity quantum electrodynamics and coherent atom lasers. A major application in biophysics is the study of the mechanical properties of the many types of motor molecules, mechanoenzymes, and other macromolecules responsible for the motion of organelles within cells and the locomotion of entire cells. Unique in vitro and in vivo assays study the driving forces, stepping motion, kinetics, and efficiency of these motors as they move along the cell's cytoskeleton. Positional and temporal resolutions have been achieved, making possible the study of RNA and DNA polymerases, as they undergo their various copying, backtracking, and error correcting functions on a single base pair basis. Many applications in nanotechnology involve particle and cell sorting, particle rotation, microfabrication of simple machines, microfluidics, and other micrometer devices. The number of applications continues to grow at a rapid rate. The author is the discoverer of optical trapping and optical tweezers. With his colleagues, he first demonstrated optical levitation, the trapping of atoms, and tweezer trapping and manipulation of living cells and biological particles. This is the only review volume covering the many fields of optical trapping and manipulation. The intention is to provide a selective guide to the literature and to teach how optical traps really work. Contents:Optical LevitationTrapping of Atoms and Biological Particles in the 1980–1990 DecadeUse of Optical Tweezers to Study Single Motor MoleculesOrigin of Tweezer Forces on Macroscopic Particles Using Highly Focused BeamsRotation of Particles by Radiation PressureMicrochemistryUses of Slow AtomsRole of All-Optical Traps and MOTs in Atomic PhysicsFeshbach ResonancesVortices and Frictionless Flow in Bose–Einstein CondensatesTrapped Fermi Gasesand other papers Readership: Researchers and students of atomic physics, molecular physics, biophysics and nanotechnology; historians of science.
