Book Description
Almost all life depends on light for its survival. It is the ultimate basis for the food we eat (photosynthesis), and many organisms make use of it in basic sensory mechanisms for guiding their behaviour, be it through the complex process of vision, or by the relatively more simple photosens itivity of microorganis~urthermore, light has profound implications for the field of medicine, both as a cause of disease (ie UV damage of DNA), and as a therapeutic agent (ie photodynamic therapy). These and other processes are the basis for the science of photobiolog~ which could be defined as the study of the effects of (visible and ultraviolet) light (from both the sun and artificial sources) on living matter. By its very nature, therefore, it is a multidisciplinary science involving branches of biology, chemistry, physics and medicine. This book contains a selection of papers which have been chosen to highlight recent advances in the various disciplines that make up photo biology. Although no book on photobiology can hope to be comprehensive, we hope that this volume includes a representative sample of much of what is new in the field. It is, however, inevitable that some areas will be better represented than others reflecting the biases of conference org anisers and editors.

Book Description
There are probably few people who do not dream of the good old times, when do ing science often meant fascination, excitement, even adventure. In our time, do ing science involves often technology and, perhaps, even business. But there are still niches where curiosity and fascination have their place. The subject of this book, technological as its title may sound, is one of the fortunate examples. It will report on lasers generating the coldest places in the Universe, and on table top laser microtools which can produce a heat "inferno" as it prevails in the interior of the Sun, or simulate, for specific plant cells, microgravity of the space around our plan et Earth. There will be some real surprises for the reader. The applications range from basic studies of the driving forces of cell division (and thus life) via genetic modification of cells (for example, for plant breeding) to medical applications such as blood cell analysis and finally in vitro fertilization. What are these instruments: laser microbeams and optical tweezers? Both are lasers coupled with a fluorescence microscope. The laser microbeam uses a pulsed ultraviolet laser. Light is focused, as well as possible, in space and time, in order to obtain extremely high light intensities - high enough to generate, for a very short instant, extremely hot spots which can be used to cut, fuse or perforate biological material.

Book Description
The production of biological light (ultra-weak photon emission or biophotons) within many types of cells and tissues is characteristic of an alive organism. You will begin a journey of discovery about biophotons in relationship to biological matter and about how such biophotons can be detected utilizing specialized very photon-sensitive technologies. In this book, Roeland Van Wijk provides a unified synthesis that facilitates easy entry into an exciting sub-field of biology. Light in Shaping Life encompasses the history of biophoton research, insight into how biophotons are generated, and into their involvement with life. Also included, is an overview of the potential benefits of such research to a better understanding of health and medicine. There is sequel to Light in Shaping Life available: Biophoton Technology in Energy and Vitality Diagnostics A Multi-disciplinary, Systems biology, and Biotechnology Appraoch Roeland van Wijk, Yu Yan and Eduard van Wijk Meluna, 2017 ISBN 9789081884341

Optical Interferometry for Biology and Medicine

Book Description
This book presents the fundamental physics of optical interferometry as applied to biophysical, biological and medical research. Interference is at the core of many types of optical detection and is a powerful probe of cellular and tissue structure in interfererence microscopy and in optical coherence tomography. It is also the root cause of speckle and other imaging artefacts that limit range and resolution. For biosensor applications, the inherent sensitivity of interferometry enables ultrasensitive detection of molecules in biological samples for medical diagnostics. In this book, emphasis is placed on the physics of light scattering, beginning with the molecular origins of refraction as light propagates through matter, and then treating the stochastic nature of random fields that ultimately dominate optical imaging in cells and tissue. The physics of partial coherence plays a central role in the text, with a focus on coherence detection techniques that allow information to be selectively detected out of incoherent and heterogeneous backgrounds. Optical Interferometry for Biology and Medicine is divided into four sections. The first covers fundamental principles, and the next three move up successive scales, beginning with molecular interferometry (biosensors), moving to cellular interferometry (microscopy), and ending with tissue interferometry (biomedical). An outstanding feature of the book is the clear presentation of the physics, with easy derivations of the appropriate equations, while emphasizing "rules of thumb" that can be applied by experimental researchers to give semi-quantitative predictions.

Book Description
This book is structured by two-level presentation including a simple descriptive treatment and slightly more in-depth discussions of specific topics. The first-level treatment covers the notions, terminology and techniques that are required to use a synchrotron facility. The book is therefore an ideal first step for all those beginning to use synchrotron light for their work or are considering it. The treated topics include the basic functioning mechanisms of synchrotrons and free electron lasers a description of sychrotron-based techniques in x-ray imaging and radiology, spectroscopy, microscopy and spectromicroscopy, EXAFS, crystallography and scattering, and microfabrication.
