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.
"Not everything in medical science has a clear beginning. The first realization of infertility and putative remedies remain shrouded in contextual history, but likely goes back to the dawn of our species, well before there was a written record. Childlessness was, and is still, considered a burden in some communities"--

Microrobotics is an emerging and booming area with many and various applications, including in fields such as industrial/manufacturing robotics, medical robotics, and laboratory instrumentation. Microrobotics for Micromanipulation presents for the first time, in detail, a treatment of the field of robotics dedicated to handling objects of micrometer dimensions. At these dimensions, the behavior of objects is significantly different from the better known, larger scales, which leads to implementation techniques that can be radically different from the more commonly used solutions. This book details the behaviors of objects at the micrometer scale and provides robotics solutions that are suitable, in terms of actuators, grippers, manipulators, environmental perception, and microtechnology. Worked examples are included in the book - enabling engineers, students and researchers to familiarize themselves with this emerging area and to contribute to its development.
In the course of the years since H. D. SCHMIDT, in 1895, describcd his "microscopic dissector," a mechanical device for dissecting and study ing biological materials, a great wealth of information has been pub lished in the scientific and technical literature on methods involving the use of exceedingly delicate microtools mechanically guided under microscopic control for the investigation of microscopic structures and very small amounts of material.. The operative tools used can be moved with considerable precision under various microscopic magnifications to perform the required tasks. With the continuous progress in these methods, hundreds of micro manipulators and other mechanical manipulativc devices, auxiliaryequip ment, and a great diversity of microtools have been described for per forming varied operations on practically any type of materials and test objects. Thus, micromanipulative and related techniques have become innumerable and often intricate, and the applications, formerly confined to certain fields of biology and medicine, have been extended to the most diverse fields of science and technology as mtn be Been from a rapid glance at the contents of the presEmt volume.
Capillary Forces in Microassembly discusses the use of capillary forces as a gripping principle in microscale assembly. Clearly written and well-organized, this text brings together physical concepts at the microscale with practical applications in micromanipulation. Throughout this work, the reader will find a review of the existing gripping principles, elements to model capillary forces as well as descriptions of the simulation and experimental test bench developed to study the design parameters. Using well-known concepts from surface science (such as surface tension, capillary effects, wettability, and contact angles) as inputs to mechanical models, the amount of effort required to handle micro-components is then predicted. Researchers and engineers involved in micromanipulation and precision assembly will find this a highly useful reference for microassembly system design and analysis.
Microbiorobotics is a new engineering discipline that inherently involves a multidisciplinary approach (mechanical engineering, cellular biology, mathematical modeling, control systems, synthetic biology, etc). Building robotics system in the micro scale is an engineering task that has resulted in many important applications, ranging from micromanufacturing techniques to cellular manipulation. However, it is also a very challenging engineering task. One of the reasons is because many engineering ideas and principles that are used in larger scales do not scale well to the micro-scale. For example, locomotion principles in a fluid do not function in the same way, and the use of rotational motors is impractical because of the difficulty of building of the required components. Microrobotics is an area that is acknowledged to have massive potential in applications from medicine to manufacturing. This book introduces an inter-disciplinary readership to the toolkit that micro-organisms offer to micro-engineering The design of robots, sensors and actuators faces a range of techology challenges at the micro-scale. This book shows how biological techniques and materials can be used to meet these challenges World-class multi-disciplanry editors and contributors leverage insights from engineering, mathematical modeling and the life sciences – creating a novel toolkit for microrobotics
This book provides an overview of the noteworthy developments in the field of micromachining, with a specific focus on microinjection systems used for biological micromanipulation. The author also explores the design, development, and fabrication of new mechanical designs for micromachines, with plenty of examples that elucidate their modeling and control. The design and fabrication of a piezoelectric microinjector, constant force microinjector, constant force microgripper, PDVF microforce sensor, and a piezoelectric microsyringe are presented as examples of new technology for microinjection systems. This book is appropriate for both researchers and advanced students in bioengineering.
