  • About 400 years ago, the invention of telescopes and microscopes not only extended our sense of seeing but also revolutionized our perception of the world. Extending this perception further and further has since been the driving force for major scientific developments. Local probe techniques extend our sense of touching into the micro- and nanoworld and in thisway provide complementary newinsight into theseworlds with microscopic techniques.

  • Nanotechnology in Biology and Medicine is intended to serve as an authoritative reference for a wide audience involved in research, teaching, learning, and practice of nanotechnology in life sciences. Nanotechnology, which involves research on and the development of materials and species at length scales between 1 to 100 nm, has been revolutionizing many important scientific fields ranging from biology to medicine. This technology, which is at the scale of the building blocks of the cell, has the potential of developing devices smaller and more efficient than anything currently available.

  • Applications of microelectromechanical systems (MEMS) and microfabrication have spread to different fields of engineering and science in recent years. Perhaps the most exciting development in the application of MEMS technology has occurred in the biological and biomedical areas. In addition to key fluidic components, such as microvalves, pumps, and all kinds of novel sensors that can be used for biological and biomedical analysis and measurements, many other types of so-called micro total analysis systems (TAS) have been developed.

  • The World is confronted with a plethora of potentially disruptive technologies – some, such as nanotechnology, will inevitably challenge our cherished social, economic and industrial stability over the next two decades. Rational design and manufacture of materials properties through nanostructure control will profoundly affect the food we eat, the sources of water and power we use, our health services, our national security, housing, transportation, etc. Precisely what will be the ultimate effect of these disruptions is still unclear.

  • In 1959, Richard P. Feynman, Professor of Physics at the California Institute of Technology and Nobel Laureate, delivered an address at the American Physical Society, which is given the credit for inspiring the field of nanotechnology. Published in Engineering and Science, Feynman’s address entitled “Plenty of Room at the Bottom” described a new field of science dealing with “the problem of manipulating and controlling things on a small scale.

  • The “origin of this species” lies in the pages of the journal Biometrika and precedes the birth of either of the authors. There, in his remarkable landmark 1951 paper “Random dispersal in theoretical populations,” J.G. Skellam made a number of observations that have profoundly affected the study of spatial ecology.

  • There are four reasons why earnings are a poor measure of performance compared to changes in shareholder value. First, unlike cash flow, which underpins SVA, accounting earnings are arbitrary and easily manipulated by management. Different, equally acceptable, accounting methods lead to quite different earnings figures. Prominent examples include alternative ways to compute the cost of goods sold (LIFO versus FIFO), different methods of depreciating assets, and the various choices in accounting for mergers and acquisitions.

  • Information gathered from the remaining intact tropical habitats might seem to deserve special treatment, for such data can be thought to represent precise, finely tuned biological interrelationships. Their evolutionary reason for existence might be revealed simply in their current ecology. Tropical data in general are often deemed more significant than comparable data taken in other habitats. Like the first-mentioned bias, this belief can encourage creative speculation, but sometimes it diminishes the accuracy with which the actual setting of a field study is examined or described....

  • A variety of microbes manipulate the cytoskeleton of mammalian cells to promote their internalization, motility and⁄or spread. Among such bacte-ria, enteropathogenic Escherichia coliand enterohemorrhagic Escherichia coliare closely related pathogens that adhere to human intestinal cells and reorganize the underlying actin cytoskeleton into ‘pedestals’.

  • Microbial pathogens exploit the ubiquitin system to facilitate infection and manipulate the immune responses of the host. In this study, susceptibility to Yersinia enterocolitica and Yersinia pseudotuberculosis invasion was found to be increased upon overexpression of the deubiquitinating enzyme otubain 1 (OTUB1), a member of the ovarian tumour domain-containing protein family.

  • Unfortunately, soon after these first attempts, the designer will find the robot getting stuck on what seem to be innocuous objects or bumps, held captive under a chair or fallen tree trunk, incapable of doing any- thing useful, or with a manipulator that crushes every beer can it tries to pick up. Knowledge of the mechanics of sensors, manipulators, and the concept of mobility will help reduce these problems. This book provides that knowledge with the aid of hundreds of sketches showing drive lay- outs and manipulator geometries and their work envelope.

  • Pituitary gonadotropins, follicle-stimulating hormone (FSH) and luteinizing hormone (LH) play central roles in regulating gametogenesis and the production of gonadal hormones, in fish as in other vertebrates. Pituitary gonadotropins are composed of two non-covalently associated polypeptide subunits, which must be glycosylated, folded, and assembled as a heterodimer to be biologically active.

  • The human body is composed of structures organized in a hierarchical fashion: from biomolecules assembled into polymers, to multimeric assemblies such as cellular organelles, to individual cells, to tissues, to organ systems working together in health and disease- each dominated by a characteristic length scale. Decades of science and engineering are now converging to provide tools that enable the orderly manipulation of biological systems at previously inaccessible, though critically important, length scales (...
