| biology and electronics: Nanobioelectronics - for Electronics, Biology, and Medicine Andreas Offenhäusser, Ross Rinaldi, 2010-11-29 The combination of biological elements with electronics is of great interest for many research areas. Inspired by biological signal processes, scientists and engineers are exploring ways of manipulating, assembling, and applying biomolecules and cells on integrated circuits, joining biology with electronic devices. The overall goal is to create bioelectronic devices for biosensing, drug discovery, and curing diseases, but also to build new electronic systems based on biologically inspired concepts. This research area called bioelectronics requires a broad interdisciplinary and transdisciplinary approach to biology and material science. Even though at the frontier of life science and material science, bioelectronics has achieved in the last years many objectives of scientific and industrial relevance, including aspects of electronics and biotechnology. Although the first steps in this field combined biological and electronic units for sensor applications (e. g. , glucose oxidase on an oxygen electrode), we see now many applications in the fields of genomics, proteomics, and celomics as well as electronics. This approach challenges both the researcher and the student to learn and think outside of their zones of comfort and training. Today, one can fabricate electrically active structures that are commensurate in size with biomolecules. The advancement of nanotechnology has influenced bioelectronics to a large extent. |

| biology and electronics: Electricity and Magnetism in Biology and Medicine Ferdinando Bersani, 2012-12-06 In the last few decades the research on bioelectromagnetics has expanded worldwide. About one thousand researchers are now working in the field in a variety of institutions throughout the world, including medical, biological, engineering, and technical laboratories and protection agencies. After many years of research, a clear picture is now emerging: Initially the research was mainly interested in the therapeutic applications of ELF electric and magnetic fields, and the RF range was mainly taken into consideration with respect to thermal effects only. Then, tne growing body of biological effects of ELF fields on cells and biological tissues (particularly for the repair processes in bone) have drawn the attention of researchers to non-thermal effects, ranging from static fields to microwaves. A specific field of interest that has been the object of a large debate in the last twenty years has been the potential health risk associated with electric power production and distribution and, more recently, with domestic and industrial appliances. In the last few years, the explosion of the market for cellularphones has highlighted the issue of possible health dangers related to their use and to the widespread presence of base stations. The first World Congress on Electricity and Magnetism in Biology and Medicine, was held in Orlando, Florida, in 1992, and collected the widest amount of contributi9ns from almost all the major researchers involved in the field. |

| biology and electronics: Granular Nanoelectronics David K. Ferry, John R. Barker, Carlo Jacoboni, 2013-12-14 The technological means now exists for approaching the fundamentallimiting scales of solid state electronics in which a single carrier can, in principle, represent a single bit in an information flow. In this light, the prospect of chemically, or biologically, engineered molccular-scale structures which might support information processing functions has enticed workers for many years. The one common factor in all suggested molecular switches, ranging from the experimentally feasible proton-tunneling structure, to natural systems such as the micro-tubule, is that each proposed structure deals with individual information carrying entities. Whereas this future molecular electronics faces enormous technical challenges, the same Iimit is already appearing in existing semiconducting quantum wires and small tunneling structures, both superconducting and normal meta! devices, in which the motion of a single eh arge through the tunneling barrier can produce a sufficient voltage change to cut-off further tunneling current. We may compare the above situation with today's Si microelectronics, where each bit is encoded as a very !arge number, not necessarily fixed, of electrons within acharge pulse. The associated reservoirs and sinks of charge carriers may be profitably tapped and manipulated to proviele macro-currents which can be readily amplified or curtailed. On the other band, modern semiconductor ULSI has progressed by adopting a linear scaling principle to the down-sizing of individual semiconductor devices. |
