Nanotechnology has been a hot topic in the hacker subculture\never since the term was coined by K. Eric Drexler in his book\n"Engines of Creation", where he predicted that nanotechnology\ncould give rise to replicating assemblers, permitting an\nexponential growth of productivity and personal wealth.\n(there's an authorized\ntranscription at `http://www.foresight.org/EOC/index.html.'). See\nalso blue goo, gray goo, nanobot.

SUB-CATEGORIES OF BIOTECHNOLOGY:\n\nRED BIOTECHNOLOGY is biotechnology applied to medical processes. Some examples are the designing of organisms to produce antibiotics, and the engineering of genetic cures to cure diseases through genomic manipulation.\n\nWHITE BIOTECHNOLOGY, also known as GREY BIOTECHNOLOGY, is biotechnology applied to industrial processes. An example is the designing of an organism to produce a useful chemical. White biotechnology tends to consume less in resources than traditional processes when used to produce industrial goods.\n\nGREEN BIOTECHNOLOGY is biotechnology applied to agricultural processes. An example is the designing of an organism to grow under specific environmental conditions or in the presence (or absence) of certain agricultural chemicals. One hope is that green biotechnology might produce more environmentally friendly solutions than traditional industrial agriculture. An example of this is the engineering of a plant to express a pesticide, thereby eliminating the need for external application of pesticides. Whether or not green biotechnology products such as this are ultimately more environmentally friendly is a topic of considerable debate.\n\nBIOINFORMATICS is an interdisciplinary field which addresses biological problems using computational techniques. The field is also often referred to as computational biology. It plays a key role in various areas like functional genomics, structural genomics, and proteomics amongst others, and forms a key component in biotechnology and pharmaceutical sector.\n\nThe term BLUE BIOTECHNOLOGY has also been used to describe the marine and aquatic applications of biotechnology, but its use is relatively rare.

Nanotechnology comprises technological developments on the nanometer scale, usually 0.1 to 100 nm (1/1,000 µm, or 1/1,000,000 mm). \nNanotechnology covers a wide range of industries, and therefore the potential benefits are also widespread. Telecommunications and Information technology could benefit in terms of faster computers and advanced data storage.\n\nFor the near-term, critics of nanotechnology point to the potential toxicity of new classes of nanosubstances that could adversely affect the stability of cell membranes or disturb the immune system when inhaled, digested or absorbed through the skin.\ninformation taken from the following link:(also, go there for additional info)

hmm, there are lots of different options.\nI did a project on cancer radiation therapies with focus on the biological aspects of the efficacy of radiation (i.e. cell death).\nLast year i did a bionic eye presentation that had people who were blind from birth seeing black dots on a white field (but they didn't have depth perception).  It was fascinating - they had glasses hooked up to the patient and wires connected to a computer (worn on the belt) that further connected directly to the visual cortex of his brain via a cable "plugged" into his neck.\n\nWhat about nanotechnology for curing diseases in the blood?

Stem cell research and cloning are still "blockbusters", but specific antibody research, gene therapy and advanced imaging techniques (fret, for example) are hot too.\n\nOff course, I would certainly add RNA interference to the list!

~ genetic engineering of food, especially for third world countries, and replacing lost vitamins, minerals, etc.\n~ DNA fingerprinting, DNA polymerase, for crime scene investigations\n~ Scientists are now able to clone virtually anything to improve the desired characteristics. For example, genetically engineered animals like pigs are now being tried out to include omega 3 fatty acids for all those meat lovers. (Pigs have more omega 6 fatty acids originally.)\n~ There are so many more values of genetic engineering. You need to do some research on this. Try looking on the web, or in your school textbook (i.e. Biotechnology Unit). It is a hotly debated topic, so its scope is extremely wide. \nGood luck!!! :)\n\n*ANON*

Biotechnology is a technology based on biology, especially when used in agriculture, food science, and medicine.\n\nOf the many different definitions available, the one formulated by the UN Convention on Biological Diversity is one of the broadest:\n\n"Biotechnology means any technological application that uses biological systems, living organisms, or derivatives thereof, to make or modify products or processes for specific use." (Article 2. Use of Terms) \nBiotechnology can also be defined as the manipulation of organisms to do practical things and to provide useful products.\n\nOne section of biotechnology is the directed use of organisms for the manufacture of organic products (examples include beer, milk products, and skin). Naturally present bacteria are utilized by the mining industry in bioleaching. Biotechnology is also used to recycle, treat waste, clean up sites contaminated by industrial activities (bioremediation), and produce biological weapons.

a hybrid between biological/electronic technology enabling our brains to communicate directly with implanted computers, eventually in our own language. \n\nI also think anti-ageing genetic modification is on the horizon, but i fear this development. The slower people age, the longer they are going to live & our resources, both natural & financial are going to be stretched to breaking point.

There is a paper on an experiment they did, which ends with "Finally, we may conclude that we are apparently able to cure mammary adenocarcinoma in experimental mice on demand."\n\nThe paper is at the site below looks right to me, although I can't explain how it is possible.

Applications of Genetic ENGINEERING\n\nThe first Genetically Engineered drug was human insulin approved by the USA's FDA in 1982 [1]. Another early application of GE was to create human growth hormone as replacement for a drug that was previously extracted from human cadavers. In 1986 the FDA approved the first genetically engineered vaccine for humans, for hepatitis B[2]. Since these early uses of the technology in medicine the use of the GE has expanded to supply many drugs and vaccines.\n\nOne of the best known applications of genetic engineering is that of the creation of genetically modified organisms (GMOs).\n\nThere are potentially momentous biotechnological applications of GM, for example oral vaccines produced naturally in fruit, at very low cost.\n\nA radical ambition of some groups is human enhancement via genetics, eventually by molecular engineering. See also: transhumanism.\n\nDNA sequencing is a technique which is used to identify each base in DNA. Although the costs of DNA sequencing has dropped dramatically, the NIH estimates it costs at least $10 million to sequence 3 billion base pairs [3] - the size of the whole human genome.\n\n[edit]\nGenetic Engineering and Research\nAlthough there has been a tremendous revolution in the biological sciences in the past twenty years, there is still a great deal that remains to be discovered. The completion of the sequencing of the human genome, as well as the genomes of most agriculturally and scientifically important plants and animals, has increased the possibilities of genetic research immeasurably. Expedient and inexpensive access to comprehensive genetic data has become a reality, with billions of sequenced nucleotides already online and annotated. Now that the rapid sequencing of arbitrarily large genomes has become a simple, if not trivial affair, a much greater challenge will be elucidating function of the extraordinarily complex web of interacting proteins, dubbed the proteome, that constitutes and powers all living things. Genetic engineering has become the gold standard in protein research, and major research progress has been made using a wide variety of techniques, including:\n\nLoss of function, such as in a knockout experiment, in which an organism is engineered to lack the activity of one or more genes. This allows the experimenter to analyze the defects caused by this mutation, and can be considerably useful in unearthing the function of a gene. It is used especially frequently in developmental biology. A knockout experiment involves the creation and manipulation of a DNA construct in vitro, which, in a simple knockout, consists of a copy of the desired gene which has been slightly altered such as to cripple its function. The construct is then taken up by embryonic stem cells, where the engineered copy of the gene replaces the organism's own gene. These stem cells are injected into blastocysts, which are implanted into surrogate mothers. Another method, useful in organisms such as Drosophila (fruit fly), is to induce mutations in a large population and then screen the progeny for the desired mutation. A similar process can be used in both plants and prokaryotes. \nGain of function experiments, the logical counterpart of knockouts. These are sometimes performed in conjunction with knockout experiments to more finely establish the function of the desired gene. The process is much the same as that in knockout engineering, except that the construct is designed to increase the function of the gene, usually by providing extra copies of the gene or attracting more frequent transcription. \n'Tracking' experiments, which seek to gain information about the localization and interaction of the desired protein. One way to do this is to replace the wild-type gene with a 'fusion' gene, which is a juxtaposition of the wild-type gene with a reporting element such as Green Fluorescent Protein (GFP) that will allow easy visualization of the products
