Molecular nanotechnology ("MNT") is an anticipated manufacturing technology that would allow precise control and positional assembly of molecule-sized building blocks through the use of nano-scale manipulator arms. Molecular nanotechnology is usually considered distinct from the more inclusive term "nanotechnology", which is now used to refer to a wide range of scientific or technological projects that focus on phenomena or properties of the nanometer scale (around 0.1-100nm). Nanotechnology is already a blossoming field, but molecular nanotechnology - the goal of productive, molecular-scale machine systems - is still in the preliminary research stage.\n\nNanotechnology was first introduced in 1959, in a talk by the Nobel Prize-winning physicist Richard Feynman, entitled "There's Plenty of Room at the Bottom". Feynman proposed using a set of conventional-sized robot arms to construct a replica of themselves, but one-tenth the original size, then using that new set of arms to manufacture an even smaller set, and so on, until the molecular scale is reached. If we had many millions or billions of such molecular-scale arms, we could program them to work together to create macro-scale products built from individual molecules - a "bottom-up manufacturing" technique, as opposed to the usual technique of cutting away material until you have a completed component or product - "top-down manufacturing".\n\nFeynman's idea remained largely undiscussed until the mid-80s, when the MIT-educated engineer K. Eric Drexler published "Engines of Creation", a book to popularize the potential of molecular nanotechnology. Because MNT would allow manufacturers to fabricate products from the bottom up with precise molecular control, a very wide range of chemically possible structures could be created. Since MNT systems could put every molecule in its specific place, molecular manufacturing processes could be very clean and efficient. Also, because every little bit of matter in an molecular nanotechnology system would be part of a nano-scale manipulator, nanotechnological systems could be far more productive and maintain much higher throughputs than modern manufacturing techniques, which use macro-scale manipulators to fabricate products.\n\nTo initiate an MNT revolution would require an "assembler" - a reprogrammable nano-scale manipulator capable of creating a wide range of molecular structures, including a complete copy of itself. The first assemblers will only function effectively in lab-controlled environments, such as a vacuum. The advent of self-replicating molecular nanomachines could quickly lead to "desktop nanofactories", tabletop appliances that consume modest amounts of power and contain the software required to manufacture an interesting range of useful products. The arrival of MNT would revolutionize wide sectors of human activity, including manufacturing, medicine, scientific research, communication, computing, and warfare. When full-blown molecular nanotechnology will arrive is currently unknown, but many experts foresee its arrival between 2010 and 2020.\n\n\nNANOTECHNOLOGY INTRODUCTION\nWhat is Nanotechnology?\nLast Updated: Tuesday, 03-May-2005 16:46:15 PDT \nThe term "nanotechnology" has evolved over the years via terminology drift to mean "anything smaller than microtechnology," such as nano powders, and other things that are nanoscale in size, but not referring to mechanisms that have been purposefully built from nanoscale components. See our "Current Uses" page for examples. This evolved version of the term is more properly labeled "nanoscale bulk technology," while the original meaning is now more properly labeled "molecular nanotechnology" (MNT), or "nanoscale engineering," or "molecular mechanics," or "molecular machine systems," or "molecular manufacturing

Basically, it is tagging the substance to be delivered to an incredibly tiny particle of gold; usually, there is an antibody (or other targeting substance) attached to the gold particle as well, to target a specific cell type or cellular structure.  It is the antibody that does the targeting; the gold nanoparticle is but the (essentially passive) tool used to carry the targeting molecule and the drug molecule.\n\nIt's one of the developing technologies--it's far from being routine, yet, last I heard.

Do you have an MD? What other scientific background do you have? What country are you in? \n\nIf you have an MD, I would suggest you apply for a PhD, so you can be an MD/PhD. That would put you in a very powerful position. I would look for graduate programs exploring the medical implications of nanotechnology.

Because of the small size nano technology will help in making medicine/curing tools that is small enough to  flow in the blood streams and only kill harmful cells instead of healthy cells.This help not only physically but also mentalli because people doesn't really have to deal with that much of phisical pain such as injected , cut by surgery knifes etc but instead swallowing the necessary cure and thus aiding a much faster recovery.\nNanotechnology tools might also be used to study germs and how our immune system affect it whether inside our body or on the germs body concerned.

Here you have a free downloable PDF presentation from the 28 Sep 05 Conference Micro & Nano Technology (MNT) Measurement Club. I think it's worth to have a look.\n\n"Measuring Nanoparticle Surface Area and Porosity by Gas Sorption"\nMike Tucker, Quantachrome UK\nThe technique of gas sorption has long been used for the determination of surface area and pore size distribution of particulate systems and porous solids. While traditional sorption systems have proved adequate for the majority of tasks, the latest generation of ultra-fine materials, often coupled with microporosity offer new challenges to the sorption scientist. To meet these challenges many new developments have been made in the fields of analytical instrumentation and software modelling. The presentation will review some of the new techniques available, and provide examples to illustrate their applicability to the field of nanotechnology.\nDownload presentation: http://www.npl.co.uk/php/docs/download.php?area=metrology_clubs&path_name=/metrology_clubs/mnt/meetings/28sep05/presentations/connagh.pdf

Nanomedicine is the preservation and improvement of human health using molecular tools and molecular knowledge of the human body.\nNanomedicine, an offshoot of nanotechnology, refers to highly specific medical intervention at the molecular scale for curing disease or repairing damaged tissues, such as bone, muscle, or nerve. A nanometer is one-billionth of a meter, too small to be seen with a conventional lab microscope. It is at this size scale – about 100 nanometers or less – that biological molecules and structures inside living cells operate. \nNanomedicine is the medical application of nanotechnology and related research. It covers areas such as nanoparticle drug delivery and possible future applications of molecular nanotechnology (MNT) and nanovaccinology.\nPlease try sites below, especially the last one.\nGood luck.

"nano" is  a word like "dance".  Aside from size, there are many different expressions of it. For instance, getting a string of DNA to bend on command is a recent accomplishment in nano-tech.  Does that have an immediate application to medicine? No. Does it tell us a little about the behavior of DNA? Yes. This world can change faster now than any other time in history, so I'm not about to make a hard decision on the future.\n\nYou get a great big quantum MAYBE from me on your question.

nanotechnology\nThe science of developing materials at the atomic and molecular level in order to imbue them with special electrical and chemical properties. Nanotechnology, which deals with devices typically less than 100 nanometers in size, is expected to make a significant contribution to the fields of computer storage, semiconductors, biotechnology, manufacturing and energy.\n\nEnvisioned are all kinds of amazing products, including extraordinarily tiny computers that are very powerful, building materials that withstand earthquakes, advanced systems for drug delivery and custom-tailored pharmaceuticals as well as the elimination of invasive surgery, because repairs can be made from within the body.\n\nLarry Bock, CEO of Nanosys, who helped launch more than a dozen successful biotech companies in his career, believes that nanotech will impact even more industries than biotech. In an excerpted article from the March 2003 Nanotech Report, he compared nanotechnology with the microelectronics industry. Bock said that "a single chemistry graduate student can create novel devices and device architectures not even imaginable or manufacturable by today's biggest microprocessor companies. That is because these devices are fabricated chemically, or from the bottom up. Existing microelectronics technology is fabricated by etching wafers, or from the top down."

Nanotechnology\n\nTechnology development at the atomic, molecular, or macromolecular range of approximately 1-100 nanometers to create and use structures, devices, and systems that have novel properties.\n\nOr to put it another way\n\nNanotechnology is a catch-all phrase for materials and devices that operate at the nanoscale. In the metric system of measurement, “Nano” equals a billionth and therefore a nanometer is one-billionth of a meter. References to nano materials, nanoelectronics, nano devices and nanopowders simply mean the material or activity can be measured in nanometers. To appreciate the size, a human red blood cell is over 2,000 nanometers long, virtually outside the nanoscale range!\n \n  \n \nRecently, government and private institutions have devoted substantial research into finding potential valuable uses at this scale, as discussed below.
