Nano Technology: A Microscopic Solution

The essence of nanotechnology is the ability to work at the molecular level, atom by atom, to create large structures with fundamentally new molecular organization. Nanotechnology is concerned with materials and systems whose structures and components exhibit novel and significantly improved properties. These physical, chemical, and biological properties, processes and phenomena are novel due to their nanoscale size in the range of about 10-9 to 10-7 m (1,000 times smaller than the diameter of human hair). The aim is to exploit these properties by gaining control of structures and devices at atomic, molecular, and supra-molecular levels and to learn to efficiently manufacture and use these devices. New behavior at the nanoscale is not necessarily as predictable as observed at large size scales. The most important changes in behavior are caused not by the order of magnitude size reduction, but by newly observed phenomena intrinsic to the nanoscale, such as size confinement, predominance of interfacial phenomena and quantum mechanics. The objectives of this paper in Nano Technology are the design, modeling, and fabrication of molecular machines, molecular devices and software issues to design kind of devices and machine in Medical field those can help the mankind in proper understanding of diseases pathology and its treatment. The design and modeling of molecular machines is, however, quite feasible with present technology. More to the point, such modeling is a cheap and easy way to explore the truly wide range of molecular machines that are possible, allowing the rapid evaluation and elimination of obvious dead ends and the retention and more intensive analysis of more promising designs. It is clear that the right computational support will substantially reduce the development time. With appropriate molecular computer aided design software, molecular modeling software and related tools, we can plan the development of molecular manufacturing systems on a computer. The current Nano Design software architecture is a set of C++ classes with a tcl front end for interactive molecular gear design. We envision a future architecture centered on an object oriented database of molecular machine components and systems with distributed access via CORBA from a user interface based on a WWW universal client to eventually enable a widely disbursed group to develop complex simulated molecular machines.
