Abstract
This paper objectives in Nano Technology are the design, modeling, and fabrication ofmolecular machines, molecular devices and soft ware issues to design that kind of devices and machines. While the ultimate objective must clearly be economical fabrication, present capabilities preclude the manufacture of any but the most basic molecular structures. 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.
Introduction
It is becoming increasingly accepted that we will, eventually, develop the ability to economically fabricate a truly wide range of structures with atomic precision. This will be of major economic value. Most obviously a molecular manufacturing capability will be a prerequisite to the construction of molecular logic devices. The continuation of present trends in computer hardware depends on the ability to fabricate ever smaller and ever more precise logic devices at ever decreasing costs. The limit of this trend is the ability to fabricate molecular logic devices and to connect them in complex patterns at the molecular level. The manufacturing technology needed will, almost of necessity, be able to economically manufacture large structures (computers) with atomic precision (molecular logic elements). This capability will also permit the economical manufacture of materials with properties that border on the limits imposed by natural law. The strength of materials, in particular, will approach or even exceed that of diamond. Given the broad range of manufactured products that devote substantial mass to load-bearing members, such a development by itself will have a significant impact. A broad range of other manufactured products will also benefit from a manufacturing process that offers atomic precision at low cost.Given the promise of such remarkably high payoffs it is natural to ask exactly what such systems will look like, exactly how they will work, and exactly how we will go about building them.
NANO TECHONOLOGY IN CHIP MAKING
Nanotech method for making microchip components which it says should enable electronic devices to continue to get smaller and faster. Current techniques use light to help etch tiny circuitry on a chip, but IBM is now using molecules that assemble themselves into even smaller patterns. Because the technology is compatible with existing manufacturing tools, it should be inexpensive to introduce. IBM says it hopes to pilot the nanotech process in about three to five years. The company's researchers used the novel approach to make part of a device that acts as a type of flash memory, which retains recent information when an electronic gadget is turned off. Such memory is commonly found in handheld computers, mobile phones and digital cameras. At the moment, for example, microchip circuitry is put on silicon wafers using a lithographic process in which the image of the design of how the wires are to be laid out is first projected on to the prepared wafers. With the new technique, it is the polymer patterns that provide the initial stencil - in this instance, for the crystalline array used to make the flash memory.
NANO TECHNOLOGY IN MEDICINE
It will deal with the problems involved in designing and building a micro-scale robot that can be introduced into the body to perform various medical activities. The preliminary design is intended for the following specific applications:
Tumors. We must be able to treat tumors; that is to say, cells grouped in a clumped mass. The specified goal is to be able to destroy tumorous tissue in such a way as to minimize the risk of causing or allowing a recurrence of the growth in the body.
Arteriosclerosis. This is caused by fatty deposits on the walls of arteries. The device should be able to remove these deposits from the artery walls. This will allow for both improving the flexibility of the walls of the arteries and improving the blood flow through them
Blood clots. The cause damage when they travel to the bloodstream to a point where they can block the flow of blood to a vital area of the body. This can result in damage to vital organs in very short order. By using a microrobot in the body to break up such clots into smaller pieces.
