NANO TECHNOLOGY
CRITICAL ENDEAVOR IN CANCER

ABSTRACT

The advent of nanotechnology in cancer research couldn’t have come at a more opportune time. The vast knowledge of cancer genomics and proteomics emerging as a result of the Human Genome Project is providing critically important details of how cancer develops, which, in turn, creates new opportunities to attack the molecular underpinnings of cancer. However, scientists lack the technological innovations to turn promising molecular discoveries into benefits for cancer patients. It is here that nanotechnology can play a pivotal role, providing the technological power and tools that will enable those developing new diagnostics, therapeutics, and preventives to keep pace with today’s explosion in knowledge.

Nanotechnology provides the sized materials that can be synthesized and function in the same general size range and Biologic structures. Attempts are made to develop forms of anticancer therapeutics based on nanomaterials. Dendritic polymer nanodevices serves as a means for the detection of cancer cells, the identification of cancer signatures, and the targeted delivery of anti-cancer therapeutics (cis-platin, methotrexate, and taxol) and contrast agents to tumor cells. Initial studies documented the synthesis and function of a targeting module, several drug delivery components, and two imaging/contrast agents. Analytical techniques have been developed and used to confirm the structure of the device. Progress has been made on the specifically triggered release of the therapeutic agent within a tumor using high-energy lasers. The work to date has demonstrated the feasibility of the nano-device concept in actual cancer cells in vitro.

CRYONICS

CRYONICS ON WAY TO RAISING THE DEAD? (NANO TECHNOLOGY)

Abstract:

Today technology plays a vital role in every aspect of life. Increasing standards in technology in many fields , has taken man today to high esteem. But the present available technologies are unable to interact with the atoms, such a minute particles. Hence Nanotechnology has been developing. Nanotechnology is nothing but a technology which uses atoms with a view to creating a desired product. It has wider applications in all the fields. The
important application is Cryonics.. Cryonics is nothing but an attempt of raising the dead - making them alive. First we preserve the body then by using molecular machines based nanotechnology we could revive the patients by repairing damaged cells.
In this technical paper we would like to discuss cryonics, how the process of cryonics goes on and why nanotechnology is being used and description of molecular machines which has the capability of repairing damaged cells. Therefore Cryonics is an area in which most of the work is to be done in future .

NANO TECHNOLOGY

Abstract

This paper objectives in Nano Technology are the design, modeling, and fabrication of molecular 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, we can plan the development of molecular manufacturing systems on a computer. The current NanoDesign software architecture is a set of C++ classes with a tcl front end for interactive molecular gear design. We envision a future architecture centered around 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.

ABSTRACT

A basic definition of Nanotechnology is the study manipulation and manufacture of extremely minute machines or devices.These devices are so small to the point of manipulating the atoms themselves to form materials.By this Nanotechnology we can make computers billions of times morefull than today’s and new medical capabilities that will heal and cure in cases that are now viewed as utterly hopelessly. The properties of manufactured products depend on how those atoms are arranged.If we know about exactly how many dopant atoms are in a single transdistor and exactly where each individual dopant atom is located and placed roughly the right number in roughly the right place,we can make a working transistor.Another improvement in Nanotechnology is self replication.Self replication make a effective route to truly low cost manufacturing.Our intuitions about self replicating systems learned from biological systems that surround us are likely to seriously mislead us about the properties and characteristics of artificial self replicating systems designed for manufacturing purposes.Artificial systems able to make a wide range of nonbiological products like diamond under programmatic control are likely to be more brittle and less adaptable in their response to changes in their environment than biological systems.At the same time they should be simpler and easier to design.Thus the progress of technology around the world has already given us more precise,less expensive manufacturing technologies that can make an unprecedented diversity of new products.Everything requires the computer is a major reason why people should research and develop Nanotechnology.

Nanorobots

NANOBOTS: THE ARTIFICIAL BLOOD

INTRODUCTION

Robert A. Freitas Jr. visualizes a future "vasculoid" (vascular-like machine) that would replace human blood with some 500 trillion nanorobots distributed throughout the body’s vasculature as a coating. It could eradicate heart disease, stroke, and other vascular problems; remove parasites, bacteria, viruses, and metastasizing cancer cells to limit the spread of bloodborne disease; move lymphocytes faster to improve immune response; reduce susceptibility to chemical, biochemical, and parasitic poisons; improve physical endurance and stamina; and partially protect from various accidents and other physical harm. With the availablitity of mature molecular nanotechnology we could replace blood with a single complex robot. This robot would duplicate all essential thermal and biochemical transport functions of the blood, including circulation of respiratory gases, glucose, hormones, cytokines, waste products, and all necessary cellular components. The device would conform to ! the shape of existing blood vessels. Ideally, it would replace natural blood so thoroughly that the rest of the body would remain, essentially unaffected. It is, in effect, a mechanically engineered redesign of the human circulatory system that attempts to integrate itself as an intimate personal appliance with minimal adaptation on the part of the host human body. Molecular nanotechnology has been defined as the three-dimensional positional control of molecular structure to create materials and devices to molecular precision. The human body is comprised of molecules, hence the availability of molecular nanotechnology will permit dramatic progress in human medical services. Nanomedicine will employ molecular machine systems to address medical problems, and will use molecular knowledge to maintain and improve human health at the molecular scale. Nanobots will have extraordinary and far-reaching implications for the medical profession, for the definition of disease, for the diag! n osis and treatment of medical conditions including aging, and ultimately for the improvement and extension of natural human biological structure and function. "Nanomedicine is the preservation and improvement of human health using molecular tools and molecular knowledge of the human body."
