what are the future prospects for nanotechnology?

Question

i am doing b.sc biotechnology

Answer 1

To develop novel concepts in nanotechnology for NASA's future needs on electronics, computing, sensors, and advanced miniaturization of all systems;

To develop highly integrated and intelligent simulation environment that facilitates the rapid development and validation of future generation electronic devices as well as associated materials and processes through virtual prototyping at multiple levels of fidelity.
Nanomaterials includes subfields which develop or study materials having unique properties arising from their nanoscale dimensions:
Colloid science has given rise to many materials which may be useful in nanotechnology, such as carbon nanotubes and other fullerenes, and various nanoparticles and nanorods.
Nanoscale materials can also be used for bulk applications; most present commerical applications of nanotechnology are of this flavor.
Headway has been made in using these materials for medical applications; see Nanomedicine.
Bottom-up approaches seek to arrange smaller components into more complex assemblies:
DNA Nanotechnology utilizes the specificity of Watson-Crick basepairing to construct well-defined structures out of DNA and other nucleic acids.
More generally, molecular self-assembly seeks to use concepts of supramolecular chemistry, and molecular recognition in paticular, to cause single-molecule components to automatically arrange themselves into some useful conformation.
Top-down approaches seek to create smaller devices by using larger ones to direct their assembly:
Many technologies descended from conventional solid-state silicon methods for fabricating microprocessors are now capable of creating featres smaller than 100 nm, falling under the definition of nanotechnology. Giant magnetoresistance-based hard drives already on the market fit this description, [2] as do atomic layer deposition (ALD) techniques.
Solid-state techniques can also be used to create devices known as nanoelectromechanical systems or NEMS, which are related to microelectromechanical systems or MEMS.
Functional approaches seek to develop components of a desired functionality without regard to how they might be assembled:
Molecular electronics seeks to develop molecules with useful electronic properties. These could then be used as single-molecule components in a nanoelectronic device. For an example see rotaxane.
Synthetic chemical methods can also be used to create synthetic molecular motors, such as in a so-called nanocar.
Speculative: These subfields seek to anticipate what inventions nanotechnology might yield, or attempt to propose an agenda along which inquiry might progress. These often take a big-picture view of nanotechnology, with more emphasis on its societal implications than the details of how such inventions could actually be created.
Molecular nanotechnology is a proposed approach which involves manipulating single molecules in finely controlled, deterministic ways. This is more theoretical than the other subfields and is beyond current capabilities.

Applications of nanotechnology for treatment, diagnosis, monitoring, and control of biological systems has recently been referred to as "nanomedicine" by the National Institutes of Health. Research into the rational delivery and targeting of pharmaceutical, therapeutic, and diagnostic agents is at the forefront of projects in nanomedicine. These involve the identification of precise targets (cells and receptors) related to specific clinical conditions and choice of the appropriate nanocarriers to achieve the required responses while minimizing the side effects. Mononuclear phagocytes, dendritic cells, endothelial cells, and cancers (tumor cells, as well as tumor neovasculature) are key targets. Today, nanotechnology and nanoscience approaches to particle design and formulation are beginning to expand the market for many drugs and are forming the basis for a highly profitable niche within the industry, but some predicted benefits are hyped. This article will highlight rational approaches in design and surface engineering of nanoscale vehicles and entities for site-specific drug delivery and medical imaging after parenteral administration. Potential pitfalls or side effects associated with nanoparticles are also discussed.

The team of authors of the fine Engines of Creation has succumbed to a premature sequel in this attempt to envision for the general reader an industrial biotechnology revolution. This update of Engines is two-thirds scenarios, most of them cloying "looking back" reports from a near future of nanotechnology. The authors' stated purpose--to prepare a channel of understanding for a molecular-level industrial revolution--is sound, but their answers beg at least half their own questions. A true molecular industry probably lies just below the horizon of popular science reporting; this ceasarean-style report of its birth obscures nanotechnology's future possibilities without clarifying the present science.

From Library Journal
Nanotechnology sounds like a fantasy straight out of Star Wars , but then 50 years ago so did many of the things that we take for granted today--space exploration, computer chips, organ transplants, etc. The term ("Nano" comes from the Greek word meaning "dwarf") refers to "the products and processes of molecular manufacturing, including molecular machinery." The idea of molecular technology was first mentioned in 1959 by Nobel Laureate Richard Feynman, but until fairly recently little was done here. The Japanese, however, forged ahead with research and have built the Nanotechnology Center. Drexler, one of the leading proponents of nanotechnology and author of the only other book on the subject, Engines of Creation ( LJ 6/1/86), offers a fascinating glimpse at this new science that will affect almost every aspect of human existence--environment, agriculture, transportation, communications, medicine, etc. Recommended for academic and public libraries.

Answer 4

Nanorobotics. DARPA (military research) has already put a lot of money in nanorobotics to spy on people or for military intelligence. If you want a bit of information on nanorobotics and especially on robotics buy (this might sound funny ) the book : How To Survive a Robot Uprising : Tips on defending yourself against the coming rebellion by Daniel H. Wilson. It is a pretty funny book but has a lot of information on robotics and a bit of information on nanorobotics. Good Luck ; ]

Answer 5

nanotechnology has a great future as the need of the medical practitioners who can work on small objects is increasing day by day
as human is developing, the diseases are making a large cover around him so in his perspective it has a great future
