Nanotechnology, shortened to "nanotech", is the study of the control of matter on an atomic and molecular scale. Nano science and nanotechnology are recent, revolutionary development in Science and Engineering that are evolving at a very fast pace.[1,2] It is driven by the desire to fabricate materials with novel and improved properties that is likely to impact virtually all areas of the physical and chemical sciences, biological sciences and health sciences. The word ‘nano’ derives from the Greek word ‘nanos’, which means dwarf or extremely small and mathematically, a nanometer is a billionth of a meter or 10-9 m. Particles whose sizes fall in the size range of 1-100 nm is called a nano particles, whether it is dispersed in gaseous, liquid or solid medium. Generally nanotechnology deals with structures of the size 100 nanometers or smaller, and involves developing materials or devices within that size. Nanotechnology is very diverse, ranging from extensions of conventional device physics, to completely new approaches based upon molecular self-assembly, to developing new materials wi...
Amandi Hiyare: Before forming my research question, I had a discussion with my research project coordinator “Lisa Pope” who told me that the Flinders nanotechnology research team has been developing microbial catheters. Then on Monday I had an interview with Professor Joe Shapter who told me that your team was leading this project. So I was wondering whether you would be able to provide me with some detailed information about this innovation?

Nanotechnology is defined as the science of design, synthesis and characterization of matter at the nanoscale, which mesures one billionth of the meter [1,2] On that scale, structures exhibit novel chemical, physical and biological properties and processes, which enables the creation of engineered nanomaterials (ENMs), with various characteristics and potential applications. [3] It’s not just that though. Nanotechnology shows the ability to eliminate the gaps among medicine, material engineering and science, computer technology and public policy, creating new clinical and medical approaches to better diagnose, treat and prevent any kind of illness. In fact, it is already moving from simple passive structures

Nanotechnology is the manipulation of structures at nano levels. It uses incredibly small materials, devices, and systems to manipulate matter. These structures are measured in nanometers, or one billionth of a meter, and can be used by themselves or as part of larg...
In 2000 the Clinton Administration introduced the National Nanotechnology Initiative in the efforts to promote research and development involving nanotechnology ( In 2003 congress enacted 21st Century Nanotechnology Research and Development Act. This act provided a legal base for the National Nanotechnology Initiative to stablish programs, assigned agency responsibilities, funding, and promote research. Currently the National Nanotechnology Initiative consists of individual and collaborative nanotechnology activities of various Federal agencies (National Science and Technology Council, 2014). The National Nanotechnology Initiative creates a framework for shared goals, priorities, and strategies that assist every federal agency participating
In the novel, Prey, written by Michael Crichton it pertains to the subject of nanotechnology throughout the whole entire book. The main characters of this novel are the
Nanotechnology is defined as “ a technology executed on the scale of less than 100 nanometers, the goal of which is to control individual atoms and molecules, especially to create computer chips and other microscopic devices” (Webster’s Dictionary, 1999). In the early 1970’s an MIT student by the name of K. Eric Drexler came up with the idea of manufacturing things, both biological and non-biological, from the molecular level up. Drexler noticed the amazing talents of natural biology and wondered if humans could mimic biology on a mechanical level,
“Nanotechnology is science, engineering, and technology conducted at a nanoscale which is about 1 to 100 nanometers,” according to the National Nanotechnology Initiative. A nanometer is a billionth of a meter, there are 25,400,000 nanometers in an inch and a sheet of newspaper is about 100,000 nanometers thick. Putting that into perspective, if a marble were a nanometer, a meter would be the size of the Earth. Nanotechnology can be used throughout all fields of science, including chemistry, biology, physics, materials science and engineering to study and apply extremely small things. Physicist Richard Feynman introduced the concepts of nanoscience and nanotechnology with his talk titled “There’s Plenty of Room at the
Nanotechnology is a part of a science and a technology abou the control of matter on the atomic and molecular scale. This means things that are about 100 nanometers or smaller. Nanotechnology includes making products that uses part of small, such as electronic devices, sensors, etc… Nanotechnology brings scientist and engineers together from many different subjects, such as applied physics, material science, interface science, device physics, chemistry Supramolecular chemistry and etc… When people talks about nanotechnology, they mean structures of the size is 100 nanometers or smaller. Nanotechnology is a unit that equals to 1 out of a billion. 1 nanometer (nm) is 1 out of a billion, which a hair of 1 out of ten thousand of a ultrafine world. For example, 3 or 4 atoms can fit in there. Furthermore, nanotechnology is small like nanometer making device controlling atoms and molecules by ultrafine technology. First human that made other scientist to lead to the world of nano was Richard Phillips Feynman who got Nobel Prize in Physics
Good morning/ afternoon ladies and gentleman, my name is Gurkaran Banipal, and my presentation is on Carbon Nanotubes or also known as CNTs. Did you know theses nanotubes are constructed with a length-to-diameter ratio of up to 132,000,000:1, significantly larger than for any other material present and they are lighter than plastic, stronger than steel, harder than diamond, and conduct electricity better than copper. Carbon nanotubes are a revolutionary development that has a very distinguished structure and unique properties which allows it to have significant applications in the fields of: nanotechnology, electronics, and other fields of materials science and technology that are applying to our everyday lives and improving them without us even noticing, and have a very small negative impact on our environment compared to their potential contributions to our world. The structure the CNTs possess is so unique and distinct it allows it to have very peculiar properties. The structure of the CNTs allows it to have very unique bonding properties, strength, electrical conductivity and Kinetic properties that are helping to change the world we know. I will discuss all of these properties, but first let me properly introduce you to these aforementioned Carbon Nanotubes.
Since 2000, nanotechnology has been funded by the U.S. government which has created the National Nanotechnology Initiative (NNI) to guide research and monitor its development [1]. Advocators of NNI “assert that nanotechnology is one of the most important emerging and enabling technologies and that U.S. competitiveness, technolo...
Jeremy Rifkin wrote, in his article Biotech Century: Playing Ecological Roulette with Mother Natures Design, "Humans have been remaking the Earth for as long as we have had a history." Well the path of history humans have chosen to take also affects how we remake the Earth. In Neal Stephensons novel, The Diamond Age, one is shown how the technology of the time reshapes the political, economical and educational aspects of history. That technology is the manipulation of molecules into atomic-sized machines called nano-machines. Stephenson brilliantly shows how such a powerful and truly revolutionary technology like nanotechnology could change life, as we now know it, or they in the future know life. Nanotechnology, as nanotechnology exists in The Diamond Age, is well developed and highly used. Matter compilers use nanotechnology to make most mass-produced consumer products, and most matter compilers are powered by resource suppliers called Feeds. Those who control the Feeds control nanotechnology and have a great amount of political and economical power. These same individuals or groups of individuals called phyles usually represent those who hold most the wealth and political sway in the world. That power and wealth then causes the wealthy citizen or phyle to take for granted what they have so well. Such things include the best education, the nicest material possessions, inheritance, and even responsibility. However, what if that same technology that made the privileged, the privileged, was given to the masses, rich or poor, with the tools and talents to implement such technology? In a sense, making that same power that the upper class took for granted a great equalizer for society to play around with. This is w...
