What is Nanotechnology? “Nanotechnology is the manipulation or self-assembly of individual atoms, molecules, or molecular clusters into structures to create materials and devices with new or vastly different properties. Nanotechnology can work from the top down (which means reducing the size of the smallest structures to the nanoscale… or the bottom up (which involves manipulating individual atoms and molecules into nanostructures and more closely resembles chemistry or biology)” (Joseph & Morrison, 2006, p.3, para. 2).
There are several requirements which are needed to meet the definition of nanotechnology; size limitation of 1-100 nm (or about the width of three or four atoms), and it needs to be man-made. Its purpose is to control matter at a nanoscale, using mechanochemistry to form the desired structure. One of the most important criteria is that the nano-structure has its own unique characteristics that are unlike any other nano-structure. It is required to be unique.
Nanotechnology in essence is not futuristic in nature. Scientists refer to a timeline of the development of nanotechnology. The first wave of nanoparticles would perform one function only. The nanoparticles of the second wave would be able to execute multiple functions. The third wave would be proliferation. Nanotechnology is already applied and used today in cosmetics (sunscreen), coatings (non-scratch surfaces), and to make stronger tools. Short-term applications will most likely include such things as paints. Paints created with nanotechnology could have various properties for multiple applications, e.g. reducing solvent need in paint and thereby making it more environmentally friendly, making paint thinner, which could be used on aircraft. It would reduc...

The small size ranging from 0.1 to 10 micrometres of nanobots make it difficult to be constructed. The process of working atom by atom and molecule by molecule is monotonous work and the miniaturization of synthetic mechanisms to a nanoscale will only be achievable with the advancement of research in metallurgy.
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?

In the article “Pinpointing Cancer Fight,” Liz Szabo states the uses of nanotechnology and how researchers are attempting to use this advancement to fight cancer. She defines that nanotechnology is a type of technology that creates devices on an atomic level; this equipment can allow people such as researchers to use its ability to detect cancerous cells as well as treat them. Szabo remains a neutral tone as she states that while some are against the idea of using nanotechnology since there are many risks, others are optimistic that it may lead to transformational results. She presents a list of some products developed through nanotechnology and explains its usage in addition to mentioning the failure of those nanotech products. Szabo provides
K. Eric Drexler is known to be “the founding father of nanotechnology,” and theorized the creation of mechanical nanoscale systems that would revolutionize the world of manufacturing and technology. However, many opponents of his theory feared the implications and applications of such nanotechnology, and therefore began to spread panic through the concept of the menacing “grey goo.” “Prey” by Michael Crichton delves into the concepts Drexler proposed concerning nanorobotics computation and artificial intelligence through an interesting and insightful science fiction novel. Crichton delves in to the ethical implications of the unpredictability of evolutionary and machine learning programs, inability of technologists to learn from past mistakes,
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...

Rapid advancements in nanosciences and nanotechnologies in recent years have opened up new prospects for so many industrial and consumer sectors that they have been regarded as the hotbed of a new industrial revolution.
Nanotechnology is science, technology and engineering that is conducted at the nanoscale. The nanoscale is about 1 to 100 nanometres.
