Many real examples of nanotechnology do exist, but others (such as nanobots) are imaginary. Nano is very, very small. Nanobots are not real and do not currently exist. There are many challenges related to creating a nano-sized robot..
Consequently, do we have nanotech?
The trouble with the word "nanotechnology" is that it refers mostly to an idea from science fiction and futurism: nanoscopic, self-replicating machines that can turn any piece of matter into another piece of matter in seconds. These do not exist.
Secondly, can nanobots actually exist? There are no nanobots. There can never be tiny lathes that make tiny parts that get assembled into nanobots. You see the power of a machine goes down as the cube of its size, but friction only goes down as the square, and manufacturing tolerances and surface tension and viscosity don't go down much if at all.
Also, how is nanotechnology used in everyday life?
The average person already encounters nanotechnology in a range of everyday consumer products – nanoparticles of silver are used to deliver antimicrobial properties in hand washes, bandages, and socks, and zinc or titanium nanoparticles are the active UV-protective elements in modern sunscreens.
How far is nanotechnology?
about 1 to 100 nanometers

How small is nano?
Just how small is “nano?” In the International System of Units, the prefix "nano" means one-billionth, or 10-9; therefore one nanometer is one-billionth of a meter. It's difficult to imagine just how small that is, so here are some examples: A sheet of paper is about 100,000 nanometers thick.When were nanobots created?
The first scientist to mention the term “nanobots” was the physicist Richard Feyman in 1959; when he gave his popular talk named “There's Plenty of Room at the Bottom. He commented about nanodips and nanobots for curing heart diseases.How much do nanobots cost?
More than 50million surgeries will be performed in 2014 in the US, and the cost will range between $25 and $150 per minute in the operating room.Is nanotechnology safe?
“Guidances alone are not sufficient to account for the novel risks of nanotechnology. The FDA must issue mandatory regulations.” According to the Center for Food Safety, nanoparticles in food or food packaging can gain access to the human body via ingestion, inhalation or skin penetration.What is Nano intelligence?
Nanotechnology (or "nanotech") is manipulation of matter on an atomic, molecular, and supramolecular scale. Nanotechnology may be able to create many new materials and devices with a vast range of applications, such as in nanomedicine, nanoelectronics, biomaterials energy production, and consumer products.What is Nano food?
The term 'nanofood' describes food that has been cultivated, produced, processed or packaged using nanotechnology techniques or tools, or to which manufactured nanomaterials have been added.67 Nanofood has, in fact, been part of food processing for centuries, since many food structures naturally exist at the nanoscale.What are the dangers of nanotechnology?
Nanoparticles are likely to be dangerous for three main reasons: Nanoparticles may damage the lungs. We know that 'ultra fine' particles from diesel machines, power plants and incinerators can cause considerable damage to human lungs.What is Nano poisoning?
Nanotoxicology is the study of the toxicity of nanomaterials. Because of quantum size effects and large surface area to volume ratio, nanomaterials have unique properties compared with their larger counterparts that affect their toxicity.Will nanotechnology improve our way of life?
Some researchers expect nanotechnology to transform our lives just as much, within the next decade or so. But researchers are working to develop nanotechnologies that could revolutionize life all over the globe, by fighting disease, generating clean energy, improving food supplies, and purifying water.Why is nanotechnology important?
