nanotechnology
Nanotechnology (sometimes shortened to "nanotech") is the manipulation of matter on an atomic and molecular scale. The earliest, widespread description of nanotechnology[1][2] referred to the particular technological goal of precisely manipulating atoms and molecules for fabrication of macroscale products, also now referred to as molecular nanotechnology. A more generalized description of nanotechnology was subsequently established by the National Nanotechnology Initiative, which defines nanotechnology as the manipulation of matter with at least one dimension sized from 1 to 100 nanometers. This definition reflects the fact that quantum mechanical effects are important at this quantum-realm scale, and so the definition shifted from a particular technological goal to a research category inclusive of all types of research and technologies that deal with the special properties of matter that occur below the given size threshold. It is therefore common to see the plural form "nanotechnologies" as well as "nanoscale technologies" to refer to the broad range of research and applications whose common trait is size. Because of the variety of potential applications (including industrial and military), governments have invested billions of dollars in nanotechnology research. Through its National Nanotechnology Initiative, the USA has invested 3.7 billion dollars. The European Union has invested 1.2 billion and Japan 750 million dollars.[3]

While there have been many advancements in this field, so far, the main problem [...]
The veined wing of the clanger cicada kills bacteria is able to destroy bacteria by its structure alone – one of the first structures ever found that can do this. The clanger cicada is an insects that looks like something between a fly and a locust; its wings are covered with a vast hexagonal array [...]
Most of the time, when you’re sick, you want to deliver drugs and imaging agents to diseased cells or tumours where they’re needed most – that’s a problem researchers have solved quite a while ago, we can get particles pretty much wherever we want to. The thing is, most of the time, these agents are [...]
Finding ways to diagnose cancer earlier could potentially save millions of lives, improving the chances of survival for many patients. This is why researchers have developed nanoparticles which amplify tumor signals, making them much easier to detect. Nanotech to the rescue The new technology was developed by researchers from MIT and it makes biomarker detection [...]
While on the macro-scale conventional scales make us of gravity to measure mass, on the microscale there are a myriad of factors that interfere with measurements. Scientists at Universitat Autònoma de Barcelona have successfully created a scale made out of a single carbon nanotube which can accurately measure the smallest unit of mass, a yoctogram (one [...]
In what can only be hailed as a breakthrough in the “smart drugs” field, scientists at Harvard University have successfully managed to create nanorobots made out of strands of DNA, folded together by the DNA origami method. These act like drug-carrying recipients, which specifically target various types of cells and deliver complex molecular instructions – [...]
By harnessing the science of both quantum and nano physics, scientists at the Niels Bohr Institute have come up with an innovative new way of cooling semiconductor membranes by using laser light. Through this new technique, the researchers were able to cool the tiny, thin membrane from room temperature to -269 degrees Celsius. Paradoxically, the [...]
Remember this name: graphene. This wonder material is certainly on a lot of scientists’ lips these days, but in a few years from now, it will be on the lips of more and more people, as its fantastic properties will begin to be put to practical use. Graphene is a planar sheet of Carbon, just [...]
At the nano scale, even the slightest of motions can be harnessed and transformed into useful work. Material science researchers at the University of Wisconsin, for instance, have developed a very thin plastic belt capable of vibrating from low velocity fluid flow, such as one’s breath. Made out of polyvinylidene fluoride (PVDF), the microbelt not only [...]
Scientists at Northwestern University have developed a new nanomaterial of exciting properties, which will allow for the computer of the future to rewrite and rewire its circuitry, and in the process become an entirely different device. Thus, a single device could rewire itself to become resistor, a rectifier, a diode or a transistor simply based on signals. [...]
You’ve seen James Bond’s vanishing Aston Martin or Frodo’s Elven cloak, and probably always wished for your own means of becoming totally invisible. The are a lot of perks to such a technology (who here remembers Invisible Man movies?), and scientists from University of Dallas in Texas have managed to devise an invisibility cloak inspired by [...]
DNA nanotechnology is one of the most exciting branches of nanotechnologies, especially because it uses the ability of natural DNA strains to self assembly. Prof. Alexander Heckel and his doctoral student Thorsten Schmidt of Goethe University set out with exactly that thought in mind when they created two DNA rings with the size of only [...]
I had no idea IBM was doing this kind of thing too, but I recently found out that they developed a technology that could revolutionize the treatment of drug resistant bacteria. A whole team of engineers and researchers headed by Dr. James Hedrick at IBM Inc. has worked on this technology, which relies on a [...]
Batteries ? Ha, no way, batteries are so last century. Nanogenerators, that’s the future. At least that’s what Apple believes. Nanogenerators powered by nothing more than your heartbeat could replace the classic battery in no more than five years, according to researchers working on the matter. In a world ruled by 4G smartphones, touchscreens, portable [...]
In a paper presented at the International Solid-State Circuits Conference (ISSCC) in San Francisco, researchers from Michigan University unveiled one of the most exiting electronic-based prototype I’ve been grated to see in a very long time. Pictured above is an implantable eye pressure monitor which can be used to watch for signs of glaucoma in [...]
Hello! I’ve been running ZME Science for more than 2 years now, and the support you’ve shown has been increasingly amazing! However, much to my shame, I’ve rarely thanked you like you deserve it. I rarely have time to write as much as I want, I make grammar mistakes (non English speaker, btw), and I [...]
Nanotechnology is perhaps the field with the most spectacular development over the past years, but it can be really hard to understand what’s going on at that scale, mostly because we can’t see it (doh!), but also because the laws that apply there are slightly different. No small matter: Science on the nanoscale is the [...]
Raymond Kurzweil is one of the most prolific inventors and futurists; he’s the one who developed text to speech synthesis and a synthesizer that develops and even creates poetry, among others. He has also predicted new technologies that would appear and some directions that our society would take, and he got it right. Now, the [...]
Meet the world’s tiniest portraits of an elected president ever; meet the nanobamas. Each ‘Obama’ is made up of about 150 million tiny carbon nanotubes, which is about how many Americans voted in this year’s presidential election. An assistant professor professor in the Department of Mechanical Engineering at the University of Michigan, John Hart, along [...]
Researchers at at the U.S. Department of Energy’s Brookhaven National Laboratory have achieved something that many people call the Holy Grail of Nanoscience; this in fact reffers to the fact that they have used for the first time DNA to guide the creation of three-dimensional, ordered, crystalline structures of nanoparticles (particles with dimensions measured in [...]
There are already numerous ways of storing gas but this is in fact a new concept, very different from those existing today and it’s not an improvement, but rather a novel method. A team of University of Calgary researchers developed this process of catching gas from the environment and holding it indefinitely in molecular-sized which [...]
Nanotech could be applied in just about everything. With time scientists find out ways to apply it to various fields; building small, efficient electronics could be very useful in further use of nanotechnology. A University of Arkansas physicist and her colleagues have examined the response of the nanostructures polarization to electric fields which is known [...]
Nanotech is a very young science. It reffers to a field of applied science and technology whose unifying theme is the control of matter on the atomic and molecular scale, normally 1 to 100 nanometers, and the fabrication of devices within that size range. A meter is 1 000 000 000 times bigger than a [...]
