What is NanoTechnology? Have you ever wondered what this is and what it is used for? Is it tech for health? Is it tech for finance? How will it change out world? Let’s find out now! We post the most interesting and fascinating facts and videos about future technology, future tech gadgets, futuristic cties that you really should know about if you’re a fan! Thanks For Watching This Video: What is NanoTechnology?

Food additives have been around for years, the initial goal was to extend the longevity of food. Nowadays the goal has broaden and recently nanoparticles have entered this field in a way to add smaller dosages for preservation as well as nutrients.

Nanotechnology researcher Dr. George S. Tulevski is asked to explain the concept of nanotechnology to 5 different people; a child, a teen, a college student, a grad student, and an expert. Nanotechnology is the study of objects at the nanoscale (between 1 and 100 nanometers in size). Objects at this size have a peculiar set of properties that differ from objects at the macroscale. Dr. Tulevski does his best to succinctly explain this phenomenon, adapting his language and tone along the way.

I have personally experimented with three lab experiments that deal with photolithography: microfluidics, microletters, and 2-photon lithography. Microfluidics is the field of science that encompasses fluid manipulation, taking advantage of the fact that fluids act differently at a microscale. One example of this is how water acts as a non-Newtonian fluid at a microscale, meaning that unlike at the macroscale, water‚viscosity depends on the force applied to it. It would then be useful to explain how there are many biological applications for microfluidics. My experiments with micro-letters provide insight into the process with which we transcribe letters, writing, or any other patterns onto microchips using photolithography. Ben Chen is a junior at Deerfield Academy and an aspiring engineer who discovered the wonders of nanotechnology this past summer. Ben is a well-rounded person with many interests, but his core passions lie in STEM and certain sports. He hopes you’ll be able to learn something new through his talk about photolithography (one of the processes behind nanotechnology’s success), its uses in our current day and age, and its potential in our future. This talk was given at a TEDx event using the TED conference format but independently organized by a local community.

What’s the tiniest technology you can imagine? As small as a grain of rice? Or a grain of sand? Perhaps the width of an individual strand of spider web? Smaller still. Nanotechnology is so small, in fact, it is narrower than a single wavelength of visible light. To put that in perspective, it’s about the length your fingernails have grown since you started reading this overview. But when we talk about nanotechnology, we don’t mean anything with a circuit board, but the application of scientific knowledge for practical purposes. By utilising carbon nanotubes in a certain way, it’s possible to create tiny computer chips. With tiny chips come tiny computers and tiny robots. And with tiny robots – or nanobots, if you will – a whole world of possibilities opens up… 3D printers, invisibility cloaks, space elevators – you name it! Of course, with all exciting, experimental and potentially disruptive innovations come areas for concern. What impact could such technology have on our security, or the economy? How can it be regulated? Find out more in the latest video from iluli by Mike Lamb. Making sense of technology, one byte at a time.

Author Andrew Maynard reads from Films from the Future: The Technology and Morality of Sci-Fi Movies

A short introduction to nanotechnology, and why you should care about it – from author of Films from the Future and ASU professor Andrew Maynard. The video dives into materials science and advanced materials, and looks at how designing and engineering substances from the atoms they’re made of upward allows novel properties to be developed and used. It also looks at responsible innovation when it comes to grappling with the benefits as well as the health and environmental risks of nanoparticles and nanomaterials.

Nanostructured coatings and layers, only billionths of a meter thick, can be applied to an object to protect against water, dirt, wear, and even bacteria. Working at the nanoscale, scientists and engineers are developing new and innovative applications in the fields of energy, electronics, and medicine. “Nanotechnology: Super Small Science” is produced by NBC News Learn in partnership with the National Science Foundation.
