Why can nanotechnology umbrella has anti-bacteria effect?
Nanotechnology umbrellas are often coated with nanoparticles, like silver or titanium dioxide, which have antimicrobial properties. These nanoparticles can disrupt the cell walls of bacteria, inhibiting their growth and reproduction. This makes the umbrella surface less hospitable for bacteria to thrive on, therefore reducing the risk of bacterial contamination.
What is nanotech and their uses?
Nanotechnology is building machines on the scale of molecules, a few nanometers wide, machines so small you can barely see them with a microscope. This technology will allow us to turn coal into diamonds and diamonds into coal and dirt, water, and air into potatoes. With this we can turn atoms into remarkably light, strong, smart, and durable machines at the cost of almost a third their normal price. We could make machines with much harder molecular structures at the ease and price of simple machines.
Most of what I'm talking about right now is molecular nanotechnology, nanotechnology is the engineering of functional systems at the molecular scale. This covers both current work and concepts that are more advanced.
Disadvantages of nanotechnology in the environment?
Nanopollution is a generic name for all waste generated by nanodevices or during the nanomaterialsa manufacturing process. This kind of waste may be very dangerous because of its size. It can float in the air and might easily penetrate animal and plant cells causing unknown effects. Most human-made nanoparticles do not appear in nature, so living organisms may not have appropriate means to deal with nanowaste.
To properly assess the health hazards of engineered nanoparticles the whole life cycle of these particles needs to be evaluated, including their fabrication, storage and distribution, application and potential abuse, and disposal. The impact on humans or the environment may vary at different stages of the life cycle. Environmental assessment is justified as nanoparticles present novel (new) environmental impacts. Scrinis raises concerns about nano-pollution, and argues that it is not currently possible to "precisely predict or control the ecological impacts of the release of these nano-products into the environment."
What is the scope for nanotechnology?
there is alot of scope for this course in the future, new things keep coming up that are nano, such as memorycards, phone chips, laptop components etc etc etc...alot of things are going to come up and things in size are going to decrease and alot more...

Nanotechnology and its application in various fields?
Nanotechnology involves manipulating matter at the nanoscale, typically between 1 to 100 nanometers, allowing for the development of materials and devices with unique properties. Its applications span various fields, including medicine—where it enhances drug delivery and imaging techniques—electronics, where it improves the performance of semiconductors, and environmental science, where it aids in pollution remediation and energy efficiency. Additionally, nanotechnology is utilized in materials science to create stronger, lighter materials and in cosmetics for improved formulations. The versatility of nanotechnology holds promise for groundbreaking advancements across multiple disciplines.
What are three good uses of nanotechnology?
three main good uses of nanotechnology are ~ it may end world hunger. ~it may increase the speed of memory chips. ~it ca modify the human body.
Who discovered nanotechnology?
Nobel-prize-winning physicist Richard Feynman gave a lecture titled "There's Plenty of Room at the Bottom" on December 29, 1959 at an American Physical Society meeting at Caltech. It considered the possibility of direct manipulation of individual atoms, and is widely regarded as a milestone in the development of nanotechnology.
Practical nanotechnology started in the 1980s with the development of atomic force microscopes, which are capable of manipulating individual atoms.
K. Eric Drexler published Engines of Creation: The Coming Era of Nanotechnology in 1986, expanding on the concepts of nanotechnology, and laying out a hypothetical roadmap to achieve it.
Why is nanotechnology controversial?
Nanotechnology is controversial due to concerns about environmental and health risks, ethical issues such as potential misuse, and societal impacts like job displacement. Critics worry about the long-term effects of nanomaterials on living organisms and ecosystems, the potential for nano-scale weapons, and the disparity in distribution of benefits and risks across different populations. There is ongoing debate and discussion about how to regulate and manage the growth of nanotechnology to ensure its responsible development.
How much does Nanotechnology cost?
The simplest answer is "if you have to ask, you cannot afford it".
Currently nano-tech costs millions just to get started, plus current technology can't make the nano-tech robots do very much, so you're effectively paying a hell of a lot for little robots to do very little.
Once technology improves they will have more functionality, but the nano-tech from sci-fi stories/TV shows/films are a long way off.
How is nanotechnology useful in the field of medicine?
i need some information of nanotechnology and how it is useful in the field of medicine. then what is stem cell nanotechnology and what is the application of stem cell nanotechnology.
Who is the father of nanotechnology?
Richard Feynman fist mention the concept, though did not use the name, in 1959.
Topics related to nanotechnology?
Nanotechnology can be both be applied to health related issues and engineering. Many companies are now trying to develop this technology to help improve hospitals procedures as well as robotics.
What is the impact of nanotechnology on society?
Nanotechnology is not a product like a microchip or an automobile. It is a process that harnesses the unique properties of materials at the 1-100 nanometer scale to develop new products. Nanotechnology has the potential to profoundly impact our lives in a similar fashion as the implementation of the moving assembly line by Henry Ford in 1908. It was Ford's streamlined manufacturing process that dramatically lowered the price of production and made automobiles affordable for most Americans. These manufacturing processes were implemented across the country and helped to fuel the industrial revolution. Many feel that nanotechnology will have an impact of this magnitude.
