Nanotechnology
Nanotechnology is a Field of Research and Innovation:
Generally, Materials and Devices - on the Scale of Atoms and Molecules. A Nanometre is one billionth of a metre ten times the Diameter of a Hydrogen atom. The Diameter of a Human hair is, on average, 80,000 Nanometres.
What is Nanotechnology used for:
Nanotechnology is being used in to treat Disease and Prevent Health Issues. Nanotechnology is also being applied to or developed for application to a variety of industrial and Purification processes.
What Exactly is Nanotechnology:
Nanotechnology is defined as the Study and use of Structures between 1 Nanometer and 100 Nanometers in size. To give you an idea of how small that is, it would take eight hundred 100 Nanometer Particles side by side to match the width of a Human Hair.
What Technologies use Nanotechnology:
Nanotechnology Applications, Electronics, Chemical Sensors, Nanomedicine, Medicine, Chemotherapy, Radiation Therapy, Heat Therapy, Heart Disease, Drug Delivery, Diagnostic Techniques, Diabetes, Kidney Disease, Wound Treatment, Antibacterial Treatments, Life Extension, Education.
What products use Nanotechnology:
Everyday products that use Nanotechnology Sunscreen. NanoParticles have been added to Sunscreens for years to make them more effective. Clothing, Furniture, Adhesives, Coatings for car paintwork, Tennis balls, Computers.
Is Nanotechnology Harmful:
Passage of inhaled NanoParticles into the Bloodstream. Materials which by themselves are not Harmful could be Toxic if they are inhaled in the form of NanoParticles. The effects of inhaled NanoParticles in the Body may include lung inflammation and Heart problems.
Why is Nanotechnology so important:
Nanotechnology improves industrial Processes, Materials and applications by Scaling them down to the Nanoscale in order to ultimately fully exploit and Surface Phenomena that matter exhibits at the Nanoscale.
How is Nanotechnology Used in Everyday Life:
Nanotechnology has an influence on all Sectors of Food and Agricultural Systems, such as food Security, Disease Treatment Delivery Methods, new Tools for Molecular and Cellular Biology, new Materials for Pathogen detection, and Protection of the Environment.
How can Nanotechnology improve our Lives:
Nanotechnology might help us make Electrical Lines, Solar Cells, and Biofuels more efficient, and make Nuclear Reactors Safer. Nanotechnology to Huge advances in Health care, improving methods for Detecting and Treating Diseases like Cancer.
What Foods have Nanotechnology:
Nanotechnology include Candies, Skittles, Baby Bottles and Plastic storage containers.
How do NanoParticles leave the Body:
NanoParticles which are not absorbed by the gut or the Lungs leave the Body in the Faeces either directly or moved up from the Lungs by Normal clearance of Mucus and then Swallowed.
Why Can NanoParticles pass through the Skin:
Those Proteins Normally act as Gatekeepers that determine which Molecules to allow through the Skin and into the Body, and which Molecules to block. When the Proteins Loosen up, they become less selective than usual, possibly giving NanoParticles an opportunity to pass through the Barrier.
Nanomaterials that are found in Nature
Naturally occurring NanoParticles can be found in volcanic Ash, Ocean Spray, Fine Sand and Dust, and even Biological matter (e.g. viruses). Synthetic NanoParticles are Equally, if not more Diverse than their Naturally Occurring Counterparts.
How Nanotechnology used in the Environment
Nanotechnology has Enormous Potential for Providing Innovative Solutions to a Wide range of Environmental Issues. These include improved methods for reducing Pollution, Water Treatment, Environmental Sensing, Remediation, and making alternative energy Sources more Cost effective.
Where are NanoParticles found in Nature
NanoParticles are ubiquitous in the environment. They may originate from natural and anthropogenic sources. Natural NanoParticles are those that are produced in Nature, and they include ocean spray, forest fire, dust storms, volcanic Ash and biological Particles such as bacteria and fungi.
Do Nanomaterials exist in Nature
Naturally occurring Nanomaterials can be found everywhere in Nature (fullerenes and Graphene even have been Discovered in Space) and only with recent advances in instrumentation and Metrology equipment are researchers beginning to Locate, Isolate, Characterize.
How can we see NanoParticles
Microscopy methods generate images of individual NanoParticles to characterize their Shape, Size, and Location. Electron Microscopy and Scanning Probe Microscopy are the Dominant methods. Because NanoParticles have a size below the diffraction limit of Visible Light, Conventional Optical Microscopy is not useful.
What are the examples of Nanotechnology:
A few examples of current Nanotechnology include the following.
Food security. Nanosensors in packaging can detect salmonella and other contaminants in food. Medicine. Energy. Automotive. Environment. Electronics. Textiles. Cosmetics.
How is Nanotechnology used in everyday life:
Nanotechnology is a new and expanding technology, its main applications are the development of innovative methods to fabricate new products, to formulate new chemicals and materials, and to substitute the current generation of equipment with improved performance equipment, resulting in a lower consumption of materials.
Nanotechnology safe for humans:
Out of three human studies, only one showed a passage of inhaled Nanoparticles into the bloodstream. Materials which by themselves are not very harmful could be toxic if they are inhaled in the form of Nanoparticles. The effects of inhaled Nanoparticles in the body may include lung inflammation and heart problems.
What diseases can Nanotechnology cure:
Nanomedicine — the application of Nanomaterials and devices for addressing medical problems — has demonstrated great potential for enabling improved diagnosis, treatment, and monitoring of many serious illnesses, including cancer, cardiovascular and neurological disorders, HIV/AIDS, and diabetes, as well as many types.
Can Nanotechnology cure aging:
The “killer app” of Nanotechnology is “Nanobots,” which are blood-cell sized robots that can travel in the blood stream destroying pathogens, removing debris, correcting DNA errors, and reversing aging processes.
Can Nanotechnology extend human life:
There are two ways in which Nanotechnology may be able to extend our lives. One is by helping to eradicate life-threatening diseases such as cancer, and the other is by repairing damage to our bodies at the cellular level, a Nano version of the fountain of youth.
What is so special about Nanotechnology:
Nanotechnology is not simply working at ever smaller dimensions; rather, working at the Nanoscale enables scientists to utilize the unique physical, chemical, mechanical, and optical properties of materials that naturally occur at that scale.
