Nano-bioengineering of enzymes is aiming to enable conversion of cellulose from wood chips, corn stalks, unfertilized perennial grasses, etc. Cellulosic nanomaterials have demonstrated potential applications in a wide array of industrial sectors, including electronics, construction, packaging, food, energy, health care, automotive, and defense.
Cellulosic nanomaterials are projected to be less expensive than many other nanomaterials and, among other characteristics, tout an impressive strength-to-weight ratio. Nanostructured ceramic coatings exhibit much greater toughness than conventional wear-resistant coatings for machine parts. Nanotechnology-enabled lubricants and engine oils also significantly reduce wear and tear, which can significantly extend the lifetimes of moving parts in everything from power tools to industrial machinery.
Nanoparticles are used increasingly in catalysis to boost chemical reactions. This reduces the quantity of catalytic materials necessary to produce desired results, saving money and reducing pollutants. Two big applications are in petroleum refining and in automotive catalytic converters. Nano-engineered materials make superior household products such as degreasers and stain removers; environmental sensors, air purifiers, and filters; antibacterial cleansers; and specialized paints and sealing products, such a self-cleaning house paints that resist dirt and marks.
Nanoscale materials are also being incorporated into a variety of personal care products to improve performance. Nanoscale titanium dioxide and zinc oxide have been used for years in sunscreen to provide protection from the sun while appearing invisible on the skin. Electronics and IT Applications Nanotechnology has greatly contributed to major advances in computing and electronics, leading to faster, smaller, and more portable systems that can manage and store larger and larger amounts of information.
At the moment, nanotechnology is unregulated. Companies even do not have to label the products, which contain nanoparticles. In fact, there are no recognized standards for producing and handling nanomaterials. Many people are suspicious about the potential effects of nanomaterials on our health, planet, and ecosystems. Some studies claim that certain kinds of nanomaterials are quite toxic to algae, invertebrates, and fish. Nanomaterials can be even transferred across many generations in animals and plants.
We have to stay informed about this new technology. People should share what they know with others. The more people know about nanotechnology, the more likely that manufacturers will take into consideration health and safety standards. Modern computers have longer-lasting batteries. Circuits, which are made from carbon nanotubes, aim to maintain computer power. Most nanomaterials, as the NCI suggests, will likely prove to be harmless. But when a technology advances rapidly, knowledge and communication about its safety needs to keep pace in order for it to benefit, especially if it is also to secure public confidence.
We only have to look at what happened, and to some extent is still happening, with genetically modified food to see how that can go badly wrong. Forehead thermometers provide a quick and hygienic way to take a person's temperature. Learn more about how accurate they are here.

Nanotechnology makes it possible to develop smart fabrics that don't stain nor wrinkle, as well as stronger, lighter and more durable materials to make motorcycle helmets or sports equipment.
There are bright and dark spots in the future of nanotechnology. On the one hand, the sector is expected to grow globally, driven by technological advances, increased government support, increased private investment and growing demand for smaller devices, to name a few. However, the environmental, health and safety risks of nanotechnology and concerns related to its commercialisation could hamper market expansion.
