Nano science and nano technology comparison
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.
It is also enabling reduced fuel consumption in vehicles and power plants through higher-efficiency combustion and decreased friction. Gene sequencing can be more useful with the help of nanodevices.

Many everyday commercial products are currently on the market and in daily use that rely on nanoscale materials and processes: Nanoscale additives to or surface treatments of fabrics can provide lightweight ballistic energy deflection in personal body armor, or can help them resist wrinkling, staining, and bacterial growth.
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.
Types of nanotechnology
Nanoscale sensors and devices may provide cost-effective continuous monitoring of the structural integrity and performance of bridges, tunnels, rails, parking structures, and pavements over time. But something as small as an atom is impossible to see with the naked eye. Nano-coatings of metallic surfaces on vehicles is being fabricated for increased hardness, low friction, and improved corrosion protection. For instance, novel materials can be engineered to mimic the crystal mineral structure of human bone or used as a restorative resin for dental applications. Yes No I need help 5 Gold, an opaque and inert yellow solid at the micro scale becomes red in color at the nanoscale at room temperature. Yes No I need help Figure. The design and engineering of advanced solid-state nanopore materials could allow for the development of novel gene sequencing technologies that enable single-molecule detection at low cost and high speed with minimal sample preparation and instrumentation. Nano-engineering of aluminum, steel, asphalt, concrete and other cementitious materials, and their recycled forms offers great promise in terms of improving the performance, resiliency, and longevity of highway and transportation infrastructure components while reducing their life cycle cost. Nanotechnology can facilitate the reproduction and repair of damaged tissues. London: Sage. Nanoscience is a convergence of physics, chemistry, materials science and biology, which deals with the manipulation and characterisation of matter on length scales between the molecular and the micron-size. For example, the combination of light weight and conductivity makes them ideal for applications such as electromagnetic shielding and thermal management. Nanotechnology-enabled sensors and solutions are now able to detect and identify chemical or biological agents in the air and soil with much higher sensitivity than ever before. Courtesy of Wake Forest and the National Cancer Institute Commercial applications have adapted gold nanoparticles as probes for the detection of targeted sequences of nucleic acids, and gold nanoparticles are also being clinically investigated as potential treatments for cancer and other diseases. This has the potential to change the way doctors treat cancer and dramatically reduce the toxic effects of chemotherapy.

Nanomedicine researchers are looking at ways that nanotechnology can improve vaccines, including vaccine delivery without the use of needles.
Examples of nanoscience
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. Conventional machining tools are being replaced by nano-coated tools to slit holes in circuit boards. Yes No I need help Applications of Nanoscience and Nanotechnology The applications of nanoscience and nanotechnology in different areas are illustrated below: 1 Nanoelectronics : Nanostructured devices are being extensively fabricated for their use in the electronics industry. Nanoparticles are used increasingly in catalysis to boost chemical reactions. At the turn of the century, a typical transistor was to nanometers in size. Image courtesy of Nanosys Researchers are developing wires containing carbon nanotubes that will have much lower resistance than the high-tension wires currently used in the electric grid, thus reducing transmission power loss. Bottom-up approach has a capability to assemble the structure atom-by-atom while top-down approach deals with sub-sizing of the bulk substance to nano-level. Millions of these nano chips and nano-capacitors can be fabricated on a one square inch area. Nanoparticles are being developed to clean industrial water pollutants in ground water through chemical reactions that render the pollutants harmless.
For better or worse, these corporate labs have disappeared or been reduced to shadows of their former size, as deregulation and global competition has stripped away the monopoly rents that ultimately financed them.

Environmental Remediation In addition to the ways that nanotechnology can help improve energy efficiency see the section abovethere are also many ways that it can help detect and clean up environmental contaminants: Nanotechnology could help meet the need for affordable, clean drinking water through rapid, low-cost detection and treatment of impurities in water.
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.
