But Sun blocks containing Nano particles of Titanium Dioxide, which are evenly spread and thinner, do not scatter light rays, and provide much transparent coating enabling the skin color to appear. Cloths produced incorporating nanotechnology and containing tiny Nano fibers do not retain dust or dirt because the holes of the cloth are tinier than the dust particles. These beneficial changes in the characteristics of the physical matter manipulated at the nano scale can be used in many areas such as medicine, sport, chemical industry etc.
The concept of “Nanotechnology” was first introduced by a physicist, Richard Feynman in his speech “Theres Plenty of Room at the Bottom” delivered at a meeting of the American Physical Society in 1959 (Toumey, 16-23 & Taniguchi). In his speech he explained taking a human cell as an example for naturally existing highly effective, multi purpose nano scale machine and emphasized the usefulness of such small scale equipments.
There are two approaches in the direction of handling materials and making products or equipments using Nanotechnology. The more conventional approach “Larger to smaller” or “Top to bottom” handling starts with larger physical materials and then shaped up or arranged to much smaller final product such as Nano particles of Titanium Dioxide, Nano fibers etc.
The other approach “smaller to larger” or “bottom to top” starts with simple smaller molecules or atoms and then build up or assemble until the final expected product is achieved. The second approach, atomic assembly has many limitations and comparatively difficult than the first method because of the limitations in human ability to sense and handle materials of very small scale. Therefore sophisticated equipments are needed for the manipulation of these materials.

...Initiative, much financial resources are being diverted towards advancing nanotechnology. Nanotechnology may sometimes be referred to as a general purpose technology. This is because in an advances form of the technology, it will show significant impact on most of the industries as well as all the areas of the society. Nanotechnology will offer cleaner, better built, safer, longer lasting, and smarter products for communications, for homes, for transportation, for medicine, for agriculture, and for industry as a whole (Roberts 16). Nanotechnology will also offer an improved efficiency in all facets of life. As a technology of general purpose, it will be of dual...

Nanotechnology accessed all the time. With these micro chip, database of an encyclopedia or stories from books can be saved and read without the necessity of purchasing those bulky materials. The host devices of these microchips allow its capacity and functionalities to be optimized at the maximum level. Indeed, technology has taken over our very lives that going to school becomes impossible without computer or laptop that can be used for written assignment and to inter connect to online information to access for database for knowledge development. The world can be studied now in a touch and anybody can navigate across regions to study its geophysical state. References ACTU (2009)....

...? Na chnology: Top Down and Bottom Up To Na chnology of Na chnology: Top Down and Bottom Up To Nanotechnology As per the advancement in the field of nanotechnology, it has been ensured that couple of approaches can be used to create the nano designs of the machines. These approaches are mainly referred to as Top down and Bottom up approach in nanotechnology. With the implication of bottom up approach, it is possible to design a microchip with its tiniest size manufacture. It is possible because the smallest atoms are placed in such a matter that the design goes to the upper version of approach. On the other hand, the top-down approach of manufacture in...

...into miniatures version of their would be normal size. It also contributes towards solving conversion of current existing drugs into drugs that can easily be utilized by the body. This is following properties of drugs in that they are insoluble in water. Nanotechnology does this by reducing the size of the particles into the nanometer range; thus, increasing the surface area of the drug for improved absorption. In addition, nanotechnology in medicine is crucial in improving solubility due to the presence of nano-sized receptors present in the surface of cells. This means that nanotechnology helps greatly in absorption and interaction with biomolecules (Martis et al...

The entry of man-made nanoparticles in daily products is developing concerns that overexposure to any forms of nanotechnology may result in toxicity and disease. Nanotechnologies can be possibly harmful and NIOSH gave an extensive list of standards and precautions related to such, it is vital to note that research is ongoing and researchers are continuing to monitor and evaluate risks to workers and the public alike (Langwith 143). According to the National Centre for the Replacement, Refinement, and Reduction of Animals in Research...

...Introduction Atomic force microscopy, the optical tweezers, alongside other na chnology tools has made it possible to induce and monitor large conformational changes in biomolecules (Salam 45). These studies are often been performed in helping asses the biomolecules structure, their elastic properties, as well as their ability to work as nanomachines in cells. Stretching studies on protein have increasingly become of particular interest and they have been done in systems more than a hundred. All-atom or coarse-grained simulation [], such as those reported in refs, has helped the interpretation of such experiments possible. However, they have been limited by order 100 ns time scales. They, thus, need the use of large...

Nanotechnology works by making use of the nano materials that have antimicrobial properties and makes use of encapsulated benzoyl oxide, which improves the activity as well as the tolerability of the anti-acne agent. Acne comes into the picture as being one of the most common dermatological conditions. Nanotech medication that has strong antimicrobial properties to treat an infectious disease can be devised. The drugs will be administered and allowed to diffuse in the target body fluid with some pressure being felt; the upward and downward...
