an overview of the recent research on the fundamental and applied properties of nanoparticles extracted from cellulose‚ the most abundant polymer on the planet and an essential renewable resource. Given the rapid advancements in the field and the high level of interest within the scientific and industrial communities‚ pioneered the use of cellulose nanoparticles (cellulose nanocrystals or whiskers and cellulose microfibrils) in nanocomposite applications. in the life sciences and bio-based applications

About Nanotechnology Email | Print Imagine being able to observe the motion of a red blood cell as it moves through your vein‚ or being able to watch as a type of white blood cell (called a "T-cell") destroys an invading microbe by engulfing it. What would it be like to observe the vibration of molecules as the temperature rises in a pan of water? To observe sodium and chlorine atoms as they get close enough to actually transfer electrons and form a salt crystal? New scientific tools‚ developed

Many solid materials are at some point powder or granular in form e.g. foods (grain‚ flour‚ sugar)‚ ceramics and building materials (sand and cement). In pharmaceutical development and manufacture‚ particle size greatly influences physical properties such as powder flow‚ powder mixing‚ drug dissolution‚ deposition from inhaler devices and the stability

Vaccines represent one of the great achievements in public health. A turning point in the war against pathogenic infection occurred over 200 years ago when Edward Jenner used cowpox to elicit protective immune responses against a devastating outbreak of smallpox. Since then‚ the use of safe and effective vaccines to prevent infection has become a fundamental aspect of modern medicine. While many vaccination campaigns have been successful‚ the constant emergence‚ and re-emergence‚ of pathogens challenges

If we are using nanoscience in everyday life in future ‚ then it could affect the environment very much ‚ so we don’t have that much advanced facilities to stop nanoparticles from going through them .Nanotechnology can make our life luxurious ‚ but we may even lose an identity

Safety of Sunscreen The sun’s rays have powered life on our planet since its creation‚ and have made life possible for all living things. The sun is one of the most important elements of the universe‚ but in recent years has only been condemned for some of its harmful effects on humans. Lately‚ all that is heard about the sun anymore is how can be harmful and how protection from overexposure is needed. Many people are scared of dangerous overexposure effects such as sunburn‚ premature aging of the

NANOTECHNOLOGY AND SOME USAGE AREAS OF IT The nanometer is a unit length which equals 10-9 meters‚ in other words‚ billionth of a meter. In basic‚ logical perspective‚ the definition: the science‚ which studies the matter in nano dimensions for the term “nanoscience” is quite perceptible. However‚ to deeper understanding‚ it is useful to take a look at a wide definition of the nanotechnolocy‚ provided by U.S. National Nanotechnology Initiative. According to the initiative‚ “Nanotechnology is the
