Naturally Occurring Nanoparticles - The Hidden Dimension

Nanoparticles have fascinated great consideration owing to the increasing manufacturing and manipulation on materials by humankind. Therefore, the term "nanoparticles" usually applies only to engineered particles but not particles under 100 nm that occur naturally or are by-products of other processes such as welding fumes, fire smoke or carbon black. The term metal nanoparticle is used to described nanosized metals with dimensions (length, width or thickness) within the size range 1‐100 nm.

Platonic Nanotech Pvt. Ltd manufacture and put on the market different type of nanoparticles such as gold, silver, copper, nickel, iron, aluminum, zinc, tin, titanium oxide, cadmium oxide and gadolinium oxide, and make them accessible at realistic outlay for Research Institute and Universities. These metal nanopaticles have also received extensive concentration and have a extensive range of applications. The most widely used nanopaticulate zero-valent metals include Silver, Iron and Gold. Nanosilver has been incorporated into the greatest number of consumer product applications due to its excellent antimicrobial and antiviral activities. Nanoscale iron is most widely used in environment remediation of waters, sediments, and soil. Nanogold has been used in medical applications as vectors in tumor therapy.

Nickel nanoparticles are used as magnetic recording medium, electrical conductive pastes, battery materials, etc. Titanium oxide and zinc oxide are widely used for their photo-catalytic properties in industrial applications such as solar cells, paints and coatings. They are also finding wide applications in sunscreens and cosmetics due to excellent UV-blocking capability and visible transparency at nanoscale. Magnetic nanoparticles (with inorganic shells) – have been studied for biological application such as for binding BSA, for drug delivery, for bio‐sensing, and for bio‐separations. Metal nanoparticles (mostly supported) on the electrode can decrease the over-potentials of many electrochemical reactions and turn into reversible some redox reactions that are normally irreversible in conventional unmodified electrodes. Planar arrays of uniform metal nanoparticles would allow the design of new ˝supercomputers˝ having a superior data storage capacity.
