Engineered TiO 2 nanoparticles are also used in light-emitting diodes and solar cells. [6]: 82 In addition, the photocatalytic activity of TiO 2 can be used to decompose organic compounds in wastewater. [4] TiO 2 nanoparticle products are sometimes coated with silica or alumina, or doped with another metal for specific applications. [6]: 2 [10]
Titanium dioxide, also known as titanium(IV) oxide or titania / t aɪ ˈ t eɪ n i ə /, is the inorganic compound derived from titanium with the chemical formula TiO 2.When used as a pigment, it is called titanium white, Pigment White 6 (PW6), or CI 77891. [4]
Webster's research has examined the multiple uses of nanotechnology. His studies focus on the development, production, and assessment of nanophase materials as superior biomedical materials . [ 4 ] He has conducted in-depth research on the application of nanophase materials for tissue regeneration .
Nanotechnology-on-a-chip is one more dimension of lab-on-a-chip technology. Magnetic nanoparticles, bound to a suitable antibody, are used to label specific molecules, structures or microorganisms. Silica nanoparticles, in particular, are inert from a photophysical perspective and can accumulate a large number of dye(s) within their shells. [42]
Inorganic nanoparticles have been largely adopted to biological and medical applications ranging from imaging and diagnoses to drug delivery. [22] Inorganic nanoparticles are usually composed of inert metals such as gold and titanium that form nanospheres, however, iron oxide nanoparticles have also become an option.
The metal-based nanoparticles used for biomedical prospectives are extremely enticing in various applications due to their distinctive physicochemical characteristics, allowing them to influence cellular processes at the biological level. The fact that metal-based nanoparticles have high surface-to-volume ratios makes them reactive or catalytic.
An example of this has occurred in the US, and involves nanoparticles of titanium dioxide (TiO 2) for use in sunscreen where they create a clearer cosmetic appearance. In this case, the US Food and Drug Administration (FDA) reviewed the immediate health effects of exposure to nanoparticles of TiO 2 for consumers.
The International Journal of Nanomedicine is a peer-reviewed medical journal covering research on the application of nanotechnology in diagnostics, therapeutics, and drug delivery systems throughout the biomedical field. The journal was established in 2006 and is published by Dove Medical Press.
