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]
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.
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]
Photoactive pigments such as TiO 2 and ZnO have been used on glass, ceramic, and steel substrates for self-cleaning and antimicrobial purposes. For photocatalytic bactericidal activity in water treatment applications, granular substrate materials have been used in the form of sands supporting mixed anatase / rutile TiO 2 coatings. [ 40 ]
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.
Nanoparticles have different analytical requirements than conventional chemicals, for which chemical composition and concentration are sufficient metrics. Nanoparticles have other physical properties that must be measured for a complete description, such as size, shape, surface properties, crystallinity, and dispersion state. Additionally ...
For example, nanobiotechnologies may have hard to control effects on the environment or ecosystems and human health. 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 ...
While advancement of research proves that targeting and distribution can be augmented by nanoparticles, the dangers of nanotoxicity become an important next step in further understanding of their medical uses. [25] The toxicity of nanoparticles varies, depending on size, shape, and material. These factors also affect the build-up and organ ...
