Purpose of the development: Ukrainian Institute founded and is engaged in research of new nano-dispersed materials - luminescent nanocrystals and nanostructured composite materials with the desired properties, for various technical and medical applications.

Recommended application field: Inorganic nanocrystals have proven themselves as effective materials for fluorescent, display and laser technology. In addition, based on their create different sensors. But one of the most promising applications of these nanocrystals is used in medicine. They can be used as potential markers and fluorescent probes in living cells. Scientists have also recently discovered that some nanoparticles can affect the metabolism in the living cell.

Advantages over analogues: The transition from bulk to nanodispernym luminescent material allows you to vary the optical capabilities in a wide range. In addition, the Ukrainian scientists have conducted a series of experiments for the first time proved that the antioxidant properties of CeO2 nanocrystals can be controlled by optical spectroscopy methods. This opens the possibility of studying the dynamics of the processes of neutralization of the active oxygen of CeO2 nanocrystals - in model systems and in vitro, with the introduction of nanoparticles in the culture of living cells.

The development stage readiness: tested in laboratory condition

Description of the development:
()
Scientists unique antioxidant properties of nanocrystals of ceria were found, which can restore their properties in a biological environment, due to the constant change in the valence of the cerium ions with 3 to 4 or vice versa. This differs significantly from the chemical CeO2 nanocrystals antioxidants: unlike other nanoparticles used solely as a passive nanocontainers for drug delivery into living cells nanocrystals CeO2, constantly regeneruyuchis themselves can affect the oxidation processes at the cellular level. Also, researchers have for several years been developing luminescent composite materials based on nanoporous xerogel SiO2. They are synthesized by the sol-gel method, so they are also called the sol-gel matrices. These matrices are easy to manufacture, are chemically stable, does not require further machining, have a wide range of transparency. Moreover, the size and shape of the final product can be varied quite easily. The high porosity of the sol-gel matrix allows you to enter them in the various supplements - phosphors, dyes, inorganic quantum dots and organic scintillators. This created a number of new composite luminescent and scintillation materials for engineering.
