| 摘要 |
The present invention provides fluorescent nanoparticle composites themselves, the process of preparing such composites, to systems for rapid diagnosis (as kits) containing such composites, and to the use of such composites. In a preferential embodiment, the composites of the present invention have an affinity for biological molecules, such as DNA. The present invention also comprises the preparation of probes containing biological material, upon which are added fluorescent nanoparticle composites, making viable a rapid and economic biological diagnosis of, for example, diseases and genetic traits, notably in the medical and veterinarian fields. There is yet the fact that the absorption of radiation in the ultraviolet and visible regions, with the emission of light in the near ultraviolet and visible range, including in the colors of deep blue and/or green, provides advantageous use of its fluorescent properties in photovoltaic or electroluminescent devices, such as organic LEDs, or for the increase in luminous gain of fluorescent lamps, which represents another characteristic of the invention.
