제목 Rapid and facile synthesis of (ZnxAgyInz)S2 nanocrystal library  through sono-combichem method and bio application  
초록 Unlike general QDs, the (ZnxAgyInz)S2 nanocrystals could be controlled in a wide range of visible light by change the compositional elements. We have developed a facile and rapid synthesis of highly fluorescent nanocrystal (NC) library, based on ultrasonic and combinatorial chemistry. Among total 66 NCs, many NCs are highly fluorescent upon UV irradiation, and are categorized into blue, green, yellow, orange, and red by their distinct emission wavelength ranges. The NCs not only have long fluorescence lifetime, but also comparable or even higher brightness than QD without photoblinking in single NC analysis. Their unique photophysical properties together with less-toxic nature can permit the tZAIS system to be practically utilized in various bioimaging fields, especially single nanoparticle-based imaging and tracking.
