Outline of Final Research Achievements |
Luminescent semi-conductive nano-spheres as CdSe and CdTe can be widely applied to various industrious devices such as molecular carrier, memory device, photo-conductive material, photo-cells and so on. Its usage are varied. Therefore, it is being expected to develop the simple and easy synthetic method of quantum dot nanoparticles, which can be avoided the conventional method. In this study, we have attempted to develop the new method based on bioprocess with microbes capable of reducing Se- or Te-oxyanions, to synthesize II-VI group semi-conductive contained Se or Te. We have found and confirmed by the TEM observation and the EDS analysis, that new marine isolate, Shewanella sp strain KND-1, could synthesize amorphous nano-depositions that contained Se and metal such as Pb, Co and Ni by incubating the cells under selenate and heavy metal anion co-existing condition. These results suggested that our isolate is available for the synthesis of Se and metal contained fine particles.
