Circularly Polarized Luminescent Quantum Dots Prepared in Chiral Nanospace of Proteins

在本研究中，我们以空心蛋白铁蛋白作为生物矿化模板制备了圆偏振发光CdS量子点。此外，我们还阐明了从蛋白质到量子点的手性转移机制。结果表明，在室温下，我们成功地制备了圆偏振发光CdS量子点，铁蛋白内核的手性被有效地转移到CdS量子点的晶格结构上。此外，我们还可以利用激光制造技术成功地调制圆偏振发光的发射波长。

In this study, we prepared circularly polarized luminescent CdS quantum dot by using hollow protein, ferritin, as a template for bio-mineralization. In addition, we elucidated mechanism of the chiral transfer from protein to quantum dots. As a result, we successfully prepared circularly polarized luminescent CdS quantum dots by using ferritin as a template at room temperature, in which chirality of the inner core of ferritin was efficiently transferred to the lattice structures of the CdS quantum dots. In addition, we could succeed in modulation of emission wavelength of the circularly polarized luminescence with laser fabrication technique.
