Circularly Polarized Luminescent Quantum Dots Prepared in Chiral Nanospace of Proteins

本研究以空心蛋白质铁蛋白为模板制备圆偏振发光CdS量子点，用于生物矿化。此外，我们还阐明了手性从蛋白质到量子点的转移机理。结果表明，在室温下，以铁蛋白为模板成功制备了圆偏振发光CdS量子点，铁蛋白内核的手性被有效地转移到CdS量子点的晶格结构中。此外，利用激光加工技术，我们还可以实现圆偏振发光波长的调制。

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.
