제목 Development of Quantum Dot with High Quantum Yield and Stability
초록 Luminescent semiconductor quantum dots (QDs) have many advantages including a photo-stability, a narrow emission spectrum, high quantum yield (QY) and a signal brightness, compared to a traditional fluorescent dye. For this reason, QDs are widely used to conjugate with many biological materials. However, conventional QDs have some problems in bio-application and we will discuss on one of these problems. After the surface modification of QDs for bio-applications, QY is getting significantly lower. In this study, we describe our QDs with high quantum yield. This QDs show a strong fluorescence character compared to conventional QDs. Besides, our QDs indicate a high stability in a strong pH range. After the surface modification for bio-applications, our QDs were not specifically reduced QY. In comparison with conventional QDs, our QDs were discovered a strong fluorescence as feature in vitro and in vivo.
