Abstract:

Compared with the conventional organic fluorescent dye, quantum dots (QDs) is a new fluorescence material and has the advantages of abundant color, stable photochemical properties, little fluorescence scattering and photobleaching, and low biological toxicity. Consequently, it is widely applied in the fields of  biological tag, human pathology,material science,plant cell detachment and mark,genomics,proteomics,microorganism, biological imaging,biochip and so on. We reviewed the characteristics and research progress of QDs,and its  application in animal,plant and medicine. Meanwhile, we analyzed its essentiality, feasibility and application value in plant research. We also prospected the QDs application in plant, and the detailed research direction.

Key words: quantum dots, probe, plant

摘要：

量子点是一种最新型的荧光材料,与传统的有机染料分子相比,具有颜色丰富、光化学性质稳定、荧光散射少、光漂白作用小、生物毒性低等特点。量子点在生物标记、人体病理学、材料科学、植物细胞分离与标记、基因组学、蛋白质组学、微生物、生物成像以及生物芯片等研究领域中都具重要作用。综述了量子点的特征、研究进展以及在动植物、医学中的应用,分析了它在植物研究上的必要性、可行性和应用价值,并对量子点在植物中的应用前景和具体研究方向进行了展望。
