量子点是一种新型的荧光材料,由于独特的微观结构和物理、化学特性,使其在生物医学领域有广阔的应用前景.通过对近十多年来,有关含重金属的量子点制备技术、应用实例等的现状分析,提出了合成新颖的无重金属量子点即低毒性或生物兼容性量子点的重要意义和迫切性,介绍了合成低毒性或生物兼容性量子点的最新研究现状,并展望了今后的发展前景.
Quantum dots(QDs), with unique microstructure and physical chemistry properties, is a kind of new fluorescent materials. It has extensive application future in biomedical field. Through analysing synthesis technologies and applied examples of heavy-metal QDs, the key implication and urgency of non heavy-metal QDs, lowly toxic and highly biocompatiable quantum dots, are proposed. The recent progresses in synthesis and future development perspectives of non heavy-metal QDs are also presented.
