Abstract:
Quantum dots (QDs) with a nanoscale size range have attracted significant attention in various areas of nanotechnology due to their unique properties. Different strategies for the synthesis of QD nanoparticles are reported in which various factors, such as size, impurities, shape, and crystallinity, affect the QDs fundamental properties. Consequently, to obtain QDs with appropriate physical properties, it is required to select a synthesis method which allows enough control over the surface chemistry of QDs through fine-tuning of the synthesis parameters. Moreover, QDs nanocrystals are recently used in multidisciplinary research integrated with biological interfaces. The state-of-the-art methods for synthesizing QDs and bioconjugation strategies to provide insight into various applications of these nanomaterials are discussed herein.
摘要:
具有纳米级尺寸范围的量子点(QD)由于其独特的性质而在纳米技术的各个领域引起了极大的关注。据报道,量子点纳米粒子合成的不同策略,其中各种因素,比如尺寸,杂质,形状,和结晶度,影响量子点的基本性质。因此,为了获得具有适当物理性质的QD,需要选择一种合成方法,其允许通过精细调节合成参数来充分控制QD的表面化学。此外,量子点纳米晶体最近被用于与生物界面集成的多学科研究。本文讨论了用于合成QD和生物缀合策略以提供对这些纳米材料的各种应用的洞察的现有技术方法。
