CdS nanoparticles have a great potential for application in chemical research, bioscience and medicine. The aim of this study was to develop an efficient and environmentally-friendly method of plant-based biosynthesis of CdS quantum dots using hairy root culture of Linaria maroccana L. By incubating Linaria root extract with inorganic cadmium sulfate and sodium sulfide we synthesized stable luminescent CdS nanocrystals with absorption peaks for UV-visible spectrometry at 362 nm, 398 nm and 464 nm, and luminescent peaks at 425, 462, 500 nm. Transmission electron microscopy of produced quantum dots revealed their spherical shape with a size predominantly from 5 to 7 nm. Electron diffraction pattern confirmed the wurtzite crystalline structure of synthesized cadmium sulfide quantum dots. These results describe the first successful attempt of quantum dots synthesis using plant extract.

硫化镉纳米粒子在化学研究、生物科学和医学领域具有巨大的应用潜力。本研究的目的是利用摩洛哥柳穿鱼的毛状根培养物，开发一种高效且环境友好的基于植物的硫化镉量子点生物合成方法。通过将柳穿鱼根提取物与无机硫酸镉和硫化钠孵育，我们合成了稳定的发光硫化镉纳米晶体，其紫外可见光谱的吸收峰位于362纳米、398纳米和464纳米，发光峰位于425、462、500纳米。对所制备量子点的透射电子显微镜观察显示其呈球形，尺寸主要在5至7纳米之间。电子衍射图谱证实了合成的硫化镉量子点的纤锌矿晶体结构。这些结果描述了首次使用植物提取物成功合成量子点的尝试。
