利用天然生物质水热合成碳量子点（CQD）是CQD在各个领域应用的绿色可持续路线。在这项工作中，研究了基于藜麦皂苷的 CQD 的制备和表征。经正交实验确定最佳合成条件为：2g藜麦皂苷粉与0.04mol乙二胺在200℃反应10h。可以获得相对荧光量子产率（QY = 22.2%），高于文献报道的一些结果。制备的 CQD 具有小且均匀的尺寸（~2.25 nm），并表现出激发波长依赖性的蓝光发射行为。 CQD 对 Co2+ 检测表现出优异的灵敏度，在 20 至 150 µM 范围内具有良好的线性相关性，检测限为 0.49 µM。本实验制备的CQDs成功植入豆芽中进行荧光成像。即使在CQDs溶液中浸泡两周，芽苗仍能健康生长，证明了CQDs的低毒性。 CQD具有成本低、易于制造、无毒和稳定性等优点，在金属离子检测和生物传感等许多领域具有潜在的应用前景。
Hydrothermal synthesis of carbon quantum dots (CQDs) from natural biomass is a green and sustainable route for CQDs applications in various fields. In this work, the preparation and characterization of CQDs based on quinoa saponin were investigated. The optimum synthetic conditions determined by orthogonal experiments were as follows: 2 g quinoa saponin powder and 0.04 mol ethylenediamine reacted at 200°C for 10 h. The relative fluorescence quantum yield (QY = 22.2%) can be obtained, which is higher than some results reported in the literatures. The prepared CQDs had a small and uniform size (∼2.25 nm) and exhibited excitation wavelength-dependent blue light emission behavior. The CQDs displayed excellent sensitivity for Co2+ detection along with good linear correlation ranging from 20 to 150 µM and the detection limit of 0.49 µM. The CQDs prepared in this experiment were successfully implanted into soybean sprouts for fluorescence imaging. The sprouts could grow healthily even soaked in the CQDs solution for two weeks, demonstrating the low toxicity of the CQDs. The advantages of the CQDs, such as low cost, ease of manufacture, nontoxicity, and stability, have potential applications in many areas such as metal ion detection and biosensing.
