量子点配体的交换方法以及用于量子点配体交换的装置
摘要：
本发明涉及纳米粒子制备领域，特别涉及量子点配体的交换方法及装置。所述交换方法为：将颗粒状的表面附着有第一配体的量子点装入柱式管中；使置换液通过所述柱式管，对量子点表面附着的第一配体进行置换，得到表面附着有第二配体的量子点：使淋洗液通过所述柱式管，对表面附着有第二配体的量子点进行洗脱；收集并检测经过柱式管后的淋洗液对检测结果进行判断，若经过柱式管后的淋洗液中不含有所述表面附着有第二配体的量子点，则重复步骤上述步骤；若经过柱式管后的淋洗液中含有所述表面附着有第二配体的量子点，则定量分析量子点表面附着的第二配体的含量。所述交换方法实现了量子点表面配体的有效置换，量子点稳定，表面的第二配体可定量。
摘要（英）：

The present disclosure provides a method and a device for exchanging quantum dot ligands. The method includes: loading, into a column tube, granular quantum dots to whose surface a first ligand is attached; passing a replacing liquid through the column tube to replace the first ligand attached to the surface of the quantum dots, so as to obtain quantum dots to whose surface a second ligand is attached; passing an eluent through the column tube to elute the quantum dots to whose surface the second ligand is attached; collecting the eluent passed through the column tube; and detecting whether the eluent passed through the column tube contains the quantum dots to whose surface the second ligand is attached, if no, repeating the above step, and if yes, quantitatively analyzing the content of the second ligand attached to the surface of the quantum dots.
