提出了合成C60水稳定性胶体聚集体的两种新的溶剂交换方法。这些方法结合了多种现有合成方法的主要优点，包括高产率、窄的粒度分布、控制平均粒度的潜力、合成时间短以及没有四氢呋喃等溶剂，这些溶剂历来在此类聚集体的实验室合成中造成问题。此外，该合成还显示了对C60O对样品的低水平污染的浓缩。所得到的样品是用于受控环境影响、生物学和毒性研究的有吸引力的候选样品。
Two new solvent exchange methods for synthesizing water-stable colloidal aggregates of C60are presented. These methods combine key advantages of multiple existing syntheses, including high yield, narrow particle size distribution, potential for control of mean particle size, short synthesis time, and an absence of solvents such as tetrahydrofuran that have historically caused problems in the laboratory syntheses of such aggregates. Further, the synthesis is shown to enrich low-level contamination of samples by C60O. The resulting samples are attractive candidates for use in controlled environmental impact, biological, and toxicity studies.
