We present a fullerene-based strategy that allows the synthesis of molecularly pure miktoarm spherical nucleic acids (SNAs) with diverse structures, which, with post-functionalization, could serve as efficient scaffolds for intracellular catalysis. The SNA structure promotes cell permeability, nucleic acid stability, and catalytic efficiency, making the platform ideal for in cellulo reactions. Consequently
我们提出了一种基于富勒烯的策略,可以合成具有不同结构的分子纯miktoarm球形核酸(SNA),通过后功能化,可以作为细胞内催化的有效支架。 SNA 结构可促进细胞通透性、核酸稳定性和催化效率,使该平台成为纤维素反应的理想选择。因此,带有三(三唑)的 miktoarm SNA 能够有效介导细胞内铜催化的纳摩尔水平的炔-叠氮环加成反应,并促进活体斑马鱼中的相同反应。
