We propose linear end-to-end assemblies of short DNA duplexes based on β-cyclodextrinâadamantane complexation. The assembled duplexes exhibited increased Tm values compared with those of the corresponding natural hybrids. Competition experiments with external guest molecules showed a substantial decrease in Tm of the terminal modified duplexes, suggesting the viability of inter-duplex complexation.

金刚烷复合物的短 DNA 双链体的线性端对端组装。与相应的天然杂交体相比,组装后的双链体显示出更高的 Tm 值。与外部客体分子的竞争实验表明,末端修饰的双链体的 Tm 值大大降低,这表明双链体之间的复合是可行的。
