摘要：

Fluorescent silver nanoclusters were successfully synthesized using hybridized DNA duplexes as capping scaffolds. The formation of these emitters was highly sequence-dependent and could specifically identify a single nucleotide mutation, the sickle cell anemia gene mutation. Furthermore, the identification of single-nucleotide differences using this strategy was extended to more general types of single-nucleotide mismatches.
