A novel strategy is described for highly sensitive DNA detection and point mutation identification based on the combination of reverse molecular beacon with DNA ligase. A 5'-phosphoryl and 3'-ferrocene terminated DNA sequence is used as detection probe, which may be ligated to capture DNA immobilize
## Abstract The present study reports a proofโofโprinciple for a sensitive genotyping assay approach that can detect single nucleotide polymorphisms (SNPs) based on fluorescence anisotropy measurements through a coreโshell fluorescent nanoparticles assembly and ligase reaction. By incorporating the
