Molecular beacon-functionalized gold nanoparticles as probes in dry-reagent strip biosensor for DNA analysis

The highly specific molecule recognition properties of molecular beacons (MB) are combined with the unique optical properties of gold nanoparticles (Au-NPs) for the development of a dry-reagent strip-type nucleic acid biosensor (DSNAB) that enables sensitive and low-cost detection of nucleic acid samples within 15 min.
