## Abstract The 5 nm AuPd nanoalloy in mole ratio of Au:Pd=32:1 was prepared, using sodium citrate as the stabilizing agent and NaBH~4~ as the reductant. The AuPd nanoalloy was modified by the aptamer to prepare an aptamerβ AuPd (AptAuPd) probe for resonance scattering (RS) detection of 5.0β1250 nm

## Abstract Herring sperm DNA (hsDNA) was used to modify 10βnm nanogold to obtain a resonance scattering (RS) probe (AuhsDNA) for detection of Hg^2+^. In the presence of salt, Hg^2+^ interacts with AuhsDNA to form stable Hg^2+^βhsDNA complexes, and releases nanogold particles to form larger nanogol
