The AuRe nanoalloy particles in molar ratio of 9βΆ1 were prepared by sodium borohydride procedure, and modified by single strand DNA (ssDNA) to prepare an aptamer AuRe nanoprobe (AuRessDNA) for Hg 2οΌ . In the pH 7.0 Na 2 HPO 4 -NaH 2 PO 4 buffer solution and in the presence of NaCl, Hg 2οΌ interacted

## 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
