## 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 aptamer‐ AuPd (AptAuPd) probe for resonance scattering (RS) detection of 5.0–1250 nm

The AuRe nanoalloy particles in molar ratio of 9∢1 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
