Here we report the assembly of mixed metal nanoparticles using an oligonucleotide-templated approach. Substitution of one of the gold nanoparticle probes with an analogous silver probe to produce a hetero-metal duplex permitted surface-enhanced Raman scattering of a dye label, exploiting the improved surface enhancement properties of silver nanoparticles whilst maintaining the surface chemistry benefits of gold nanoparticles.
在这里，我们报告了使用寡核苷酸模板方法组装混合金属纳米粒子。用类似的银探针取代一个金纳米粒子探针，以产生杂金属双链体，从而允许染料标记的表面增强拉曼散射，利用银纳米粒子改善的表面增强特性，同时保持金纳米粒子的表面化学益处。
