Abstract:
Mixing aqueous dispersions of thiocyanate ion coated small (<3.5 nm diameter) gold nanoparticles and EDTA covered larger (>22 nm diameter) silver nanoparticles, results in the formation of robust gold encased silver nanoparticles; in contrast to using larger (>11 nm diameter) gold nanoparticles which forms chained structures.1
