title: A facile method for preparation of gold nanoparticles with high SERS efficiency in the presence of inositol hexaphosphate.
abstract: This paper described a facile method for preparation of gold nanoparticles with high efficient SERS activity within short reaction time in the presence of an environmentally benign and low-cost reagent named inositol hexaphosphate (IP(6)). IP(6) acted as a tunable cross-linker to obtain a suitable separation (about 2nm) between the neighboring particles for certain surface plasmons by adjusting the dosages of IP(6). When the molar ratio of Au to IP(6) was 10:1, gold particles presented in nano-pearl-necklace pattern, demonstrating the high enhancement factor (>10(7)) for 2-mercaptopyridine (2-Mpy) Raman scattering and high stability (>2months).
