摘要

The invention described relates to the synthesis of gold nanorods in high concentrations in a single batch and their use in detection of nitroexplosives using Surface Enhanced Raman Spectroscopy (SERS). The nanoparticle suspensions were stable up to a month after preparation. The aggregated nanorods have a strong SERS effect for nitroexplosives (3,5-dintro-4-methylbenzoic acid and 2,4,6-TNT) with sensitivity of 5.0 pg in a few seconds. The results obtained in numerous tests demonstrated a high reproducibility that makes aggregated nanorods very attractive substrates for defense and security applications.
