Pushing the Limits of Mercury Sensors with Gold Nanorods

Abstract:
The method presented here provides a direct way to determine mercury in tap water samples at the parts-per-trillion level. Its outstanding selectivity and sensitivity results from the well-known amalgamation process that occurs between mercury and gold. The entire procedure takes less than 10 minutes. No sample separation and/or sample pre-concentration is required. The only step prior to mercury determination consists of mixing the water sample with a gold nanorod solution in sodium borohydride. The analytical figures of merit demonstrate precise and accurate analysis at the parts-per-trillion level. The limit of detection (6.6x10-13 g.L-1) shows excellent potential for monitoring ultra-low levels of mercury in water samples.
