The selective detection of Fe 3+ ions using citrate-capped gold nanoparticles
Citrate is a ubiquitous biological molecule that functions as Fe chelators in some bacteria and the blood plasma of humans. Inspired by the strong affinity between citrate and Fe , a colorimetric Fe probe based on citrate-capped AuNPs without any additional modification was designed. Citrate-capped...

| description | Citrate is a ubiquitous biological molecule that functions as Fe
chelators in some bacteria and the blood plasma of humans. Inspired by the strong affinity between citrate and Fe
, a colorimetric Fe
probe based on citrate-capped AuNPs without any additional modification was designed. Citrate-capped AuNPs with a diameter of 22 nm were applied to detect Fe
without other reagents' assistance. This easily-prepared and low-cost colorimetric sensor exhibited good selectivity towards Fe
among common metal ions, a good linear relationship in the range of 0.1-0.8 μM of Fe
and quick response time of 10 min. |
