基于高荧光碳纳米粒子的Fe3+超灵敏检测
Highly Fluorescent Carbon Nanoparticles for Sensitive Detection of IronⅢ
摘要
Abstract
A simple preparative strategy was proposed for the preparation of water-soluble, bright blue-emitting carbon nanoparticles ( CNPs ) at different temperatures by hydrothermal treatment using bean curd residue as carbon source for the first time. When the temperature reaches 240 ℃, quantum yield ( QY) can be up to 15. 24%. Most importantly, such fluorescent CNPs can be served as an effective sensing platform for label-free sensitive and selective detection of Fe3+ions with a detection of limit as low as 50 nmol/L, which is nearly 2 orders of magnitude lower than the maximum level of Fe3+ions in the drinking water permitted by the European Community. These outstanding properties give promising potential for reliable detection of Fe3+ in intracellular fluid and water samples, even bioimaging and optical imaging without being hazard in the future.关键词
