英文摘要 | An ultra-sensitive sensor was fabricated to measure dopamine through quenching and restoring FITC fluorescence by the competitive binding of dopamine and N-acetylneuraminic acid with mercaptophenylboronic acid anchored on the gold nanoparticles. Assessed by quantifying dopamine in human urine samples, it reached a limit of detection of as low as 50 pM dopamine over a linear range from 10(-10) M to 10(-7) M. It also features low technical barriers and operation cost, and the strategy proposed could be extendable to other analytes and not restricted to the gold nanoparticles. |
