Abstract/OtherAbstract:
|
A strategy for rapid and facile detection of melamine in food and other substances is described. Unmodified gold nanoparticles enable a colorimetric signal output that is amplified through integration by precipitation formation via a chemical component specific to melamine. The sensitivity was determined to be approximately 40 ppb with a two standard deviation cutoff. |
