| titleOfInvention | Method for visually detecting melamine by using aptamer-free nanogold hydrosol |
| abstract | The invention discloses a method for visually detecting melamine by using aptamer-free nanogold hydrosol, which comprises the steps of adding plants into absolute ethyl alcohol, boiling, extracting and filtering to obtain filtrate; adding activated carbon into the filtrate for decolorization, and standing for 1 day to obtain light yellow plant extract; diluting the light yellow plant extract, and storing the obtained diluent for later use; and (3) adding a sample to be detected into the diluent, uniformly mixing, adding a chloroauric acid aqueous solution, adjusting the pH value, reacting, and detecting melamine by a visual colorimetry or an ultraviolet-visible spectrophotometry. The detection method is rapid, simple and convenient, high in sensitivity and strong in anti-interference capability, and the detection limit of the melamine can reach 15 nM. The method can perform visual detection on the melamine sample, can adopt sampling detection on site, has high detection flexibility, and can realize qualitative and quantitative detection of the melamine. And the sample under the adverse circumstances can be detected, and the sample application scope is wide. |
