| titleOfInvention | DNA electrochemical biosensor for detecting lead |
| abstract | The invention discloses a DNA electrochemical biosensor for detecting lead, which is characterized in that a sensitive film consisting of GR5-DNAzyme and MXene nanosheets is modified on the surface of a glassy carbon electrode; will react to Pb 2+ DNase GR5-DNAzyme with specific reactivity is used as a reaction element, and the characteristics of different affinities of a new two-dimensional transition metal carbide material MXene to single and double DNA chains are utilized to construct a new material for Pb on a glassy carbon electrode GCE 2+ High sensitivity electrochemical biosensor for detection. The sensor is simple and rapid to operate, and can sensitively and efficiently detect the lead content in animal tissues. The method can be used for quickly measuring the lead content in animal-derived food, and provides a technical support for effectively controlling the harm and pollution of heavy metals to the environment, animal organisms and livestock products in the livestock and poultry production link. The biosensor has good recovery rate, and can be used for Pb in actual samples 2+ Detecting and at low concentration for Pb 2+ Has better reaction. |
