A kind of multifunctional electrochemical sensor and preparation method thereof

Abstract

The invention relates to the field of electrochemistry, and concretely relates to a multifunctional electrochemical sensor for simultaneously realizing capture, sterilization and detection, and a making method thereof. The sensor is ZnO nanorods loaded with AgNPs and vancomycin, wherein a mass ratio of the AgNPs to the vancomycin is 1:1 to 1: 6. The preparation method has the advantages of simple process, easiness in control and low cost, and allows the multi-functional electrochemical sensor for simultaneously realizing capture, sterilization and detection to be produced. The synergistic effect of the vancomycin and nano-silver is used to highly-efficiently kill the harmful microorganisms in water and separate and detect pathogens in the water, so the sensor has very good application prospect in the field of water purification.

Description

technical field

[0001] The invention belongs to the field of electrochemistry, and in particular relates to a multifunctional electrochemical sensor capable of capturing, sterilizing and detecting at the same time and a preparation method thereof. Background technique

[0002] Every year, many people die from bacterial water pollution, such as "super bacteria" pollution and so on. If bacterial contamination can be diagnosed quickly and the bacteria killed quickly, the mortality rate of bacterial infection will be greatly reduced [1].

[0003] Electrochemical biosensor is an analytical method based on solid electrodes and biologically sensitive molecules. Because electrochemical sensors have the advantages of high efficiency, simplicity, easy operation and low cost, electrochemical sensors have been widely used in the analysis of DNA [2] and viruses [3]. Among many bacterial detection technologies, electrochemical biosensors have attracted widespread attention. For example,...
