Micro sensor-based antibiotic detection device and manufacturing method thereof as well as micro sensor-based antibiotic detection method

Abstract

The invention discloses a micro sensor-based antibiotic detection device and a manufacturing method thereof as well as a micro sensor-based antibiotic detection method. The micro sensor-based antibiotic detection device comprises a micro sensor and a picoammeter with a voltage output function, wherein the voltage output end of the picoammeter is connected with an electrode interface of the micro sensor; a working electrode of the micro sensor is coated with a PFSA (perfluorinated sulfonic acid) macromolecular film; and magnetic nano core-shell type microspheres are embedded into the PFSA macromolecular film. By use of the high adsorption performance of the magnetic nano core-shell type microspheres and the advantages of quick response, small sample use amount, high interference resistance and the like of the micro sensor, the micro sensor-based antibiotic detection device can realize effective, simple, quick and accurate detection for the concentration of antibiotics in a liquid phase.

AI Technical Summary

Benefits of technology

This new technology uses magnetism for detecting small particles called nanoparticles that are attached to tiny metal shells or beads made from plastic material. These special materials have strong affinity towards specific substances like bacteria but they also respond quickly even at very low concentrations (<10 ppb). They provide an easy way to measure these levels accurately without relying on complicated methods such as spectroscopic analysis.

Problems solved by technology

This patents discusses different methods for detecting antimicrobial agents present at various stages during their lifecycle from animal husbandry to food consumption. These techniques include advanced analysis tools like High Performance Liquids Chromatography(HPLC)and Surface Enhanced Ramans Spectroscopic Scanning Fluorescent Lamp Dispersive X Ray Absorption Spectrum Analyzer (SEXAS). However, these existing methods require complicated operations, slow response times, difficult handling, and may result in reduced reliance due to instabilities caused by external influences. There remains a significant challenge towards finding simpler ways to quickly identify and measure antifungals without affecting other natural resources.
