METHOD FOR DETECTING FOOD POISONING BACTERIA USING MAGNETIC NANOPARTICLES AND SOLUTION HAVING HIGH VISCOSITY |
摘要 |
The present invention relates to a method for detecting food poisoning bacteria, and more particularly, to a method for rapidly and quantitatively isolating food poisoning bacteria contents which contaminate food and the like. The method according to the present invention is characterized by including the steps of: introducing magnetic nanoparticles which can bind to bacteria into a sample for measuring the bacteria so as to bind the magnetic nanoparticles to the bacteria; isolating the magnetic nanoparticles; passing the nanoparticles which are isolated by using magnetism through a solution having high viscosity so as to separate the magnetic nanoparticles to which bacteria are bound from magnetic nanoparticles to which no bacteria are bound; and quantifying the magnetic nanoparticles to which bacteria are bound. |

1. A method for quantitatively analyzing bacteria in a sample, comprising:
introducing magnetic nanoparticles capable of capturing bacteria into the sample and allowing the magnetic nanoparticles to capture bacteria; enriching the magnetic nanoparticles from the sample; passing the enriched magnetic nanoparticles through a highly viscous medium in presence of a magnetic field to separate the magnetic nanoparticles into bacterium-complexed magnetic nanoparticles and free magnetic nanoparticles; and quantitating the bacterium-complexed magnetic nanoparticles. |
