  • Patent number: 9465003
    Abstract: A membrane electrode includes a novel sensor combining a filtering function of a membrane and a signal measuring ability of an electrode. A target material may be measured by filtration through the membrane. A small amount of target materials may be detected with high sensitivity using an amplified electrical signal by increasing electrical conductivity by reducing metal ions on the membrane, and thus the target material may be subject to quantitative analysis. In addition, only a target material selectively binding to a receptor may be filtrated by passing a sample through the membrane after a receptor material is fixed to the electrode, and thus may be used to detect an electrical signal. In addition, the sensor may measure a signal in various methods such as electrical conductivity, impedance, etc.
