Abstract: The present invention relates to a membrane sensor having a multi-hole film attached thereto and a method for measuring immunological reactions or enzymatic reactions using the same. More specifically, the present invention relates to a membrane sensor in which a multi-hole film is joined to the top of a membrane on which receptors are immobilized, and a method for measuring immunological reactions or enzymatic reactions using the same.

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.

Abstract: Disclosed is a method for activating a catalyst using the photothermal effects of photothermal nanomaterials, and more particularly to a method of activating a catalyst at a temperature, at which the catalyst has low or no activity, by irradiating a catalyst-photothermal nanomaterial composite with light. The method can activate the catalyst by increasing only the temperature around the nanomaterials without substantially changing the temperature of the reaction medium. A catalyst that generally has high activity at room temperature can be activated even at low temperature. Catalysts having high activity only under mild conditions are immobilized on photothermal nanomaterials so that they have activity even under low temperature and extreme conditions. The invention is useful when a catalyst substrate unstable at room temperature is used or a catalytic product unstable at room temperature is produced.
