    • The present invention relates to a method of rapidly detecting microorganisms using nanoparticles, and more particularly to a method and device of rapidly detecting microorganisms by adding, to the microorganisms to be detected, nanoparticles having immobilized thereon an antibody that binds specifically to the microorganisms to be detected, subjecting the mixture to an immune reaction to form a reaction solution, passing the reaction solution through a microorganism-concentrating film to concentrate the microorganisms, capturing microorganisms, which was immune-reacted with the antibody-immobilized nanoparticles, by a microorganism-capturing filtration membrane, and determining the presence and concentration of the microorganisms.The present invention detects microorganisms using nanoparticles having immobilized thereon an antibody that binds specifically to the microorganisms to be detected, so that the presence and concentration of the microorganisms can be determined in a more effective and simpler manner than a conventional detection method, and the inventive method is effective in detecting a small amount of microorganisms owing to high sensitivity.
    • 本发明涉及使用纳米颗粒快速检测微生物的方法,更具体地说,涉及通过向被检测微生物添加特异性地与微生物结合的抗体的纳米颗粒来快速检测微生物的方法和装置。 检测到,使混合物进行免疫反应以形成反应溶液,使反应溶液通过微生物浓缩膜以浓缩微生物,通过微生物捕获捕获与抗体固定的纳米颗粒免疫反应的微生物 过滤膜,并确定微生物的存在和浓度。 本发明使用其上固定有特异性地与待检测微生物结合的抗体的纳米颗粒来检测微生物,从而可以以比现有的检测方法更有效和更简单的方式确定微生物的存在和浓度。 方法由于高灵敏度而有效地检测少量的微生物。

    • The present invention relates to a biosensor capable of a trace amount of sample and a fabrication method thereof. More specifically, the invention relates to a method for fabricating a biosensor, the method comprising: immobilizing a receptor molecule, which binds selectively to a target substance, on an electrically insulated nano-electrode chip; binding an enzyme to the receptor molecule; and treating the bound enzyme with metal ions and depositing the metal ions on the nano-electrode surface, and to a biosensor fabricated thereby. According to the invention, a precipitate is produced on the nano-electrode surface by a precipitation between the enzyme and the metal ions, and the produced precipitate electrically connects the nano-electrodes together, thereby increasing electrical conductivity. Thus, the invention is useful for quantitative analysis of trace amounts and/or various concentrations of target substances.
    • 本发明涉及能够追踪微量样品的生物传感器及其制造方法。 更具体地说,本发明涉及一种制造生物传感器的方法,该方法包括:在电绝缘的纳米电极芯片上固定与靶物质选择性结合的受体分子; 将酶与受体分子结合; 并用金属离子处理结合的酶并将金属离子沉积在纳米电极表面上,以及由其制造的生物传感器。 根据本发明,通过酶和金属离子之间的沉淀在纳米电极表面上产生沉淀物,并且所产生的沉淀物将纳米电极电连接在一起,从而增加导电性。 因此,本发明可用于痕量和/或各种浓度的目标物质的定量分析。
