Abstract:
PURPOSE: An electrode is provided to improve electron-transfer rate, to increase stability by crosslinking and to have good sensitivity in a low glucose density. CONSTITUTION: An electrode comprises a self-assembled block copolymer with organic metals, and enzyme. The block copolymer is a crosslinked block copolymer. The self-assembled block copolymer and enzyme form a coating layer of 1-50 micron. The amorphously self-assembled block copolymer includes a block including a conductive organic metal. A manufacturing method of the electrode includes a step of mixing the self-assembled block copolymer and enzyme and coating the surface of the electrode with the same.
Abstract:
The present invention relates to a method for measuring copper ions by using the fluorescent substance wherein sulfonated polystyrene is turned into fluorescent substances and, more specifically, a method and a device for selectively measuring copper ions by using the fluorescent substance wherein a block copolymer including the sulfonated polystyrene is turned into fluorescent substances. In the present invention, provided is a fluorescent substance including a block copolymer fluorescent substance including the sulfonated polystyrene block, and a new fluorescent substance based on the block copolymer including the sulfonated polystyrene block. The fluorescent substance of the present invention can control the wavelength and the strength of fluorescence via various methods. The fluorescent substance of the present invention does not need a label and accordingly has no quenching and condensation according to the attachment of the label. The fluorescent substance of the present invention can be used as a new sensor to efficiently measure and detect copper ions without labels, since the property of the fluorescent substance is changed by selectively binding copper ions, and can be used in various light-emitting devices since the fluorescent substance exists in various types.
