Abstract: A system and method for converting carbon dioxide are proposed. The system for converting carbon dioxide includes a carbon monoxide generator for generating carbon monoxide through a reverse water gas shift reaction and a hydrocarbon generator for producing a hydrocarbon through a Fischer-Tropsch synthesis reaction, whereby the carbon monoxide generator is packed both with a catalyst for the reverse water gas shift reaction and with a catalyst for the Fischer-Tropsch synthesis reaction, thus increasing the CO yield in the carbon monoxide generator even at a low temperature compared to when the catalyst for the reverse water gas shift reaction is used alone, ultimately increasing the hydrocarbon yield in the hydrocarbon generator. Moreover, the energy of the exothermic Fischer-Tropsch synthesis reaction can be used as the energy required for the endothermic reverse water gas shift reaction, thereby increasing energy efficiency and processing yield and thus reducing operation and maintenance costs.

Abstract: The present invention relates to an electrode for a biosensor for NADH measurement and a manufacturing method therefor. An electrode manufactured by the method according to the present invention enjoys the advantages of stabilizing current flow during an electric polymerization reaction, making the contact angle of the modified material remarkably small to increase the efficiency of surface modification, and being reusable several times. In addition, when applied to a biosensor for NADH measurement, the electrode of the present invention maintains sensitivity and selectivity at a high level without interference and thus easily measures a target of interest even in blood or serum that necessarily requires a pretreatment process due to the existence of a trace amount of a material to be measured. In addition, when applied to a biosensor for NADH measurement, the electrode can measure cell viability in a continuous manner and in real time, which leads to the application thereof to the cell toxicity assay field, and enables the measurement of cell viability in apoptotic cells lacking the mitochondrial function.
