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.

Abstract: The present invention relates to a composition for the prevention, amelioration, or treatment of urination-related disases, comprising cephalotocin. The cephalotocin according to the present invention modulates oxytocin receptors and vasopressin receptors, and has the effect of reducing urine volume by promoting water reabsorption in the kidneys. This means that cephalotocin has a significant antidiuretic effect, and thus, the cephalotocin of the present invention can be variously used in the field of prevention, amelioration, or treatment of urinary disorders or urination-related diseases.

Abstract: The present invention relates to a temperature-change sensing substrate comprising a self-healing polyurethane polymer. More specifically, the present invention relates to a temperature-change sensing substrate having a self-healing polyurethane polymer matrix and a plurality of pores dispersed in the matrix. The temperature-change sensing substrate according to the present invention can be applied as a temperature-change sensor for preventing the spoiling of refrigerated or frozen food and medical supplies. For example, substrate, which was opaque when stored at −60° C., −50° C., −30° C., −20° C., −10° C. and the like, becomes transparent if the temperature rises to 0° C., 10° C., 20° C., 30° C. and the like, and thus a temperature-change sensor capable of checking storage conditions through a change in light transmittance can be provided.
