  • Publication number: 20190242911
    Abstract: Disclosed is a measurement method for a glycated hemoglobin ratio. According to a measurement method for a glycated hemoglobin ratio of the present invention, reagents are easy and convenient to use because of their sequential leakage during the rotation of a cassette, are all discharged by the rotation with no remaining reagent, and are not mixed with each other. Therefore, measurement results are accurate, with fewer errors in the quantities of used reagents and sample blood.

  • Publication number: 20190234981
    Abstract: The present invention relates to a separable cassette for measuring glycated hemoglobin. It is easy to use the separable cassette for measuring glycated hemoglobin of the present invention since a reagent is sequentially leaked during the rotation thereof. In addition, there is no need to shake the reagent beforehand, as the reagent without residual reagent is fully discharged by the rotation. Therefore, the measurement result is accurate because an error between the amount of the reagent used and the amount of sample blood is small.

  • Patent number: 9986638
    Abstract: Provided is a method of manufacturing a conductive metal thin film, the method including: a) heating and stirring a first solution containing a metal precursor, acid, amine, and a reducing agent to synthesize metal nano-particles on which formation of a surface oxide film is suppressed; b) dispersing the metal nano-particles synthesize in step a) in a non-aqueous solvent to prepare a conductive ink composition; c) applying the conductive ink composition onto an insulating substrate; and d) heat-treating the insulating substrate applied with the ink composition to form a conductive metal thin film. With the method of manufacturing a conductive metal thin film according to the present invention, large area conductive thin film may be manufactured as compared with the existing conductive ink composition based on noble metal nano-particles. In addition, the conductive metal thin film having excellent conductivity may be manufactured by suppressing a surface oxide film from being formed.
