    • The present invention relates to a production method for an epoxy substrate exhibiting a nanopattern, comprising the stages of: (a) forming a titanium oxide film by anodization of a titanium substrate; (b) obtaining a titanium substrate having a concave shape formed on its surface by removing the titanium oxide film from the titanium substrate on which the titanium oxide film has been formed; (c) coating an epoxy resin onto the titanium substrate on which the concave shape has been formed; and (d) obtaining an epoxy substrate formed with a nanopattern of convex surfaces by removing the titanium substrate. In the production method of the present invention, an epoxy substrate formed with a nanopattern of convex surfaces is produced after anodizing titanium, coating an epoxy resin onto a nanopattern formed with a concave shape on the titanium surface, and removing the titanium substrate. This straightforward process makes it possible to efficiently produce an epoxy resin exhibiting a nanopattern for the measurement of blood coagulation formed with a fine pattern which is uniform and on the nano scale. Further, the epoxy substrate produced by means of the present invention makes it possible to efficiently use an electrochemical technique to ascertain whether or not blood coagulation is present in a blood sample.
    • 本发明涉及一种表现出纳米图案的环氧树脂基板的制造方法,其特征在于,包括:(a)通过钛基板的阳极氧化而形成氧化钛膜; (b)从形成有氧化钛膜的钛基板上除去氧化钛膜,得到表面形成有凹形状的钛基板; (c)将环氧树脂涂布到已经形成凹形的钛基板上; 和(d)通过除去钛基材得到形成有凸面的纳米图案的环氧树脂基材。 在本发明的制造方法中,在阳极氧化钛之后,在钛表面上涂布环氧树脂到形成为凹形的纳米图案上,并除去钛基板,制作形成有凸面的纳米图案的环氧树脂基板。 这种直接的方法使得可以有效地制备出显示用于测量均匀且纳米尺度的精细图案形成的凝血的纳米图案的环氧树脂。 此外,通过本发明制造的环氧树脂基板使得可以有效地使用电化学技术来确定血液样品中是否存在凝血。

    • The present invention relates to core-shell nanoparticles comprising: a manganese-containing magnetic nanoparticle (Mn-MNP) multi-core; and a silica shell coating the multi-core. Since the core-shell nanoparticles used in the present invention have high saturation magnetization (Ms) value and transverse relaxivity (R2), a sensor of the present invention using the same can detect analytes with remarkably improved sensitivity. It is possible to detect a trace amount of analytes, for example, a protein or a nucleic acid molecule as an anti-cancer marker in the blood, a chemical material, and the like with the improved sensitivity. Therefore, the core-shell nanoparticles of the present invention can be useful in an effective and practical magnetic nanoparticle system and a magnetic sensing method or a contrast medium using the same due to excellent magnetic characteristics, in vivo non-toxicity, high solubility and easy surface modification.
