Abstract:
A three-dimensional micro/nano-structure is provided to be able to increase the sensitivity of a biochip without non-specific absorption by having an active enzyme, thereby increasing the reliability of a bio-sensor. The three-dimensional nano-structure includes a functional enzyme which is controllably prepared by layer-by-layer assembling of surface templates patterned by using the micro-contact printing manner. The method comprises the steps of: (a) printing an SAM strip as a resistant coating agent on a substrate having a cold surface; (b) filling an un-stamped area with an SAM which is made of biotin-terminated thiol; (c) assembling avidin on the biotinylated SAM area; and (d) binding a biotin-HRP to the avidin, wherein the steps (c) and (d) are repeated.
Abstract:
A preparation method of ITO(indium tin oxide) synthesis composition is provided to apply the composition to ITO synthesis and ITO patterning processes and to derive formation of nano-scale structure through the ITO patterning and use of electron beam by using indium tert-butoxide and tin tert-butoxide as a precursor of the composition. The composition is produced by the steps of: forming first solution by mixing indium tert-butoxide, 1-benzoylacetone and methanol; forming second solution by mixing tin tert-butoxide, 1-benzolacetone and methanol; and blending the first solution and the second solution together. The first solution is obtained by admixing indium tert-butoxide and 1-benzoylacetone in 1:1 ratio, then adding methanol to the admixture. The second solution is obtained by admixing tin tert-butoxide and 1-benzoylacetone in 1:1 ration, then adding methanol to the admixture. All of the steps are conducted in a glove box with relative moisture of less than 5%.

Abstract:
본 발명은 신규한 FRET (fluorescence resonance energy transfer) 시스템에 관한 것이다. 본 발명의 FRET 시스템은 공여체로서 QD (quantum dot) 및 수용체로서 염료-표지된 DNA로 구성되어 있다. 본 발명의 공여체와 수용체는 티올 링커로 직접 커플링되어 있다. 이러한 직접적인 커플링은 공여체-수용체 거리를 감소시킴으로써 고도로 향상된 FRET 효율을 유도하게 된다. 본 발명에 따르면, 2의 낮은 수용체-대-공여체 비에서 고도로 효율적인 FRET (~88%)이 단일-분자 수준에서 달성되었다.
