아래와 같이 콜로퀴움을 개최하오니 많이 참석해 주시기 바랍니다. 4시부터 2층 라운지세미나실에 다과를 준비하오니 많은 참석 부탁드립니다 아 래 1. 제 목: DNA 나노기술(DNA Nanotechnology) 2. 연 사: 박 성 하 교수( 성균관대학교 물리학과 ) 3. 일 시: 2008년 5월 30일(금) 오후4:30 4. 장 소: 물리학과세미나실(31355호실) 5. 초 록: Although it is well known as molecules for storage of genetic information in biology, DNA has also been recognized as an efficient building material in the field of DNA nanotechnology. DNA nanotechnology has been attractive as a novel assembly method for fabricating nanostructures for the last two decades. DNA molecules provide basic building blocks for constructing functionalized nanostructures with two major features: self-assembly and programmability. In this talk, we present on self-assembled DNA nanostructures, DNA-templated metallic nanowires, and DNA algorithmic self-assembly. 1D and 2D periodically patterned nanostructures utilizing several distinct DNA motifs such as cross tiles, double crossover tiles as well as single-stranded tiles will be discussed with unique design schemes and characteristics. We have demonstrated fabrication of size-controllable, fully addressable, and precisely programmable DNA-based nanostructures. Especially in construction of “working“ devices, properly designed DNA lattices can serve as a controllable and programmable scaffold for organizing nanomaterials such as protein or nanoparticles. DNA-templated metallic nanowires using a chemical deposition method might be a good example. We discuss electrical measurement through silver nanowires and propose possibilities of the construction of electronic devices such as single electron transistors or spin-related devices based on DNA lattice. Finally we talk about DNA algorithmic self assembly which has been proposed as an effective method for the bottom-up fabrication of complicated patterns. In order to achieve an algorithmic DNA crystal with relatively low error rates and high crystal nucleation, we introduce a rationally designed error correction scheme of a proofreading crystal and a rigid nucleating structure.
