아래와 같이 콜로퀴움을 개최하오니 많이 참석해 주시기 바랍니다. 4시부터 2층 라운지세미나실에 다과를 준비하오니 많은 참석 부탁드립니다 아 래 1. 제 목: Novel multi-bit magnetic tagging technique for high-throughput chemical analysis 2. 연 사: 정 종 율 교수(충남대학교) 3. 일 시: 2008년 4월 4일(금) 오후4:30 4. 장 소: 물리학과세미나실(31355호실) 5. 초 록:Convergence between nanotechnology and biotechnology in the last decade has led to interest in the development of miniaturized high-throughput / high-contents screening (HTS, HCS) system for the detection of DNA, protein, cell, virus etc. Therefore a large variety of bioassay/biosensor technologies are either in development or being commercialized and numerous advancements continue to be made in biochip research that enable novel platforms to be developed for new applications. Among the various emerging bioassay technologies, magnetic bioassays, which utilize the high resolution magnetic sensor for the detection of biomolecules, are now attracting much interest because of their unique advantages such as ultrahigh sensitivity, selectivity etc. In this talk, a novel encoding and decoding scheme of micrometer-sized multibit magnetic tags which enables a specific signature to be encoded on each label for performing multiplexed high-throughput bioassays will be introduced. The method is based on the development of digital magnetic encoding techniques that utilize an ensemble of micron-sized ferromagnetic bars and Au patterns. It has far reaching implications related to the development of advanced systems for ultrahigh throughput biological assays that can be used in clinical diagnostics, drug discovery and genome sequencing, etc.
