A Noval Magnetic Beadbased Microchip for iFlora Genetic Information Efficient Acquisition System

Magnetic Bead( MB) has been widely applied in life science for its high surface area,coupling capacity with biomolecules and convenience of being manipulated. With the development of Micro Electro Mechanical systems( MEMS) technologies,MB-based bio-microsystem provide a new approach for separation and detection of biological samples. Integrating modern DNA sequencing technologies and applying high-speed computer digitization,network technology and cloud computing analysis platform for collection and management of species information,the next-generation Flora,or iFlora is an intelligent application system for plant species identification and related information acquisition. Efficient genetic information acquiring technology is key in building iFlora. This paper briefly introduces the MB-based bio-microsystem technology and its application in molecular biology. The authors suggest a new MB-based bio-microsystem iFlora genetic information collection system. Combined with MB technology,the total analy-ses from cell lysis to DNA sequencing will be achieved on microchip,which will realize the quick and efficient ac-quirement of genetic information.
