DESCRIPTION (provided by applicant): The goal of this research project is to develop a new technology for microarray analysis that has superior performance and is more affordable than the currently available fluorescence-based microarrays. In Phase-I we have provided proof-of-principle for the proposed approach of reading a DNA microarray produced directly on the surface of a computer diskette. With this approach, a modified disk drive of a personal computer can be used as a reader device. Potential applications of this new technology can include: (1) Creating new diagnostic classifications based on gene expression; (2) Discovery of signaling pathways and new targets of therapy; (3) Developing new markers of diseases; (4) Monitoring of treatment response and selection of the most appropriate therapy. During Phase II, we will produce a commercial prototype of the Magnetic Array System and, after careful evaluation and validation in Phase-II, we will make this system available for commercial production in Phase III. The objectives in Phase II will be achieved through the specific aims established as following: (1) The Magnetic Array System will be optimized by upgrading Array Reader Electronics; by developing a methodology for automated data filtering and quantitative characterization of the quality of the microarray data; and by introducing 3D-linker technology for producing high-performance microarrays in a format compatible with the magnetic array reader. (2) Microarray processing protocols will be finalized and a pilot production of the focused microarrays will be established for applications in cancer research. (3) The performance of the prototype of the Magnetic Array System will be evaluated through collaboration with research groups in academic institutions. For successful completion of Phase-II, Sci-Tec Inc. has established collaboration with academic institutions and businesses including the Material Analysis Center at Oak Ridge National Laboratory, the Medical Center of the University of Tennessee, the E.O. Lawrence Berkeley National Laboratory, Link Instruments (Fairfield, NJ), Zylux (Oak Ridge, TN), and Southeast Community Capital, a venture capital company organized to help and assist new technology businesses.

描述(申请人提供)：本研究项目的目标是开发一种新的微阵列分析技术，该技术具有优越的性能，并且比目前可用的基于荧光的微阵列更实惠。在第一阶段，我们为读取直接在计算机磁盘表面产生的DNA微阵列的拟议方法提供了原则证明。利用该方法，个人计算机的经修改的盘驱动器可以用作读取器设备。这项新技术的潜在应用包括：(1)根据基因表达创建新的诊断分类；(2)发现信号通路和新的治疗目标；(3)开发新的疾病标记物；(4)监测治疗反应和选择最合适的治疗方法。 在第二阶段，我们将生产磁性阵列系统的商业原型，经过第二阶段的仔细评估和验证，我们将在第三阶段将该系统投入商业生产。第二阶段的目标将通过以下具体目标实现：(1)通过升级阵列读取器电子设备来优化磁性阵列系统；通过开发自动数据过滤和微阵列数据质量的量化表征的方法；以及通过引入3D-Linker技术，以与磁性阵列读取器兼容的格式生产高性能的微阵列。(2)将最后确定微阵列处理方案，并将建立用于癌症研究的重点微阵列的试生产。(3)通过与学术机构的研究小组合作，对磁阵系统原型的性能进行评估。 为了成功完成第二阶段，Sci-Tec Inc.已经与学术机构和企业建立了合作关系，其中包括橡树岭国家实验室的材料分析中心、田纳西大学的医学中心、E.O.劳伦斯·伯克利国家实验室、林克仪器公司(新泽西州费尔菲尔德)、Zylux(田纳西州橡树岭)和东南社区资本公司，这是一家旨在帮助和协助新技术企业的风险投资公司。
