项目摘要

TITLE: Development of a charge sensitive optical detection system for high-throughput study of small molecules SUMMARY Measuring the kinetics of small molecule binding to protein receptors and biochemical reactions of proteins, such as post-translational protein modifications, is a basic task in the understanding of diseases, discovering of diagnosis biomarkers, and screening of drugs. Various label-free techniques have been developed, but their sensitivity decreases with the molecular mass, which makes it challenging to detect small molecules and biochemical reactions. A charge sensitive optical detection (CSOD) system is proposed to address this unmet need. The technology is not only sensitive to small molecules, but also compatible with the standard microplate technology, which is particularly suitable for high-throughput applications. The working principle was established and validated with the support of NIH NCI IMAT (Innovative Molecular Analysis Technologies for cancer research) grants (R21 and R33) to the Arizona State University (ASU) team. In this SBIR direct phase II project, Biosensing Instrument Inc. (BI) will work with the ASU team to develop a commercially viable prototype system. We will continue collaborations with potential customers in biomedical research and pharmaceutical industries for testing samples relevant to their interest and validating the performance usability of the developing system. The success of the project will lead to a new high-throughput screening technology for measuring molecular interactions, particularly small molecule interactions with proteins, and post-translational modifications of proteins. These processes are highly important for biomarker discovery, disease diagnosis and drug screening.

标题：开发用于小分子高通量研究的电荷敏感光学检测系统概括测量小分子与蛋白质受体结合的动力学和蛋白质的生化反应，例如作为翻译后蛋白质修饰，是理解疾病、发现疾病的一项基本任务诊断生物标志物和药物筛选。已经开发了各种无标记技术，但它们灵敏度随着分子质量的增加而降低，这使得检测小分子和生化反应。提出了电荷敏感光学检测（CSOD）系统来解决这个未满足的问题需要。该技术不仅对小分子敏感，而且与标准微孔板兼容技术，特别适合高通量应用。工作原理确立并在 NIH NCI IMAT（癌症创新分子分析技术）的支持下进行了验证研究）向亚利桑那州立大学（ASU）团队提供资助（R21 和 R33）。在这个SBIR直接二期项目中， Biosensing Instrument Inc. (BI) 将与 ASU 团队合作开发商业上可行的原型系统。我们将继续与生物医学研究和制药行业的潜在客户合作用于测试与其感兴趣的相关样本并验证开发系统的性能可用性。该项目的成功将带来一种新的高通量筛选技术，用于测量分子相互作用，特别是小分子与蛋白质的相互作用，以及翻译后修饰蛋白质。这些过程对于生物标志物发现、疾病诊断和药物筛选非常重要。
