This Small Business Innovation Research Phase I project will develop and demonstrate a high throughput flow cell array for use with a variety of label-free biosensing platforms, but primarily SPR systems. Flow cell technology is currently the limiting factor in the development of high throughput label-free sensing technologies. Modification of Wasatch Microfluidics Continuous Flow MicrospotterTM into a highly parallel flow cell should begin to eliminate this bottleneck and provide a template for even more highly parallel systems. The research performed in this project will specifically help us understand the differences between different pumping technologies and their ability to be integrated with the flow cell. Preliminary work suggests that a flow cell array can convert mediocre SPR imaging instruments into highly-competitive protein analysis instruments comparable to state-of-the-art SPR instruments with meager throughput. We will also develop an understanding of how the flow cell technology will impact the sensing capabilities of a surface plasmon resonance (SPR) instrument, and an optimized baseline protocol will be developed. The end result will be a 48 channel flow cell, which will be scalable to much higher throughputs (192, 1536). This flow cell will be generic such that it will be easily integrated with a variety of label-free sensing technologies. The end result of this research and development effort will be a flow cell array with more than double the capacity of the best current systems and will lay the ground work for much higher density systems.The broader impacts of this technology include the commercial opportunities of the microfluidic flow cell array (MFCA). The MFCA will be developed for integration with the biosensing platforms of a number of other companies. Specifically we will target labelfree technologies used to measure kinetic and affinity constants for binding of molecules to one another. This is currently a $100M/year market. From our discussions with pharmaceutical companies, higher throughput label-free systems will lead much larger implementation of these technologies and a significant commercial potential, including a significantly larger market. Even the most basic implementation of our flow cell will have a substantial impact. Currently, it takes the flagship Biacore instrument 28 hrs to process 384 samples. These same 384 samples would only take 1 hr with our new flowcell. These same instruments will then lead to substantially faster and more effective drug discovery processes, and eventually better health for the US population.

这个小型企业创新研究第一阶段项目将开发和展示一种高通量流动池阵列，用于各种无标记生物传感平台，但主要是SPR系统。流动池技术目前是高通量无标记传感技术发展的限制因素。将Wasatch Microfluidics Continuous Flow MicrospotterTM改造成高度平行的流动池，应该开始消除这一瓶颈，并为更高度平行的系统提供模板。本项目中进行的研究将特别帮助我们了解不同泵送技术之间的差异及其与流动池集成的能力。初步工作表明，流动池阵列可以将平庸的SPR成像仪器转换为具有高竞争力的蛋白质分析仪器，与最先进的SPR仪器相比，其通量很低。我们还将了解流动池技术将如何影响表面等离子体共振（SPR）仪器的传感能力，并将开发优化的基线协议。最终结果将是48通道流动池，其将可扩展到高得多的通量（192，1536）。该流动池将是通用的，使得其将容易地与各种无标记感测技术集成。这项研究和开发工作的最终结果将是一个流动池阵列，其容量是目前最好的系统的两倍以上，并将为更高密度的系统奠定基础。这项技术的更广泛影响包括微流体流动池阵列（MFCA）的商业机会。MFCA的开发将用于与许多其他公司的生物传感平台集成。具体来说，我们将针对用于测量分子相互结合的动力学和亲和力常数的无标记技术。这是一个每年1亿美元的市场。从我们与制药公司的讨论来看，更高通量的无标签系统将导致这些技术的更大规模实施和巨大的商业潜力，包括更大的市场。即使是我们的流动池的最基本的实现也会产生实质性的影响。目前，旗舰Biacore仪器需要28小时才能处理384个样本。这些相同的384个样品使用我们的新流通池仅需要1小时。这些相同的工具将导致更快、更有效的药物发现过程，最终改善美国人口的健康状况。
