Laboratory-on-a-chip (LoC) technology is poised to improve global health through development of low-cost, automated point-of-care testing devices. In countries with few healthcare resources, clinics often have drugs to treat an illness, but lack diagnostic tools to identify patients who need them. To enable low-cost diagnostics with minimal laboratory support, this project will investigate domain-specific LoC programming language and compiler design in conjunction with device fabrication technologies (process flows, sensor integration, etc.). The project will culminate by building a working LoC that controls fluid motion through electronic signals supplied by a host PC; a forensic toxicology immunoassay will be programmed in software and executed on the device. This experiment will demonstrate benefits of programmable LoC technology including miniaturization (reduced reagent consumption), automation (reduced costs and uncertainties associated with human interaction), and general-purpose software-programmability (the device can execute a wide variety of biochemical reactions, all specified in software). Information necessary to reproduce the device, along with all software artifacts developed through this research effort, will be publicly disseminated. This will promote widespread usage of software-programmable LoC technology among researchers in the biological sciences, along with public and industrial sectors including healthcare and public health, biotechnology, water supply management, environmental toxicity monitoring, and many others.This project designs and implements a software-programmable cyber-physical laboratory-on-a-chip (LoC) that can execute a wide variety of biological protocols. By integrating sensors during fabrication, the LoC obtains the capability to send feedback in real-time to the PC controller, which can then make intelligent decisions regarding which biological operations to execute next. To bring this innovative and transformative platform to fruition, the project tackles several formidable research challenges: (1) cyber-physical LoC programming models and compiler design; (2) LoC fabrication, including process flows and cyber-physical sensor integration; and (3) LoC applications that rely on cyber-physical sensory feedback and real-time decision-making. By constructing a working prototype LoC, and programming a representative feedback-driven forensic toxicology immunoassay, the project demonstrates that the proposed system can automatically execute biochemical reactions that require a closed feedback loop. Expected broader impacts of the proposed work include reduced cost and increased reliability of clinical diagnostics, engagement with U.S. companies that use LoC technology, training of graduate and undergraduate students, increased engagement and retention efforts targeting women and underrepresented minorities, student-facilitated peer-instruction at UC Riverside, a summer residential program for underrepresented minority high-school students at the University of Tennessee, collaborations with researchers at the Oak Ridge National Laboratory, and creation, presentation, and dissemination of tutorial materials to promote the adoption and use of software-programmable LoCs among the wider scientific community.

芯片实验室 ​​(LoC) 技术有望通过开发低成本、自动化的即时检测设备来改善全球健康。在医疗资源匮乏的国家，诊所通常有治疗疾病的药物，但缺乏诊断工具来识别需要这些药物的患者。为了以最少的实验室支持实现低成本诊断，该项目将研究特定领域的 LoC 编程语言和编译器设计以及设备制造技术（工艺流程、传感器集成等）。该项目将通过构建一个工作 LoC 来达到顶峰，该 LoC 通过主机提供的电子信号控制流体运动；法医毒理学免疫测定将在软件中编程并在设备上执行。该实验将展示可编程 LoC 技术的优势，包括小型化（减少试剂消耗）、自动化（降低成本和与人类交互相关的不确定性）和通用软件可编程性（该设备可以执行各种生化反应，所有这些都在软件中指定）。复制该设备所需的信息以及通过这项研究工作开发的所有软件工件将被公开传播。这将促进软件可编程 LoC 技术在生物科学研究人员以及公共和工业部门（包括医疗保健和公共卫生、生物技术、供水管理、环境毒性监测等）中的广泛使用。该项目设计并实现了一个软件可编程网络物理片上实验室 (LoC)，它可以执行各种生物协议。通过在制造过程中集成传感器，LoC 能够向 PC 控制器实时发送反馈，然后 PC 控制器可以就下一步执行哪些生物操作做出智能决策。为了使这个创新和变革的平台取得成果，该项目解决了几个艰巨的研究挑战：（1）网络物理LoC编程模型和编译器设计； (2) LoC制造，包括工艺流程和信息物理传感器集成； (3) 依赖网络物理感知反馈和实时决策的LoC应用。通过构建工作原型 LoC，并对代表性的反馈驱动法医毒理学免疫测定进行编程，该项目证明所提出的系统可以自动执行需要闭合反馈环路的生化反应。拟议工作的预期更广泛影响包括降低成本和提高临床诊断的可靠性、与使用 LoC 技术的美国公司合作、培训研究生和本科生、增加针对女性和代表性不足的少数族裔的参与和保留工作、加州大学河滨分校由学生推动的同伴指导、田纳西大学针对代表性不足的少数族裔高中生的暑期住宿项目、与 橡树岭国家实验室的研究人员，以及教程材料的创建、演示和传播，以促进软件可编程 LoC 在更广泛的科学界中的采用和使用。
