项目摘要

Objective: The objective of this project is to investigate a tunable wetting mechanism on a smart polymer - dodecylbenzenesulfonate-doped polypyrrole (PPy(DBS)) - for manipulating liquid droplets at ultra-low-voltages (~1.5V). Intellectual Merit: This research will address fundamentals of wetting mechanism on a smart polymer surface, which are not well understood for microfluidic applications. In particular, this experimental study will provide insights to what extent Marangoni stress contributes to the overall droplet behavior, facilitating better understanding of inter-relationship between surface wetting and droplet manipulation. Further, this project will enable the development of lab-on-a-chip devices which can bi-directionally transport liquid droplets, but at orders of magnitude lower voltages than existing techniques. Broader Impact: Successful research on this tunable wetting concept will impact a wide range of microfluidics applications including on-chip sample preparation and handling, and lab-on-a-chip devices manipulating complex biological fluids, attributed to the low-voltage operation. In particular, it will enhance portability and in-field operation of digital microfluidic devices, since the system can be operated using standard batteries. In addition, this research will serve as the basis for educational initiatives with a special emphasis on recruiting and mentoring students from under-represented minorities, while forging institutional affiliations with organizations such as the Women in Engineering Program and Advocates Network, the National Action Council for Minorities in Engineering, and Alliances for Graduate Education and the Professoriate. Furthermore, the program will work with the Center for Innovation in Science and Engineering Education at Stevens to extend this effort to K-12 outreach endeavors.
目的:本项目的目的是研究智能聚合物-十二烷基苯磺酸盐掺杂的聚吡咯(PPy(DBS))-在超低电压(~1.5V)下操纵液滴的可调润湿机制。智力优势:这项研究将解决智能聚合物表面上的润湿机制的基本原理,这是没有很好地理解微流体应用。特别是,这项实验研究将提供深入了解在何种程度上Marangoni应力有助于整体液滴的行为,促进更好地了解表面润湿和液滴操作之间的相互关系。此外,该项目将使芯片实验室设备的开发成为可能,该设备可以双向传输液滴,但电压比现有技术低几个数量级。更广泛的影响:对这种可调润湿概念的成功研究将影响广泛的微流体应用,包括芯片上样品制备和处理,以及由于低电压操作而操纵复杂生物流体的芯片实验室设备。特别是,它将增强数字微流体设备的便携性和现场操作,因为该系统可以使用标准电池进行操作。此外,这项研究将作为教育举措的基础,特别强调招收和辅导来自代表性不足的少数群体的学生,同时与妇女工程方案和倡导者网络、工程少数群体国家行动理事会以及研究生教育联盟和教授协会等组织建立机构联系。此外,该计划将与史蒂文斯科学与工程教育创新中心合作,将这一努力扩展到K-12外展工作。
