PI's Name, Institution: Zonglu Susan Hua, SUNY-BuffaloProposal Number: 0201293Proposal Title: A Novel Mechanism to Make Microfluidic Components and Systems Requiring No Mechanical Moving PartsProject Abstract: The research is focused on developing a novel mechanism for actuation that would enable fabrication of various microfluidic components that require no moving mechanical parts. The novel actuation mechanism is based on electrochemistry to generate bubbles, which acts as control elements of a microfluidic system. This method is intrinsically low power in nature, requires a simple on-chip electronics circuitry, and the control elements are self-repairing. Detailed studies are being performed on making valves, pumps, switches, and fluid logic system. The experimental studies are being complemented with fundamental investigation of bubble formation, including bubble nucleation and collapse as a function of pressure, applied voltage, flow rate, and interface conditions between the bubble and microchannel walls. These studies are of fundamental as well as technological interest in fields ranging from microbiology, biotechnology, and drug delivery, to combinatorial and analytical chemistry. The educational, training, and outreach includes hands-on experience by graduate as well as undergraduate students, along with specific high school summer program targeted at women and minorities. It is providing students with important training in areas such as microfabrication technology, thin film growth, metrology, device fabrication, testing, and characterization.

主要研究者姓名，机构：Zonglu Susan Hua，SUNY-Buffalo提案编号：0201293提案标题：一种新的机制，使微流控组件和系统不需要机械移动部件项目摘要：该研究的重点是开发一种新的驱动机制，使各种微流控组件的制造不需要移动机械部件。 新型驱动机制是基于电化学产生气泡，作为微流体系统的控制元件。 这种方法本质上是低功率的，需要简单的片上电子电路，并且控制元件是自修复的。正在对阀门、泵、开关和流体逻辑系统的制造进行详细的研究。实验研究正在补充与气泡形成的基础研究，包括气泡成核和崩溃的压力，施加电压，流速和气泡和微通道壁之间的界面条件的函数。这些研究在微生物学、生物技术、药物输送、组合化学和分析化学等领域具有基础和技术意义。教育、培训和推广活动包括研究生和本科生的实践经验，沿着针对妇女和少数民族的具体高中暑期课程。它为学生提供了重要的培训领域，如微加工技术，薄膜生长，计量，设备制造，测试和表征。
