Micro devices have become a considerable part of our daily life and are embedded in a multitude of technologies such as inkjet printers, air bags, and smart phones. A further upcoming micro technology is the Lab-on-Chip (LOC) with its immense promise in the healthcare field. A LOC integrates several biological or chemical laboratory functions on a single chip less than a few centimetres in size. A typical application could be the determination of blood's insulin content of a diabetic person. The LOC concept features several advantages such as reduced fabrication and maintenance costs, improved performance, and also less waste. A distinguished feature of micro devices is that several physicochemical phenomena become prominent which are unimportant in large scale devices. These phenomena can be favourably employed to design micro pumps for LOCs. To make crucial breakthroughs for this micro technology it should be possible to utilize any desired liquid within such devices. The requested equipment described in this application will allow for the characterization of very small particles. This is essential to the development of LOCs relying on pumping of non-polar liquids such as oil or turpentine. The knowledge generated will directly be adopted in the development of LOCs for medical applications. Development of such micro devices for rapid, portable medical diagnostics will directly benefit to the Canadian healthcare system by providing patients an affordable, easy access to regular testing that can be carried out in privacy at home. The equipment will also be employed by co-applicants to improve the technology of fuel cells; devices that convert a fuel directly into electrical energy. Fuel Cells have considerable higher efficiencies than conventional systems based on fuel combustion and, hence, are considered green and sustainable technologies. The development of such technologies directly benefits the Canadian economy both through internal consumption and export of high-tech products. Also, the research will assist in the expansion of `high tech' jobs in Canada through the training of highly qualified engineers and scientists and encourage companies to move to or start-up in Canada.

微型设备已成为我们日常生活的相当一部分，并嵌入了许多技术，例如喷墨打印机，安全气囊和智能手机。即将到来的微技术是实验室片（LOC），其在医疗保健领域的巨大承诺。一个LOC在单个芯片上集成了几个生物学或化学实验室功能，小于几厘米的大小。典型的应用可能是确定糖尿病患者血液的胰岛素含量。 LOC概念具有多种优势，例如降低制造和维护成本，提高性能以及浪费较少。微型设备的一个杰出特征是，几种物理化学现象变得突出，在大型设备中并不重要。这些现象可用于设计LOC的微泵。为了使这项微技术取得关键的突破，应该可以在此类设备中利用任何所需的液体。本应用中描述的请求的设备将允许表征非常小的颗粒。这对于依靠泵送非极性液体（例如石油或松节油）的LOC的发展至关重要。生成的知识将直接用于医疗应用的LOCS开发。开发此类微型设备以快速，便携式医疗诊断将直接从加拿大医疗保健系统中受益，从而为患者提供负担得起的，易于访问常规测试，可以在家中进行隐私。该设备还将由共同陈列机来改善燃料电池技术。将燃料直接转换为电能的设备。燃料电池的效率比基于燃料燃烧的常规系统高得多，因此被认为是绿色和可持续的技术。这种技术的开发直接通过内部消费和出口高科技产品而受益于加拿大经济。此外，这项研究将通过培训高素质的工程师和科学家的培训来帮助扩大加拿大的“高科技工作”工作，并鼓励公司搬到加拿大或启动加拿大。
