将微流控和片上实验设备结合起来，实现自动化和增强控制
芯片上的实验室被称为用于控制和操纵微观水平的流体流动的装置和方法。已知这些微流体装置操纵和控制在多个领域使用的装置中的流体。在典型的基本系统中，至少需要两种不同的压力源（Badawy，2010）。一个涉及主要需要大于10psi的压力水平的片上阀的致动。另一种已知是在微流体通道内驱动试剂。在传统意义上，通过使用与压缩气体罐相连的两个压力调节器来实现这一点。然而，所有组件的性质和大小已知使得它们对于可以手持的系统的建立而言是不稳定的（Bruus，2008）。尽管有可能使用两个小型化的隔膜泵来建立这样的系统，但与隔膜泵上的输出压力相关的相当大的波动有助于限制应用。为了实现自动化和增强控制，微流体液体的手持搬运系统已经发展。这个系统有助于提供两种不同的压力来源，以及一系列的气动控制线，用于片上系统的操作（Chen，2011）。其中一个压力来源是设置更多的10psi，最大水平为20psi，用于芯片上弹性阀的操作，而另一个被认为设置在5psi以下以驱动液体流动。

Combining Microfluidic and Lab- on- a- Chip Devices for automation and enhanced control
Lab on a chip is referred to as the device and method used to control and manipulates the flows of fluid at the levels of micro. These devices of microfluidic are known to manipulate and control the fluids in devices used across a number of fields. In a typical and basic system, a minimum of two different sources of pressure are required (Badawy, 2010). One is related to the actuation of on- chip valves that mainly need level of pressure that is more than 10 psi. The other is known to be driving reagents within the channels of microfluidic. In the traditional sense, the achievement of this is done by the use of two regulators of pressure that are in connection with the tank of compressed gas. However, the nature as well as sizes for all of components is known to be making them unstable for the establishment of system that can be handheld (Bruus, 2008). Even though there is a possibility for using two pumps of miniaturized diaphragm for the establishment of such a system, the considerable fluctuations related to the output pressure over a pump of diaphragm helps in limiting the application. For the enabling of automation and enhanced control, there has been development of handheld handling system for the microfluidic liquid. This system helps in providing two different sources of pressure along with an array of eight lines of pneumatic control for the operation of lab- on- a- chip system (Chen, 2011). One of the sources of pressure is set more the 10 psi with the maximum level of 20 psi for the operation of elastomeric valves on chip, while the other is known to be set below 5 psi for driving the flow of liquid.
