Multifunctional Microfluidic Chip Test And Control System Design And Build

Micro-fluidic Electrophoresis Chip is a rapidly developing field in recent years. The micro-channel network on the chip is manufactured by the technology of Micro Electro Mechanical System (MEMS) on the substrate of glass, fused silica, PDMS etc. Sample separation is performed in the micro-channel and detected by optical or chemical methods. Based on Capillary Electrophoresis(CE), MFE chip is a multidisciplinary technology, which has roots in Micro Optical Electro Mechanical System, biochemistry and analytical chemistry. It became a new platform in the field of analytical chemistry, especially in the life science, drug discovery and medicine.Micro-fluidic Chip is the important set of μTAS, whose performance will much influence the result of μTAS experiment. But now the method of detecting chip is of no good effect, and we can't find certain special equipments with which we can detect the parameter of Micro-Chip, such as velocity, temperature. It can't meet the requirement of Micro-Chip developing.So, The topics of this dissertation is researching and developing a new and special detecting system platform. The system can accurately control and drive the micro- liquid, and has a steady working environment.1. Designing the main controlling board, which has micro-liquid controlling module, PID temperature controlling module2. Using the 12bits A/D circuit to get the data, and quickly data processing and analyzing3. To build the whole System, do some experiment to validate the systemThe major work is building system, programming the software of system and analyzing the quality of Micro-Chip.
