| Summary: | 碩士 === 國立屏東科技大學 === 生物機電工程系所 === 97 === Dielectrophoretic biochip can manipulate biological cell and bacteria. Be used in dairy products rapid detection of bacteria. This thesis is intended to match dielectrophoretic biochip , developing a platform for rapid detection apply in ranch. On research use a microscope for the observation biochip and positioning system(stepper motor). Instrument the development of design and test. Microscope test: objective lens selected , objective lens work distance , objective lens resolution. Employ Zemax simulation of optical software. Simulation number aperture of objective and relationship between light intensity. Employ TracePro simulation of optical software, simulation sample is dielectrophoretic biochip, the impact of light intensity and the ray-tracing. Stepper motor positioning system for performance analysis: resolution , max speed , positioning accuracy , and location reproducibility.
