In changing the nozzle angle of the micro-electrospray chip can become a research of electrospray. The traditional spectrum was using stainless tube to be the injector. This study uses the micro fabrication technology to fabricate the chip for experiment. The micro fabrication technology can integrate the experiment system on a chip. In the developing of biochip, they used to integrate electrophoresis and electrospray to detect the unknown protein. The thesis is trying to study the electrospray. 　　This study in using microscope-flow-visual-system to find out the optimum operation model in different combination of voltage and current. Different nozzle angle has different cone-jet mode. Smaller nozzle angle needs only smaller voltage. And bigger nozzle angle needs bigger voltage. This study use chemical treating to make surface changing in order to decrease the wetting area and also decrease the spray size. In the end of this thesis, the principle of the dimensionless factors published from the literature review have been proved by the results of this experiment.
