Outline of Final Research Achievements

In this project, the new method that is composed of thin glass pipette and tungsten needle has been propsed so that micro capsules with the size less than 100 micro meter in diameter. In this mechanism, the thin needle can push out the small amount of the high viscous liquid in the tube to the target surface. Then the liquid at the tip end can be transfered on the target surface and it can be capsule in another liquid.In the experiments, the conditions such as the tube diameter and the viscosity were surveyed to get the appropriate size of the capsule and droplet. This simple mechanism is unique so that it can provide the small amount of the high viscous liquid with 50,000mPas with high repeatability.
