The purpose of this study is to produce tiny gel particles of natural polymeric material as a model blood cell by using an electro-hydrodynamic (EHD) spraying. The EHD spraying involves various modes, and our attention was focused on a cone-jet mode, which produced minute and homogeneous droplets. A model blood cell for use in the experiment in vitro to simulate human circulation was made by chemical reaction between sodium alginate solution and calcium chloride solution. In this study, we tried to react between the droplets which are sprayed by the cone-jet mode of the sodium alginate solution and the droplets of the calcium chloride solution which are sprayed by ultrasound type nebulizer or injection nozzle. As a result, we got many minute and homogeneous gel particles and many pieces of aggregation composed of a lot of minute gel particles.
