抄録

In this study, we devised a method of printing gellan gum solution and forming gellan gum gel using electrostatic inkjet method. Electrostatic ink jet is capable of printing highly viscous liquid with high resolution because liquid is ejected from the tip of the nozzle by electrostatic force, so that liquid smaller than the nozzle tip is ejected. Gellan gum is a polysaccharide and gellan gum solution turns into gels when it reacts cations contained in the culture solution. Therefore, it is low in toxicity. In addition, gellan gum gels are capable of cell culture thereby modifying the cell adhesion factor. From this fact, it was thought that it is possible to fabricate precise gellan gum gel biodevice. From the characteristics of gellan gum, it is possible to fabricate a gel having a unique shape by printing gellan gum solution of using an electrostatic ink jet. In this research, we investigated its characteristics and report it.
