알부민 잉크의 와이핑 그라비어 인쇄적성에 관한 연구

Abstract

Recent developments of cell-based biosensors, tissue engineering to reproduce complex organ functions, and the development of transplanted cells or organ assisted external devices have continued as the development and applications of engineering structures and devices that utilize living cell functions in biology and medicine come. Neurons, which are the smallest intercellular information movement pathways in the human body, require the development of mass transfer processes between biological elements. The neurons, which are the smallest in the human body structure, are used for bio printing and bio patterning necessary for regeneration of each pattern, Research has continued. In the semiconductor market, we are confronted with limitations of technology that must make electronic components smaller than nano size. As a new growth field, we are actively converging with biotechnology. In order to manufacture nano biotechnology such as proteins and genomes, and information technologies that process large amounts of information quickly and accurately. The gravure printing method, which is widely used in the production of printed electronic parts and can be manufactured at low cost and in mass production, has been adopted for the production of bio-semiconductor devices using biotechnology. In particular, since the wiping gravure method uses an ink containing a mixture of a resin and a solvent, there is no need for tenacity and no peeling, and the application range of the printed electronic component is wide because it can be printed on paper, resin, and metal. In this study, the filling and flow of the ink into the cell was analyzed, and it was experimentally and simulated that the sagging phenomenon of the albumin ink and the change of the flow phenomenon were affected by the printing speed, pressure, ink viscosity, cell shape and depth respectively. Therefore, if the physical properties of the albumin ink and the gravure cell are determined in accordance with the printing conditions and characteristics and the shape and depth of the gravure cell are adjusted in the production of the bio semiconductor by the wiping gravure method using the albumin ink, This result can be usefully used to find the optimal printing conditions.
