Abstract

This paper describes a simple fabrication method of 3 D micro container using PDMS (polydimethylsiloxane) stencil by solvent evaporation. PDMS stencils were prepared by air knife system designed by our group. PLGA (poly (lactic-co-glycolic acid)), which is a bio polymer, was used as material of micro container. The size and geometry of micro container were easily controlled by that of PDMS stencil. The fabricated micro container could be sealed with aqueous alginate solution. Furthermore, feasibility of fabricated micro container as a cell container was inspected by culturing HepG2 (liver hepatocellular carcinoma) cell.
