To cover a mold with gold, I tried 2 different gold plating methods, medical gold plating and bio-compatibility gold plating. Cells cannot attach on medical plating but can attach on bio-compatibility plating. Cells can also be detached on bio-compatibility plating by using electrochemical cell detachment. After I made bunny model as mold for cell sheet by using streolithography which can make different 3D models, I covered this mold with gold by using bio-compatibility gold plating. I could attach cells on bunny model. This method will be useful for tissue engineering.
