This paper describes a rapid fabrication process in vertical poly dimethylsiloxane (PDMS) fluidic device for bio-applications by Rapid Prototyping (RP). Rapid Prototyping is fast, easy and mask-less process to build the 3-dimension structures. The process allows for the stacking of many PDMS channel layers to realize vertical fluidic device. In this paper, the vertical PDMS fluidic device is consisted two PDMS fluidic channel layer included top fluidic channel layer and bottom fluidic channel layer. The fluidic channel structures is manufactured by Rapid Prototyping then glued on a glass substrate with UV curing as a master. The Teflon-like film is coated on the surface of master. The PDMS is cast against the master producing molded channel layer. After curing process, the PDMS replica is easily peeled off from the master. The top and bottom fluidic channel layers are aligned and bonded together by oxygen treatment to form vertical fluidic device. The performance of vertical fluidic device prepared using this rapid prototyping technique has been demonstrated by fabricating a miniaturized bio-application system.
