| Summary: | Currently, new fabrication methods for rapid prototyping of microfluidic devices has bring attention among
researchers from various fields. The main reason is the use of lithographic equipment in standard fabrication method
for master fabrication require trained personnel and high cost disposable materials. In this paper, a new fabrication
method via printed conductive silver ink is introduced in order to minimize the current fabrication process through
elimination of the photolithography process. As a result, a usable, faster and cost effective prototyping process of a
microfluidic based biosensor devices able to be produced. In this method, the conductive silver ink was used to
create a master template contains microchannel onto glass-reinforced epoxy laminate sheets (FR-4). Then,
Polydimethylsiloxane (PDMS) were used to replicate the structure. Next, the digital microscope was used to obtain
images to demonstrate geometry fluidics structure with channel dimension up to 200 µm width. Moreover, a 3D
profilometer was used to evaluate their thickness and roughness of the microfluidics structure. The stability test
demonstrates the consistency of flow sequence inside the serpentine and separation channel. |
