Abstract: Microfluidic paper-based analytical devices (MPADs) are simple, low-cost, and portable measurement devices, which reduce sample and reagent consumption. A biodegradable polymer, polylactic acid (PLA) was employed to create hydrophobic patterns for fluidic channels using a 3D fused deposition model (FDM) printer. The 3D printed PLA circular channel with 10 mm in diameter and 0.6 mm in height was deposited onto Whatman no. 1 filter paper using heat and solvent. The effects of heating temperature, heating time, organic solvent type, and organic solvent volume on channel deposition to create 3D barriers on filter paper were examined. Under the optimized conditions, the reproducibility of the uPADs production was examined by measuring the ㆍRSD of the obtained diameters of circular zones. The developed PLA-uPAD will be further investigated to demonstrate the applicability of the devices for various colorimetric analyses.
