Paper-based microfluidic analytical devices(μPADs) have recently been in the spotlight for their varying applicability including point-of-care diganostics and environmental material detection. To date, was printing is the most adopted method owing to its low cost and simple procedure. However, incompatibility with some organic solvents and low thermal resistance are challenging. PDMS(polydimethylsiloxane) is the most popular polymer in microfluidics research owing to its easy fabrication, transparency, low electrical conductivity, and elasticity. To form the hydrophobic barrier using PDMA, we apply the contact printing technique using the plastic stamps. We optimize the μPAD fabrication by controlling the contacting condition including spin-coating rate and contacting time. |
