Epoxy resin mold and PDMS microfluidic devices through photopolymer flexographic printing plate

Hybrid microchannel-solid state micropore device for fast and optical cell detection

“…Then, an epoxy resin mold (ERmold) was manufactured. 40 The photopolymer Flexcel NX and Thermal Imaging Layer (TIL) used in the mold fabrication were supplied by Eastman Kodak. Furthermore, the epoxy resin and curing agent were supplied by Cristal-Tack, Novarchem -Argentina.…”

“…2a). The PDMS was mixed with curing agent in a 10 : 1 weight ratio (Sylgard 184 Silicone Elastomer Kit), as previously described by Olmos et al 40 Then, the mixture was placed under vacuum for 30 min to remove air bubbles, poured onto the ERmold and cured in an oven at 40 C overnight.…”

Recent Progress of Microfluidic Devices for Hemodialysis

“…However, these materials are brittle and expensive, so they often meet constraints in practical applications. To address these limitations, a large variety of alternative polymer materials, such as thermoplastic polymers (PMMA, PC, polyethylene), solidified polymers (PDMS, epoxy resin, PU) and solvent volatile polymers, have been explored for the large‐scale fabrication of microfluidic devices due to their diversity, ease of processing and molding, low cost.…”

Cost-effective fabrication of photopolymer molds with multi-level microstructures for PDMS microfluidic device manufacture

“…18,20,28,29 Recently, we reported the manufacture of PDMS microuidic devices by employing a exographic photopolymer as mold. 30,31 Advantages related to resolution, mold size, aspect ratio, roughness, availability, scalability and costs were demonstrated. 30 It is possible to obtain minimum channel widths lower than non-traditional techniques such as CO 2 laser ablation, 32 building blocks, 33 laser ablation, 34 laser swelling, 35 semicontact writing, 36 3D printing, 37,38 WAX mold.…”
