Multifunctional reversibly sealable microfluidic devices for patterned material deposition approaches

摘要: We present a concept to produce reversibly sealable polydimethylsiloxane (PDMS) based microfluidic devices with versatile channel designs, withstanding pressures up 600 kPa. A novel fabrication strategy, namely the casting of secondary PDMS casing around initial system allows diverting tubing attached channels sideways so that simple mounting assembly can be used press fluidic chip onto virtually any type substrate. demonstrate functionalities developed setup at proof-of-concept level by direct printing electronic interconnects flexible substrates in single step. As second application, we generate uniquely shaped polymer structures when combining presented technique droplet microfluidics using UV-curable adhesive and water as continuous dispersed phases, respectively. believe approach has plethora applications clear perspective being for cost-efficient multifunctional designs classes materials diverse areas from electronics biotechnology.
