We present an active fixed-volume mixer based on the creation of multiple source–sink microfluidic flows in a polydimethylsiloxane (PDMS) chip without the need of external or internal pumps. To do so, four different pressure-controlled actuation chambers a ...

We present the rapid fabrication of custom protein micro-arrays, in less than 35 minutes, on the surface of immobilized beads using microchannel-guided flows driven by a single syringe pump. The commercially available beads provide robust micro-array surfa ...

We present a microfluidic device for on-chip analysis of low-concentration protein biomarkers. A new detection method, based on the magnetic capture of proteins via superparamagnetic beads and counting the surface coverage of the latter is presented. The p ...

We present an active mixer based on the creation of virtual source-sink pairs in a polydimethylsiloxane (PDMS) chip. Perfect mixing is achieved in only a sub-second time interval for a compact 5 μL mixing volume. This excellent performance is achieved than ...
