3-dimensional paper-based fluidic devices using parafilm-infused paper

초록

Here, we have presented novel paper-based fluidic devices (PFDs) that can provide cheap systems in fluid manipulation for a variety of applications including medical diagnosis, environmental monitoring and food quality testing. One example of PFDs is a 3D time-gated flow device fabricated by using parafilm-based papers. In this device, an aqueous sample was divided into four branches, and then reached detection zones at different arrival times with passing through grid-patterned paper acting as a time-delay layer. Second PFD is a 2D lateral flow device possible to deliver multiple reagents to a detection zone, sequentially. Furthermore, we have also demonstrated a multiplexing colorimetric sensor chip with a new PFD channel structure based on hollow paper, providing a spontaneous and very fast flow rate. ? 15CBMS-0001.
