Laser-direct-writing to enable filtration in paper-based devices

Laser-direct-writing to enable filtration in paper-based devices
Laser-direct-writing to enable filtration in paper-based devices
We report the use of a laser-based direct-writing technique to pattern paper-based microfluidic devices with unique fluid-filtration capabilities that enables separation of the various constituents of complex liquid sample input onto the device. For our first example we demonstrate the selective separation of differently sized Au-nanoparticles and latex microbeads from a water-based suspension using an in-line porous barrier laid across the fluid flow path. In another example we show the separation of plasma from red blood cells within whole blood using a partially-permeable flow-through filter created at the front end of the flow-channel.

Abstract

We report the use of a laser-based direct-writing technique to pattern paper-based microfluidic devices with unique fluid-filtration capabilities that enables separation of the various constituents of complex liquid sample input onto the device. For our first example we demonstrate the selective separation of differently sized Au-nanoparticles and latex microbeads from a water-based suspension using an in-line porous barrier laid across the fluid flow path. In another example we show the separation of plasma from red blood cells within whole blood using a partially-permeable flow-through filter created at the front end of the flow-channel.
