Organic and Printed Electronics for Biological Microfluidic Applications

A Printed Circuit Board Based Microfluidic System for Point-of-care Diagnostics Applications

We propose an alternative approach for fabricating microfluidic devices by using printed circuit board (PCB) as a substrate to produce high precision, highly integrated microfluidic systems. Driven by consumer electronics industry, the PCB manufacturing has reached a high level of maturity and precision, enabling the production of sophisticated electronic substrates at high-resolution and low c...

Chemically Robust, Rapidly Printed Polyurethane Microreactor for Synthesis of Monodispersed Magnetic Iron Oxide Nanoparticles

This paper introduces a novel fabless, polyurethane microfluidic reactor (PMR) for the production of magnetic nanoparticles using droplet-based flow. The PMR system is the most chemically robust polymer platform to date for nanoparticle synthesis; unlike other polymeric microfluidic platforms such as polydimethylsiloxane (PDMS), it does not absorb aqueous solvents, alcohols or organic materials...

Low-cost Flexible All-inkjet-printed Microfluidic Sensor

This paper demonstrates a novel and low-cost additive manufacturing process for flexible and disposable microfluidics on virtually any substrate, with which the first “all-inkjet-printed” microfluidic microwave sensor is prototyped. A 30-μm-high 600-μm-wide SU-8 (polymer) 3-D microfluidic channel and an electromagnetic sensing setting are fabricated with sole reliance on multilayer inkjet-print...

The OE-A roadmap for organic and printed electronics: creating a guidepost to complex interlinked technologies, applications and markets

Coplanar Digital Microfluidics Using Standard Printed Circuit Board Processes

We report three novel demonstrations: 1. Coplanar electrowetting 2. Electrowetting on a printed circuit board (PCB) and 3. Transport and mixing in an “open” microfluidic substrate. Similar to “soft” lithography which enabled many researchers to easily prototype and experiment with continuous-flow microfluidics, this work allows researchers to easily experiment with discrete-flow microfluidics (...
