KurzfassungA Swedish research institute has developed a technology for printing microfluidic valves on substrates like paper or plastic foils. The technology utilizes novel printing inks in conventional printing equipment, in order to achieve low cost fluid flow control systems. It is applicable in areas such as disposable microfluidic platforms and highly functional microfluidic chips.
The institute is looking for all kinds of collaboration agreements with partners within microfluidics and diagnostics.
In this technology, the valve is based on a surface consisting of a printable polymer with switchable wetting properties. A fluid entering the microfluidic system is drawn in by capillary forces and stops at the valve surface. When the valve is activated, the surface switches from hydrophobic to hydrophilic and the fluid is able to pass the valve. The activation is induced by applying a voltage, typically below 3V.
A slightly modified printing press is used to manufacture the valve in as few as two steps. The valve is printed on a substrate, which is coupled with a microfluidic structure made out of injection molded plastics. These two constitute the microfluidic system with built-in electronic flow control.
The research institute is looking for possible collaboration partners within the areas of microfluidics and diagnostics, from industrial as well as academic research groups.
At present, inkjet printing is used, but efforts are put in to developing screen printing and reel-to-reel printing processes. With reel-to-reel printing the printing speed has the potential to reach up to 100 m/min. With this manufacturing process, production and assembly can be automated at very high speeds, resulting in cost reductions of between 10-100 times. Systems produced may be both environmentally friendly and fully disposable.
The valve function has been verified in proof of principle experiments, conducted with various fluids, including aqueous electrolytes, blood plasma, urine and saliva.
