WHAT ACADEMICS & PROFESSIONALS ARE SAYING

The MiiCraft provides a good compromise among price, resolution, size and ability to make transparent microchips in the visible spectrum, with devices showing acceptable transmittance above 430 nm. The print time of simple microfluidic devices can be as low as 12 min with a material cost of $1 per device, making this an attractive approach for rapid prototyping. While this may seem trivial for laboratories with substantial funds, it will expand the scope of microfluidics to be readily available to researchers on a limited budget. A complex 3D microfluidic structure was developed for continuous nitrate analysis. The device comprised three fluidic layers (sample, reagent, and standard addition of nitrite), micromixers, and a series of detection cells with depths increasing from 0.5 to 15 mm to increase the linear range of the colorimetric assay. This complex microdevice was printed in <5 h and was used to determine the level of nitrate in tap water, with levels agreeing with values determined using an off-chip assay. The low cost of the printer and the simplicity with which complex 3D microfluidic devices operate offer great potential for improved development of microfluidic applications. [1] [2]
