An Innovative Approach
AQUARRAY's innovative DMA-technology is based on a patterning process that uses high-performance nanomaterials to create planar arrays of wettable (hydrophilic or omniphilic) spots separated by a non-wettable (superhydrophobic or omniphobic) grid on transparent glass.
Aqueous solutions are trapped in the hydrophilic spots due to the extremely high surface tension. The droplets formed remain stably suspended even when the DMA is shaken or turned upside down. The technology allows the production of a wide range of patterns resulting in a range of 80 to 6048 spots per DMA and working volumes from 5000 nl down to 20 nl.
The patterning process can also be performed on alternative materials such as steel or ITO coated substrates, and can be adapted for use with low surface tension fluids such as mild organic solvents. This further extends the range of applications.
