Droplet Microarrays are transparent and planar arrays on glass slides of a unique, patented surface coating technology from Aquarray that enables the formation of defined and separated droplets on a liquid-repellent background.


Aqueous solutions are trapped in these 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 10 nl.

Carriers

Standard-Glass-Slide "G"

This substrate is used for standard chemical and biological work.


ITO-Glass-Slide "I"

Conductive and IR-reflective properties of the additional indium tin oxide (ITO) coating make AQUARRAY‘s Droplet Microarray compatible with applications such as on-chip MALDI-TOF mass spectrometry or IR spectroscopy.

 

Coatings

Type "np"

A surface compatible with aqueous media. This coating is ideal for cell culture applications. The static water contact angle of the superhydrophobic borders have a value of > 158°. The hydrophilic areas have a static water contact angle of < 10°.


Type "dd"

A surface compatible with both aqueous and organic solutions. The static water contact angle of the omniphobic borders have a value of > 108°. The omniphilic areas have a static water contact angle of < 40°.
