Guided liquid flow in a glass microfluidic channel
Surfix and the HEIDENHAIN Group demonstrate guided liquid flow in a glass microfluidic channel by a patterned hydrophobic nanocoating.
The fast and simple nanocoating process offers a scalable route towards manufacturing advanced glass microfluidic devices. Application examples include the generation of double emulsions in a single chip, fabrication of phase guides, and stop-and-go structures.
The video (link below) shows an aqueous dye solution flowing through a glass microfluidic channel (courtesy of the HEIDENHAIN Group) with Surfix’s patterned hydrophobic nanocoating. The liquid is confined to the non-coated hydrophilic areas and spontaneously follows the flow path defined by the nanocoating.
