A glass surface is hydrophilic, meaning it attracts water. This is often an advantage when working with glass microfluidic chips, but in certain applications you would need the surface to be hydrophobic or modified with a coating that prevents adsorption of small molecules.

In drug development, for instance, compounds can be screened using microfluidic chips. In order to prevent compounds to stick to the walls, a coating should be applied to the channel walls.

By using a proprietary surface treatment method to create ultra thin layers, Micronit can modify the glass surface in the channels, for instance creating anti-stiction or hydrophobic surfaces and channel walls. This improves the reliability of the experiments.
