Answer» Correct Answer - Option 4 : Substances that prefer to dissolve in water type fluids Explanation: Hydrophilicity Hydrophilicity is a critical feature in fluid flow mechanisms used for microfluidic devices. The resistance to fluid flow is especially important in a passive flow device where capillary action is used to move fluid such as test strips. Hydrophilic surfaces are “water-loving”, in that they allow fluids to wet out or flow across a surface and promote fluid flow through a channel into a test chamber. The surface energy or degree of hydrophilicity varies widely in device construction materials from water-repelling or hydrophobic (low surface energy) to hydrophilic (high surface energy) where water easily wets a surface.

Answer» Correct Answer - Option 4 : Substances that prefer to dissolve in water type fluids

Explanation:

Hydrophilicity

Hydrophilicity is a critical feature in fluid flow mechanisms used for microfluidic devices.
The resistance to fluid flow is especially important in a passive flow device where capillary action is used to move fluid such as test strips.
Hydrophilic surfaces are “water-loving”, in that they allow fluids to wet out or flow across a surface and promote fluid flow through a channel into a test chamber.
The surface energy or degree of hydrophilicity varies widely in device construction materials from water-repelling or hydrophobic (low surface energy) to hydrophilic (high surface energy) where water easily wets a surface.
