For example, the aquaporin protein - mediated flow of water across biological cell membranes is down to a balance between hydrophobic and hydrophilic interactions with channel surfaces.

The researchers believe that in hydrophilic materials, the attraction for water — a property known as «wettability» — makes water molecules more difficult to move, contributing to an increase in the fluid's effective viscosity.

Freshly emitted soot is an example of a hydrophobic aerosol type; after chemical transformation in the atmosphere (e.g. oxidation of its surface rendering it more hygroscopic; condensation of more hydrophilic species onto the particle) it will gradually pick up water as well.

Meanwhile, the polymers, which exist in a watery solution, can carry hydrophilic molecules such as proteins, including antibodies and growth factors.

While silica does not participate directly in the catalysis, the surface molecular composition of the silica grains can influence its effectiveness if the chemical group is predominantly hydrophilic or hydrophobic.

The researchers found that if the silica tends to have hydrophilic silanol groups on its surface, it attracts water molecules, in effect forming a «soft barrier» of water molecules that reactants would have to overcome to somehow penetrate to proceed with the desired process or reaction.

There are two different types of chemical groups that comprise glass surfaces, he said: silanol (SiOH) groups that are generally hydrophilic (water - loving), or siloxane (SiOHSi) groups that are typically water - repellant.

When the two regions make contact, they coalesce, and the tension between hydrophobic and hydrophilic regions creates a force that carries the entire spore into the air.
