Researcher invents an easy-to-use technique to measure the
hydrophobicity of micro- and nanoparticle

The scientific and industrial communities who work
with micro- and nanoparticles continue to labor with the challenge
of effective particle dispersion. Most particles that disperse in
liquids aggregate rapidly, and eventually precipitate, thereby
separating from the liquid phase. While it is commonly accepted
that the hydrophobicity of particles— how quickly water repels off
a surface—determines their dispersion and aggregation potential,
there has been no easy-to-use method to quantitatively determine
the hydrophobicity of these tiny particles.
