-phoresis explained

The suffix -phoresis means "migration":

• Phoresis, where one organism attaches itself to another for travel.
• Diffusiophoresis, motion observed in liquid environments where chemical gradients are generated by contact between solutions with different solute concentrations
• Electrophoresis, motion of dispersed particles relative to a fluid under the influence of a spatially uniform electric field
• Isotachophoresis, technique in analytical chemistry used to separate charged particles
• Necrophoresis, disposal of bodies of dead members of their colony in social insects
• Thermophoresis, phenomenon observed when a mixture of two or more types of motile particles (particles able to move) is subjected to the force of a temperature gradient and the different types of particles respond to it differently
