Tensions at liquid interfaces: a general filter for the separation of micro-/nanoparticles.
In this letter, we put forward a new strategy for the separation of micro-/nanoparticles with different sizes and densities by using the tensions at liquid interfaces. The interactions between particles and a liquid-liquid interface have been analyzed. Furthermore, we applied our strategy to the separation of two size-distributed Cu2O particles by using the water and n-pentanol interface, which demonstrates the feasibility of the proposed separation method.
