Researchers at Texas A&M University have found a way to control the charge of nanoparticles on a two-fluid interface to create a more stable system in which its charge can also be switched and controlled. The ability to change the charge of nanoparticles on a two-fluid interface — specifically, an oil-water interface — would result in a surface that could acclimate itself to fit many diverse applications, such as a more durable firefighting operation and even controlled release in certain medications.
