When manufacturers produce suspensions of nanoparticles for paints, inks, and some pharmaceuticals, they must check the charge on the particles’ surfaces. If the charges are too low, the particles will clump together, destroying the suspension and making the product ineffective. Researchers have now developed a fast method that measures nanoparticles’ charge by passing them through a nanopore (Anal.
