'Instant Acid' Method Offers New Insight into Nanoparticle Dispersal in the Environment and the Body

Caption

Successive test runs at NIST show how clumping of typical nanoparticles in a solution depends on changes in acidity. Time after acidity jump is shown on the horizontal axis, while the vertical axis is a measure of the size of the nanoparticle aggregates. As pH goes down (and acidity up), both rate of aggregation and size of clumps of nanoparticles goes up.
