Arizona State University Mar 2 2026 Researchers at Arizona State University have uncovered a key scientific principle that governs how what's coated on the surfaces of engineered nanoparticles may ultimately control how they work in our bodies. In a new study published in Proceedings of the National Academy of Sciences , the team directly measured how water interactions influence nanoparticle biological performance. "Water is necessary for all life," said Navrotsky, the lead author of the study,
