Schematic of proposed mechanism for dextran-coated nanoparticles heated from room temperature to 90 °C in deionized water or electrolyte solutions.
Nanoparticle cores are shown as dark gray spheres; dextran coatings are shown as light gray strands; Ca2+ ions are shown as blue dots; Mg2+ ions are shown as orange dots.
