Nanoparticle Agglomeration: Influence of Temperature on the Colloidal Stability of Polymer‐Coated Gold Nanoparticles in Cell Culture Media (Small 13/2016)

The colloidal stability of nanoparticles can be influenced by several parameters such as temperature, ionic strength, and the presence of proteins. On page 1723, M. Karg, W. J. Parak and co-workers demonstrate core-shell nanoparticles coated with a temperature sensitive polymer. The size of the nanoparticles decreases with increasing temperature. This gives rise to a loss of the colloidal stability of the particles in media containing ions. The yellow sphere on the cover represents a gold nanoparticle, which is coated with a cross-linked temperature sensitive polymer.
