Colloid and Polymer Science celebrates the 300th volume! Founded in 1906 by Wolfgang Ostwald as “Zeitschrift für Chemie und Industrie der Kolloide” and renamed to “Colloid and Polymer Science” in 1974, it has now served for more than 110 years as an important periodical for research in the still emerging field of the chemistry and physics of colloids and polymers, their interdisciplinary interactions, and their applications. The list of authors who published in CPS reads like a “who is who” in colloid and polymer science and includes Nobel prize winners like R. Zsigmondy (Chemistry 1925), T. Svedberg (Chemistry 1926), J. Langmuir (Chemistry 1932), H. Staudinger (Chemistry 1953), G. Natta (Chemistry 1963), and P.G. de Gennes (Physics 1991) and researchers of highest rank like W. Ostwald, W. Kuhn, K. Blodgett, H. Ringsdorf, J.E. Mark, E.W. Fischer, and H. W. Spiess—to name a few.

The scope of CPS has lost none of its importance within the last century. Colloid and polymer science is a field of highest scientific, but also technological relevance. Nowadays, CPS is present on a worldwide scale with a team of young and experienced associate editors, whose expertise covers a wide range of topics ranging from surfactant self-assembly over polymer synthesis and biopolymers to responsive polymers, smart hydrogels, and polymer nanocomposites as well as polymers for drug delivery.

In the present issue, manuscripts are collected from leading researchers in their field. It reflects the broadness of the research published in CPS and documents the strength and continuity in which this journal expects its future.
