Colloid and interface science deals with chemical and physical processes and phenomena at interfaces. Macroscopic surfaces represent an important type of interfaces where colloid and interface science have made important contributions, for example for anti-icing of surfaces, environmentally friendly lubricants in engines and production, non-stick surface coatings, and many others. However, it is primarily in nanomaterials that colloid and interface science has made transformative contributions to our society. Thus, when particulate matter becomes very small in size, interfaces dominate the properties and performance of such systems. Furthermore, the underlying phenomena controlling such systems frequently override system-specific properties. As a result of this, knowledge of nanoparticulate systems can frequently be transferred from one context (and industrial areas) to another.

Combined with the direct influence of key concepts within colloid and interface science, such as intermolecular interactions, adsorption, colloidal stability, and self-assembly for a wide range of products, the area is furthermore characterized by considerable industrial engagement also in academic research.

Although a number of groups in Denmark are working within the area of colloid and interface science, there is the absence of a comparable strategic focus on colloid and interface science in Denmark, notably in the area of soft matter. However, a number of groups have built successful research in various areas sub-areas of colloid and interface science, as well as soft matter applications of these. Examples include a number of groups working on pharmaceutical formulations and drug delivery systems, groups within the food area, and groups addressing fundamental aspects of colloid and interface science.

The purpose of the proposed center initiative is to link together these groups, initially focusing on researchers at the University of Copenhagen in order to pursue center´s vision.

The initiative sets out to strengthen:

1. international impact,
2. funding both nationally and internationally,
3. industrial collaboration and research translation,
4. and undergraduate and graduate training of students within this area of wide industrial applicability and considerable opportunities for entrepreneurship.

In the way ahead, a number of steps are currently addressed, including: 

• sharper definition of sub-areas to be covered, 
• identification of additional participating groups to further strengthen the center, 
• definition of strategies for reaching wider impact, strengthening project funding, streamlining industrial collaborations and more broadly research translation,
• and establishment of forms for interaction, including joint research, projects, exchange of students and staff, and sharing of instrumentation and infrastructure.

Together, we anticipate these activities to contribute to the overall aims of the center, including:

1. Strengthening colloid and interface science in Denmark, with initial focus on the University of Copenhagen.
2.  Enabling research in the area not presently available to individual groups.
3. Establishing structures for efficient use/flow of staff/instrumentation between groups.
4. Providing a platform for realizing large-scale projects motivated by strategic needs in Denmark.
