An open resource for intermolecular interactions,
comprising currently 5244 peer-reviewed interactions including 2239 molecules.

developed at the Biedermann Labs

Mission Statement

The SupraBank is providing detailed information of intermolecular interactions. Especially host:guest interactions are covered, but also ligand:protein interactions, and polymer interactions as well as surface adsorption processes can be managed. The reporting of conditions during the analysis of intermolecular interactions, such as binding isotherms, are in general annotated in text-based publications in virtue of human readability. In order to compare binding data, the conditions of the experiments should be structured and machine readable for facile processing. Here the SupraBank offers the scientists a platform to view the experimental data structured for human readability at the web interface, but also offers machine-readable access. This platform is supposed to be a useful tool for all natural sciences, but especially for physical chemistry and supramolecular chemistry.

Our servers are located at the Institute of Nanotechnology (INT) at Campus North of the Karlsruhe Institute of Technology (KIT) in Germany. The german electricity mix is generated by approximately 45% renewable energy sources such as wind or solar power plants. Additionaly, at the KIT campus north (KIT CN), a solar power plant provides around 1 GWh p.a. to the entire electricity consumtion of around 80 GWh p.a. of KIT CN resulting in an overall percentage of 46% renewable electrical energy for our servers.

The SupraBank team fully respects all genders and sexual orientations. In some descriptive texts on the SupraBank, researchers or scientists are explicitly addressed in form of a user story, making it easier to understand the process of research data management. In these texts, the subject is addressed with pronouns such as "he" or "she", which ALWAYS includes all genders and is supposed to address all researchers or scientists independent of their gender. Nobody is excluded and everybody is welcome to use and contribute to the SupraBank!
