Abstract

Our research group is interested in the application of supramolecular chemistry to understand and manipulate biology. [1,2] This is because the weak and non covalent forces that control the shape and the topology of biomolecules are governed by the principles described by supramolecular chemistry. This topology is ultimately responsible of bimolecular properties and by modulating the shape we can control and improve functional behaviour.
With focus in supramolecular interactions for artificial membranes vectors we have investigated the construction of amphiphilic peptide libraries for gene and protein delivery. [3-5]
With emphasis in synthetic biology towards bottom up approaches towards simple artificial cytoskeleton mimics, we have developed supramolecular 1D polymers in confined spaces. [6] [7]
