Breaking down the supramolecular ensemble: Single-molecule studies of the concentration dependence of main-chain supramolecular polymer molecular weight distributions on surfaces


Journal Article

Single molecule atomic force microscopy (AFM) studies of oligonucleotide-based supramolecular polymers on surfaces are used to examine the molecular weight distribution of the polymers formed between a functionalized surface and an AFM tip as a function of monomer concentration. For the concentrations examined here, excellent agreement with a multi-stage open association model of polymerization is obtained, without the need to invoke additional contributions from secondary steric interactions at the surface. © CSIRO 2010.
