The Synthesis Platform
Several research groups have expertise in synthesising specialised materials for experiments, and an inventory of available samples has been placed below. “The inventory helps people to broaden and enrich their research, exploring composite materials they would not have thought of using before” says Luis Liz-Marzán of the Center for Cooperative Research in Biomaterials – CIC biomaGUNE, Spain, who organises the Synthesis Platform.
Samples available include polymers with different architectures. Jürgen Allgaier at Forschungszentrum Jülich, Germany, for example, synthesises well-characterised polymers, not only for colleagues in Jülich but also for other SoftComp partners. “It is important to characterise the material extremely well, in terms of chain length, molecular weight distribution and branching, for experiments,” he explains. “We have made H-branched polymers for flow experiments, which had precisely two, well-defined arms, no more and no less,” he adds. In addition, Dr Allgaier prepares polymer samples for neutron-scattering experiments, in which hydrogen atoms have been selectively replaced by the heavier isotope deuterium. Polymers with well-defined star shapes are also supplied by Dimitris Vlassopoulos and his colleagues at the University of Athens, Greece.
Another important group of materials essential for studies of soft composites are colloids; some are available through Professor Liz-Marzán and his group. They supply not only metallic nanoparticles – gold nanorods and spheres and silver platelets – but also more sophisticated materials such as latex spheres coated with carbon nanotubes. “We supply nanospheres with fluorescent tags for studies of the transport of viruses through biological membranes, for example. We have also collaborated on developing complex nanocomposites prepared from polymers and nanoparticles. The Synthesis Platform has led to many more connections between research areas than expected; it has been really successful,” he explains.
