Perhaps the most promising feature of our polymer-bridge mediated attachment of nanoparticles, is the ability to encode mixtures of chemical functionalities into the "Swiss-army-knife" pPFPAC polymer backbone, and thus obtain a truly modular approach to nanoparticle support via appropriate selection of the chemical groups. Specifically, we demonstrate this potential by incorporating thiol groups in addition to the nitro-catechol functionality to enable attachment of both metal-oxide and metal nanoparticles separately to the same SiO 2 microparticle support. We choose thiol groups for their well-known ability to form strong bonds with a range of metal surfaces.
