Cap in hand: The viscoelastic properties of low-molecular-mass organogelator–gold nanoparticle (LMOG–Au NP) composites can be modulated by the capping agent on the nanoparticle. The interactions between the LMOG and Au NP depend on the ability of ligands to interdigitate within the gel aggregates (see picture).
