Characterising the self-assembly of mixed ligand shell structures on Au nanoparticles with small-angle neutron scattering using selective deuteration of ligands
Abstract: The self-assembled structures of mixed ligands on gold nanoparticles will be studied with SANS and selective deuteration of ligands. Inorganic nanoparticles have a wide range of applications depending on their size, shape and functionalisation, including examples such as targeted cancer treatment with mixed-ligand functionalised nanoparticles or improving solar cells with thin films of fluorescent quantum dots. Ligand shells are complicated soft matter systems and mixtures of ligands may form various self-assembled phase-separated structures. This can affect the interactions of NPs with each other and their surrounding medium. Improved understanding of the driving parameters of ligand shell self-assembly would enable improved rational approaches for the design of useful ligand shell nanoparticles. The work being advanced here aims to draw a connection between viable physical parameters used to simulate mixed ligand shell self-assembly on NPs and their structural characterisation by SANS. A combination of Monte Carlo simulation and SANS measurements of mixed ligand shell NPs will be used to estimate parameters relating to ligand-NP, ligand-ligand and ligand-medium interactions.
