For biomaterial applications, it is important that the properties of self-assembled hydrogels are well controlled and match the requirements of the application. The influence of the surrounding surface properties on gel characteristics is poorly understood but very important because it is always present. Preliminary data shows a measurable impact of particle inclusion in the gel on gel stiffness (rheology) and gel fibre structure (AFM). Here, we aim to use scattering techniques to understand the changes caused in the structure of gel fibres when particles with different surface properties are present in the gel. This will lead to a better understanding of the influence of particles on gel properties and, hence, the performance of composite gels to enable rational design and control over these widely used materials.
