Preparation of functional currant-bun-like fumed silica/polymethacrylate nanoparticles by radiation-induced polymerization

- Colloidal composites based on fumed silica and polymethacrylate are prepared.
- Nanocomposites are obtained by radiation-induced polymerization under non-stirring.
- Currant-bun-like nanoparticles can be size-tuned according to the initial reagents.
- Reversible protein adsorptive properties are studied onto sulfonic nanocomposites.
- Potential applications as protein-capture materials are envisioned.
