    A simple method to produce ferrocenium nanoparticles (FcNPs) based on pH induced using hydrogel systems as a mini reactor is described. Hydrogels were prepared using Acryl Amide (AM),N, N' methylenebisacrylamide(MBA) as cross-linking agent,Potassium Persulfate(KPS) as the initiator and alsoTetramethlethylenediamine(TEMED)as a gelling agent. In order to prepare the nanoparticles, two different approaches were used. First, the FcNPs were prepared in-situ and secondly the hydrogel was immersed into the Ferrocenium solution at different concentrations. These nanoparticles were characterized by Fourier Thermal Infrared (FTIR), Scanning Electron Microscopy (SEM) and Transmission Electron Microscopy (TEM). The analytical results show the hydrogel systems are able to act as a mini reactor for FcNPs.
