In this study the potential applications of manganese ferrite (MnFe2O4) nanoparticles for bioanalytical applications are evaluated. These magnetic nanoparticles show peroxidase-like activity similar to that reported for magnetite nanoparticles and peroxidase enzyme. Based on this finding, colloidal suspensions of manganese ferrite were conjugated to an anti-Sticholysin II (StII) monoclonal antibody. The resulting conjugate was then used as a revealing tool in a novel immunoassay for StII detection. From the combined magnetic properties and specific recognition of anti-StII-MnFe2O4 conjugate, Sticholysins were separated from whole aqueous extract of marine anemone obtaining 75% of purity. The results herein discussed illustrate the potential applications of manganese ferrite nanoparticles as bioanalytical tools for immunoassay and protocol for protein separation.
