A Novel Nanoprobe Based on Core-Shell Au@Pt@Mesoporous SiO₂ Nanozyme With Enhanced Activity and Stability for Mumps Virus Diagnosis.

ABSTRACT: Nanoporous materials with core-shell structure have received lots of attention owing to the great versatility of the functional cores and shells and their potential application in catalysis and biological applications. In this work, a facile method has been developed to synthesize uniform Au@Pt@mesoporous SiO₂ nanostructures with high peroxidase-like activity, which had a well-defined core-shell structure with Au nanorods@Pt nanodots as a core and mesoporous SiO₂ as a shell. The mesoporous SiO₂ shell can not only provide convenient transmission channels but offer a substantial location for accommodation of large biomolecules, such as antibodies and antigens. Here a novel nanoprobe based on Au@Pt@mesoporous SiO₂ nanozyme modified with mumps antige
