In this study, we present a novel nanoparticle with a nanoneedle-assembled shell and a magnetic core, which has great advantages over other materials used for exosome enrichment. Besides, the potential value of this nanoparticle in the enrichment and assay of exosomes has not been studied yet. The bio-inspired hierarchical nanoparticles could serve as an excellent platform for the effective capture and detection of exosomes. Thus, we believe that these novel nanoparticles are promising candidates for biological isolation and tumor diagnosis.
