This study focuses on the development of a nanowire device with low cytotoxicity that effectively removes extracellular vesicles derived from cancer cells. We have been selected for the front cover.

Paper summary
Extracellular vesicles (EVs) play a crucial role in cancer cell proliferation and metastasis, and are known to induce abnormal growth in normal cells. In this study, we developed EV removal devices using zinc oxide (ZnO) nanowires and core-shell nanowires coated with titanium dioxide (TiO2) or silicon dioxide (SiO2) layers. These nanowires possess distinct surface charges, enabling them to efficiently remove different types of EVs. Among them, ZnO/SiO2 core-shell nanowires demonstrated the ability to eliminate EVs without causing cytotoxicity. Comparative studies involving the culture of normal cells in media supplemented with cancer-derived EVs and in media where cancer-derived EVs were removed by the device revealed that removing cancer-derived EVs suppressed abnormal cell proliferation in normal cells. This technology holds potential for inhibiting cancer metastasis and contributing to the development of novel therapeutic strategies.
