In article number 2001205, Wei and co‐workers innovatively designed a cancer defending system by a conical nano‐channel device for cancer biomarker recognition. Gates and guards which prevent the tumor outside doors imitated by the device protects the patient from recurrence and metastasis. The guards' weapons are conical nano‐channels modified with antibodies specific to the biomarker (green particle). The system‐possessed ultra‐sensitive and highly selective detection could assist clinical decision‐making and guard general health as a method breakthrough.
