prepared an artificial NK cell (aNK), which was formed by coating perfluorohexane (PFC) and glucose oxidase (GOX) with red blood cell membrane (RBCM).[188] The aNK could directly kill tumor cells by decomposing glucose to generate H2O2 under the catalysis of GOX, in which the catalytic reaction was also strengthened by oxygen‐carried PFC. Here, HAO1 is linked to neoplasm.
