proposed an in situ‐activated nanoplatform, Cu2O/BNN6@MSN‐Dex, for selective tumor inhibition and synchronous elimination of the CRC‐resident pathogenic bacterium Fn through combined PTT and GT (Figure 12).[188] This nanoplatform was constructed by loading cuprous oxide (Cu2O) and BNN6 into dextran (Dex)‐decorated MSN, in which the formed boronate linkage between phenylboronic acid (PBA) and Dex enabled pH‐/H2O2‐sensitive performance. Here, FN1 is linked to colorectal carcinoma.
