E‐selectin‐modified thermosensitive nanomicelles also deliver doxorubicin and A2A adenosine receptor antagonist SCH 58 261 to tumor regions through leukocyte binding, where heat radiation induces structural disintegration of NPs to release drugs that inhibit tumor growth and metastasis.[44] Previous researchers designed bacterial outer membrane vesicles (OMVs) encapsulating photothermal converters (PBIBDF‐BT), transported by neutrophils to tumor areas, where exogenous thermal stimulation triggers nanomaterial structural collapse to release loaded cisplatin for antitumor effects.[82]. Here, SELE is linked to neoplasm.
