• insufficient targeting. The 4T1 cell membrane-coated NPs exert multiple antitumor functions after entering the blood circulation and targeting tumor tissues [23]. This targeted strategy, which does not depend on ER, RR, or HER2, shows good prospects for the treatment of metastatic TNBC. 3.2 Hematological

• biomimetic NPs consists of poly(citrate–peptide) (PCP) and miRNA365 mimic as the core and are coated with the MC38 cell membrane. After targeting tumor tissue, the NPs exert antitumor effects by inhibiting the expression of Ki67/Bcl2 and enhancing tumor cell apoptosis [55]. This strategy combining gene

Secondly, defects of the lymphatic system in tumors prevent these macromolecular therapeutics to be cleared from the tumor, giving them additional time to release their active cargo. This was the first example of targeting tumor tissues

Under physiological conditions, the nanoparticle surface is exposed to the action of biomolecules, oxygen, peroxides, and radicals, which changes particle properties and behavior. Moreover, Fe2+ ions can
