Abstract:

In recent years, with the continuous development of nanotechnology, multifunctional nanocomposites have been widely applied in the field of tumor therapy. Due to the heterogeneity, complexity, and diversity of tumors, single treatment approaches often fail to achieve ideal therapeutic outcomes. Therefore, combining multiple treatment methods to achieve synergistic tumor therapy has become a research hotspot. This paper designs a novel nanotherapy platform. A polydopamine(PDA) shell was coated on the surface of Pt@mesoporous Au nanomaterials(Pt@Au), and doxorubicin(DOX) was loaded into the PDA shell. The surface of the PDA shell was modified with glucose oxidase(GOx) and NH2-PEG5K-cRGD. NH2-PEG5K-cRGD can specifically bind to the overexpressed αvβ3 integrin in tumor cells, facilitating the accumulation of the nanotherapy platform in the tumor region. DOX can damage the DNA of tumor cells and is used for chemotherapy. The excellent photothermal properties of mesoporous Au and PDA can be used for photothermal therapy. GOx can react with glucose in tumor cells to produce gluconic acid and H2O2, achieving starvation therapy. Pt, as a common peroxidase mimic, can catalyze the decomposition of H2O2 in tumor cells to generate O2, alleviating the hypoxic tumor microenvironment and promoting starvation therapy. Therefore, the Pt@Au@PDA-DOX-GOx-cRGD possesses the ability to perform chemotherapy-photothermal therapy-self-enhanced starvation therapy for combined tumor treatment.
