Multifunctional supramolecular vesicles for combined photothermal/photodynamic/hypoxia-activated chemotherapy

Multifunctional supramolecular vesicles were constructed by self-assembly of water-soluble pillar[5]arene and NIR-absorbing guest G. They exhibited remarkable antitumor efficacy through simultaneous combination of photothermal, photodynamic and photodynamic-triggered hypoxia-activated chemotherapy.

Indocyanine Green-holo-Transferrin Nanoassemblies for Tumor-Targeted Dual-Modal Imaging and Photothermal Therapy of Glioma

Active-targeted cancer imaging and therapy of glioma has attracted much attention in theranostic nanomedicine. As a promising tumor-targeting ligand, holo-transferrin (holo-Tf) has been applied for enhancing delivery of nanotheranostics. However, holo-Tf-based nanoassemblies for active targeting mediated multimodal imaging and therapeutics have not been previously reported. Here, we develop a one-step method for the preparation of holo-Tf-indocyanine green (holo-Tf-ICG) nanoassemblies for fluorescence (FL) and photoacoustic (PA) dual-modal imaging and photothermal therapy (PTT) of glioma. The nanoassemblies are formed by hydrophobic interaction and hydrogen bonds between holo-Tf and ICG, which exhibit excellent active tumor-targeting and high biocompability. The brain tumor with highly expressed Tf receptor can be clearly observed with holo-Tf-ICG nanoassemblies base on FL and PA dual-modal imaging in subcutaneous and orthotopic glioma models. Under the near-infrared laser irradiation, the holo-Tf-ICG nanoassemblies accumulated in tumor regions can efficiently convert laser energy into hyperthermia for tumor ablation. The novel theranostic nanoplatform holds great promise for precision diagnosis and treatment of glioma.
