Photodynamic therapy is an important tool in modern medicine due to its effectiveness, safety, and the ability to provide targeted treatment for a range of diseases. Photodynamic therapy utilizes photosensitizers to generate reactive oxygen species (ROS). Fullerenes can be used as photosensitizers to produce ROS in high quantum yields.

NIR Triggered Bionic Bilayer Membrane-Encapsulated Nanoparticles for Synergistic Photodynamic, Photothermal and Chemotherapy of Cervical Cancer.

Int J Nanomedicine

January 2025

State Key Laboratory of Pathogenesis Prevention and Treatment of High Incidence Diseases in Central Asia, School of Medical Engineering and Technology Xinjiang Medical University, Urumqi, 830011, People's Republic of China.

Purpose: A synergistic treatment strategy of phototherapy and chemotherapy has been shown to improve efficacy and offer unique advantages over monotherapy. The purpose of this study is to explore a new nanocarrier system with liposome as the inner membrane and erythrocyte membrane as the outer membrane, which aims to realize the leak-free load of phototherapy drug indocyanine green (ICG) and chemotherapy drug doxorubicin (DOX), prolong the circulation time in vivo and improve the therapeutic effect.

Patients And Methods: In this study, bilayer membrane-loaded ICG and DOX nanoparticles (RBC@ICG-DOX NPs) were prepared and characterized.

Macrophage membrane-camouflaged pure-drug nanomedicine for synergistic chemo- and interstitial photodynamic therapy against glioblastoma.

Acta Biomater

Shanghai Frontiers Science Center of Drug Target Identification and Delivery, National Key Laboratory of Innovative Immunotherapy, School of Pharmaceutical Sciences, Shanghai Jiao Tong University, Shanghai 200240, China. Electronic address:

Glioblastoma (GBM) persists as a highly fatal malignancy, with current clinical treatments showing minimal progress over years. Interstitial photodynamic therapy (iPDT) holds promise due to its minimally invasive nature and low toxicity but is impeded by poor photosensitizer penetration and inadequate GBM targeting. Here, we developed a biomimetic pure-drug nanomedicine (MM@CT), which co-assembles the photosensitizer chlorin e6 (Ce6) and the first-line chemotherapeutic drug (temozolomide, TMZ) for GBM, then camouflaged with macrophage membranes.

Electronic address:

The development of biomass material is an important approach to alleviating the excessive using of plastic packaging, by which the product could be more environmentally friendly and lower toxicity. In this study, we developed a biodegradable photodynamic antibacterial food packaging film using nitrogen-doped carbon quantum dots (N-CQDs) synthesized from crayfish shells, combined with konjac glucomannan (KGM) and sodium alginate (SA). Casting method was used to prepare the composite film and results indicated that incorporation of N-CQDs significantly enhanced the mechanical and barrier properties of the film by reducing the number of micropores.
