Enhanced Sonodynamic Bacterial Elimination and Wound Healing Therapy Based on Lanthanide Ion Doped Bi2WO6 Nanosheets and Hydrogel Platform

Advanced Functional Materials, Volume 35, Issue 48, November 26, 2025.
Lanthanide ytterbium ions are introduced into Bi2WO6 nanosheets to boost ROS generation under US stimulation. These ytterbium‐doped Bi2WO6 nanosheets serve as efficient sonosensitizers, enabling broad‐spectrum bacterial eradication. To improve biocompatibility for in vivo sonodynamic therapy, the sonosensitizers are integrated into hydrogel matrix ...

Emerging Advances in Nanomedicine for Targeted Cancer Photoimmunotherapy and Photo‐Immunometabolic Therapy

WIREs Nanomedicine and Nanobiotechnology, Volume 17, Issue 6, November/December 2025.
Schematic representation of nanoparticle‐mediated photothermal therapy (PTT) inducing anti‐tumor immune responses. Nanoparticles are administered to a tumor‐bearing mouse and accumulate at the tumor site. Upon laser irradiation, the nanoparticles generate reactive oxygen species (ROS) within cancer cells, leading to cellular apoptosis.

Hematoporphyrin encapsulated polymeric nanomicelles

Archives of Advances in Biosciences, 2012
Nowadays, developements in nanotechnology have leeds an increased application of this newborn technology in cancer treatment. In this study, a stabilized micelle was developed to load HpD in order to be used in photodynamic treatment of cancer in an animal model. To construct micelles, Pluronic P-105 was used and stabilized to encapsulate HpD.

Photodynamic treatment in glioma: Metabolic and structural evaluation after therapy

Photochemistry and Photobiology, Volume 101, Issue 6, Page 1380-1391, November/December 2025.
PDT with chlorin e6 reduced mitochondrial membrane potential and induced gliosarcoma cell death, mainly via apoptosis and subsequently necrosis. Microscopy and flow cytometry confirmed cytoskeletal disorganization and morphological changes. These findings highlight PDT with Ce6 as a promising therapeutic alternative for gliosarcomas, showing strong ...

Integrating Metabolic Modulation and Nanomedicine for Cancer Immunotherapy

Advanced Science, Volume 12, Issue 40, October 27, 2025.
Metabolic rewiring in cancer is mapped across glucose, amino acid, lipid, nucleotide, and mitochondrial pathways, with emphasis on immune regulation. The review integrates mechanisms linking these pathways to tumor progression and therapy resistance, and profiles nanomaterial platforms that both deliver therapeutics and actively reprogram ...

Hematoporphyrin photodynamic therapy for treatment of pathological scar with ulceration: A case report

Photodiagnosis and Photodynamic Therapy
Pathological scars result from abnormal wound healing and represent a fibrotic process in the repair of skin injuries. Post-burn scars are prone to malignant transformation, especially when ulceration occurs, raising concerns for precancerous lesions. We
