Summary: Photodynamic therapy (PDT) is limited by tumor oxygen heterogeneity, but a novel oxygen level-responsive nanomedicine is reported here. This nanomedicine consists of a hypoxia-responsive molecule (Cy-NO2), a radical generator (ADVN), and a pH-responsive polymer. Under normoxic conditions, Cy-NO2 acts as a photosensitizer for effective PDT, while under hypoxic conditions, it transforms into a photothermal agent to generate toxic free radicals for thermodynamic therapy. This study offers a promising strategy for smart cancer therapy by overcoming oxygen heterogeneity.

Summary: This article discusses the role of reactive oxygen species (ROS) in normal and malignant colonic cell biology and explores how existing and emerging therapies can utilize ROS for therapeutic benefit. Recent research has shed light on the contribution of ROS to the cytotoxicity of conventional chemotherapy, as well as the generation of ROS in response to excitatory stimuli in emerging therapies such as photodynamic therapy, sonodynamic therapy, and radiodynamic therapy. However, the poor prognosis and resistance associated with metastatic colorectal cancer necessitate the development of new and more effective treatments.

Summary: In this study, three types of red-emissive carbon dots (RCDs) were successfully prepared with maximum emission at approximately 680 nm. The RCDs exhibited adjustable generation of reactive oxygen species (ROS) through type I and type II photodynamic therapy (PDT). The unique ROS formation of RCDs was determined by their core sizes and surface states, and they were able to induce cell programmed death via activating mitochondrion-mediated apoptotic pathways. This work provides a new prospect for RCDs as nanophotosensitizers to overcome the limitations of single type PDT.

Summary: Glioma, the most common primary intracranial tumor in adults, has poor prognosis. Current treatment methods, including surgery and chemoradiotherapy, have limited efficacy. The emerging field of nanotechnology offers a new approach called reactive oxygen species (ROS)-based nanotherapy, which generates large amounts of ROS in glioma cells to effectively eliminate the tumor. Nanotechnology also provides strategies to cross the blood-brain barrier, allowing effective ROS-based nanotherapy for glioma. This review summarizes the application of ROS-based nanomedicine in glioma treatment and discusses the current challenges and future prospects for clinical translation.

Summary: The synthesis and characterization of two new water soluble perylenediimides, PDI-1 and PDI-2, with potential applications in anticancer activities were described. These compounds demonstrated high fluorescence quantum yield in water and showed selective cytotoxicity toward cancer cells when exposed to specific light wavelength. The findings provide a strong foundation for the future exploration of PDI-1 and PDI-2 as effective photosensitizers in photodynamic therapy.

Summary: Chlorophyllin-assisted photodynamic therapy has shown strong anti-cancer effects on human cervical cancer by inducing apoptosis through oxidative stress. The optimal conditions for photodynamic therapy have been determined, and it regulates the expression of several proteins and suppresses the phosphorylation of AKT1. Overall, chlorophyllin-assisted photodynamic therapy has the potential to be used as an antitumor therapy for cervical cancer.
