ChemPlusChem, Год журнала: 2024, Номер 89(6)

Опубликована: Фев. 15, 2024

Reactive oxygen species (ROS) play a crucial role in orchestrating myriad of physiological processes within living systems. With the advent materdicine, an array nanomaterials has been intricately engineered to influence redox equilibrium biological milieus, thereby pioneering distinctive therapeutic paradigm predicated on ROS-centric biochemistry. Among these, two-dimensional carbides, nitrides, and carbonitrides, collectively known as MXenes, stand out due their multi-valent multi-elemental compositions, large surface area, high conductivity, pronounced local plasmon resonance effects, positioning them prominent contributors ROS modulation. This review aims provide overview advancements harnessing MXenes for catalytic reactions various applications, including tumor, anti-infective, anti-inflammatory therapies. The emphasis lies elucidating mechanism involving both pro-oxidation anti-oxidation processes, underscoring redox-related applications facilitated by self-catalysis, photo-excitation, sono-excitation properties MXenes. Furthermore, this highlights existing challenges outlines future development trends leveraging ROS-involving disease treatments, marking significant step towards integration these into clinical practice.

Ultrasmall Bi@Au Schottky Heterojunction with a High Potential Barrier for Amplifying Radioimmunotherapy

ACS Nano, Год журнала: 2025, Номер unknown

Опубликована: Март 20, 2025

Radiotherapy (RT) often has poor clinical sensitivity and tumor metastasis inhibition due to weak X-ray absorption, low energy deposition, inefficient reactive oxygen species (ROS) generation, induction of antitumor immune response. Here, we report an ultrasmall Bi@Au Schottky heterojunction, namely, nanodots (Bi@Au NDs), enhance the RT activate systemic immunity for effective treatment inhibition. NDs exhibit a high efficiency ROS generation glutathione (GSH) depletion. Density functional theory calculations reveal that with potential barrier can efficiently facilitate carrier separation prevent backflow, which results in abundant electrons catalytically decomposing H2O2 •OH under irradiation. Experimental vitro vivo show significantly sensitize by enhancing GSH ND-sensitized greatly induces immunogenic cell death thus promotes CD8+ T cell-mediated response, ultimately inhibiting metastasis. as kind heterojunctions be amplifier radioimmunotherapy.

Bi₂S₃ loaded MXene Ti₃C₂T _x nanosheet with an adsorption-photocatalytic synergistic removal for tetracycline

International Journal of Chemical Reactor Engineering, Год журнала: 2025, Номер unknown

Опубликована: Март 25, 2025

Abstract Antibiotics in water body pose a threat to the ecosystem and human health, removal of antibiotics is imperative. Ti 3 C 2 T x has high specific surface area structural stability, but suffers from low catalytic activity insufficient utilization active sites. In this paper, /Bi S composites (named PTB STB, respectively) were prepared by situ synthesis physical composite method. The introduction Bi extends light absorption visible region. Meanwhile, electron migration resistance smaller photoresponse current larger. exhibited better adsorption-photocatalytic performance than STB pure , with efficiency 89 %. addition, study investigated effects quality parameters proposed possible photocatalytic mechanism. Finally, tetracycline adsorption real samples showed good results, especially lake tap water.
