Abstract Modifying the coordination or local environments of single‐, di‐, tri‐, and multi‐metal atom (SMA/DMA/TMA/MMA)‐based materials is one best strategies for increasing catalytic activities, selectivity, long‐term durability these materials. Advanced sheet supported by metal atom‐based have become a critical topic in fields renewable energy conversion systems, storage devices, sensors, biomedicine owing to maximum utilization efficiency, precisely located centers, specific electron configurations, unique reactivity, precise chemical tunability. Several offer excellent support are attractive applications energy, medical research, such as oxygen reduction, production, hydrogen generation, fuel selective detection, enzymatic reactions. The strong metal–metal metal–carbon with metal–heteroatom (i.e., N, S, P, B, O) bonds stabilize optimize electronic structures atoms due interfacial interactions, yielding activities. These provide models understanding fundamental problems multistep This review summarizes substrate structure‐activity relationship different active sites based on experimental theoretical data. Additionally, new synthesis procedures, physicochemical characterizations, biomedical discussed. Finally, remaining challenges developing efficient SMA/DMA/TMA/MMA‐based presented.

Therapeutic Approaches with Iron Oxide Nanoparticles to Induce Ferroptosis and Overcome Radioresistance in Cancers

Pharmaceuticals, Journal Year: 2025, Volume and Issue: 18(3), P. 325 - 325

Published: Feb. 26, 2025

The emergence of nanotechnology in medicine, particularly using iron oxide nanoparticles (IONPs), may impact cancer treatment strategies. IONPs exhibit unique properties, such as superparamagnetism, biocompatibility, and ease surface modification, making them ideal candidates for imaging, therapeutic interventions. Their application targeted drug delivery, especially with traditional chemotherapeutic agents like cisplatin, has shown potential overcoming limitations low bioavailability systemic toxicity chemotherapies. Moreover, IONPs, by releasing ions, can induce ferroptosis, a form iron-dependent cell death, which offers promising pathway to reverse radio- chemoresistance therapy. In particular, demonstrate significant radiosensitisers, enhancing the effects radiotherapy promoting reactive oxygen species (ROS) generation, lipid peroxidation, modulating tumour microenvironment stimulate antitumour immune responses. This review explores multifunctional roles radiosensitisation through ferroptosis induction, highlighting their promise advancing head neck cancers. Additional research is crucial fully addressing clinical settings, offering novel approach personalised treatment.

Synergistic interplays involving multiple active centers originating from TiO 2 nanotube layers (TNT) and ruthenium (Ru) species comprising of both single atoms (SAs) nanoparticles (NPs) augment the alkaline hydrogen evolution reaction (HER) by enhancing Volmer kinetics rapid water dissociation improving Tafel efficient H* desorption. Atomic layer deposition Ru with 50 process cycles results in a mixture SAs 2.8 ± 0.4 nm NPs present on TNT layers, it emerges highest HER activity among all electrodes synthesized. A detailed study Ti using different high‐resolution techniques confirmed presence 3+ states coexistence NPs. With insights literature, role , appropriate work functions Ru, synergistic effect performance were elaborated justified. The aforementioned characteristics led to remarkable having 9 mV onset potentials 33 dec −1 slopes higher turnover frequency 1.72 H s at 30 mV. Besides, notable stability 28 h staircase chronopotentiometric measurements for TNT@Ru surpasses TNT@Pt comparison.
