Published: Jan. 29, 2024

Abstract Small molecules, including therapeutic drugs and tracer play a vital role in biological processing, disease treatment diagnosis, have inspired various nanobiotechnology approaches to realize their function, particularly drug delivery. Desirable features of delivery system for functional small molecules (FSMs) include high biocompatibility, loading capacity, simple manufacturing processes, without the need chemical modification FSM itself. Herein, we report versatile approach, based on metal–phenolic‐mediated assembly, assembling FSMs into nanoparticles (i.e., FSM‐MPN NPs) under aqueous ambient conditions. We demonstrate anticancer drugs, latency reversal agents, fluorophores at up ~80 % that is mostly facilitated by π hydrophobic interactions between nanoparticle components. Secondary engineering involving coating with polyphenol–antibody thin film or sequential co‐loading multiple enables cancer cell targeting combination delivery, respectively. Incorporating NPs visualization biodistribution different time points, revealing most these are retained kidney heart 24 h post intravenous administration.

Multi‐Enzyme Mimetic MoCu Dual‐Atom Nanozyme Triggering Oxidative Stress Cascade Amplification for High‐Efficiency Synergistic Cancer Therapy

Angewandte Chemie International Edition, Journal Year: 2024, Volume and Issue: 64(1)

Published: Aug. 22, 2024

Single-atom nanozymes (SAzymes) with ultrahigh atom utilization efficiency have been extensively applied in reactive oxygen species (ROS)-mediated cancer therapy. However, the high energy barriers of reaction intermediates on single-atom sites and overexpressed antioxidants tumor microenvironment restrict amplification oxidative stress, resulting unsatisfactory therapeutic efficacy. Herein, we report a multi-enzyme mimetic MoCu dual-atom nanozyme (MoCu DAzyme) various catalytic active sites, which exhibits peroxidase, oxidase, glutathione (GSH) nicotinamide adenine dinucleotide phosphate (NADPH) oxidase mimicking activities. Compared Mo SAzyme, introduction Cu atoms, formation synergetic effects among enhance substrate adsorption reduce barrier, thereby endowing DAzyme stronger Benefiting from above enzyme-like activities, can not only generate multiple ROS, but also deplete GSH block its regeneration to trigger cascade stress. Additionally, strong optical absorption near-infrared II bio-window endows remarkable photothermal conversion performance. Consequently, achieves high-efficiency synergistic treatment incorporating collaborative therapy This work will advance applications DAzymes provide valuable insights for nanocatalytic
