Development of innovative nanomedicine formulations to traverse the blood–brain barrier (BBB) for effective theranostics glioma remains a great challenge. Herein, we report creation macrophage membrane-camouflaged multifunctional polymer nanogels coloaded with manganese dioxide (MnO2) and cisplatin magnetic resonance (MR) imaging-guided chemotherapy/chemodynamic therapy (CDT) orthotopic glioma. Redox-responsive poly(N-vinylcaprolactam) (PVCL) (NGs) formed via precipitation polymerization were in situ loaded MnO2 physically encapsulated have mean size 106.3 nm coated membranes good colloidal stability. The generated hybrid NGs display dual pH- redox-responsive Mn(II) release profiles can deplete glutathione (GSH) rich tumor microenvironment through reaction disulfide-containing cross-linkers within MnO2. thus created enables enhanced CDT Fenton-like T1-weighted MR imaging, while not only exerts its chemotherapy effect but also promotes reactive oxygen species generation enhance efficacy. Importantly, membrane coating rendered prolonged blood circulation time ability BBB specific targeted chemotherapy/CDT Our study demonstrates promising self-adaptive cooperative NG-based platform highly efficient glioma, which may be extended tackle other difficult cancer types.

Cancer is one of the most intractable diseases owing to its high mortality rate and lack effective diagnostic treatment tools. Advancements in micro-/nanorobot (MNR)-assisted sensing, imaging, therapeutics offer unprecedented opportunities develop MNR-based cancer theragnostic platforms. Unlike ordinary nanoparticles, which exhibit Brownian motion biofluids, MNRs overcome viscous resistance an ultralow Reynolds number (Re << 1) environment by self-propulsion. This unique locomotion property has motivated advanced design functionalization as a basis for next-generation cancer-therapy platforms, potential precise distribution improved permeation therapeutic agents. Enhanced barrier penetration, imaging-guided operation, biosensing are additionally studied enable promising cancer-related applications MNRs. Herein, recent advances therapy comprehensively addresses, including actuation engines, diagnostics, medical targeted drug delivery; research that can have profound impact on over next decade highlighted.

Abstract Cuproptosis, a newly discovered cell death pathway, has shown great potential in cancer treatment. Herein, near‐infrared (NIR) light‐driven nanomotors (CuSiO 3 @Au‐Pd NMs) are designed for cuproptosis‐assisted synergistic therapy with autonomous mobility and improved cellular uptake tumor penetration. Specifically, the released Cu 2+ ions from CuSiO NMs can induce Fenton‐like reaction, leading to generation of hydroxyl radicals (·OH), accompanied by depletion glutathione within MCF‐7 cells. Additionally, also exhibit excellent photothermal effects, which further promote production ·OH, resulting intensified oxidative stress apoptosis. Moreover, enhanced permeation efficiency via movement under self‐thermophoretic forces proved using 2D experiments 3D multicellular spheroids.

Gastric cancer (GC) is a serious disease with high morbidity and mortality rates worldwide. Chemotherapy plays key role in GC treatment, while inevitable drug resistance systematic side effects hinder its clinical application. Fenton chemistry-based chemodynamic therapy (CDT) has been used as strategy for ferroptosis, the CDT efficiency could be enhanced by photothermal (PTT). With trend of treatment diagnosis integration, combination magnetic resonance imaging (MRI) CDT/PTT exhibits enormous progress. Herein, we constructed platform based on PEGylated manganese-containing polydopamine (PDA) nanoparticles, named PEG-PDA@Mn (PP@Mn) NPs. The PP@Mn NPs were stable globular. Furthermore, they demonstrated near-infrared (NIR)-triggered PTT Fenton-like reaction-based T1-weighted MRI capabilities. According to vitro studies, trigger ferroptosis cells producing abundant reactive oxygen species (ROS) via reaction combined PTT. vivo studies showed that, under guidance, at tumor region, have anti-tumor effect. In conclusion, provide an effective synergistic GC.
