Abstract Cancer cells engage in active aerobic glycolysis to meet their bioenergetic synthesis needs, which is known as the Warburg effect. Such a process leads lactate accumulation tumor microenvironment (TME), further promoting cancer progression and inducing immunosuppression. Herein, functionalized dendrimer‐Cu(II) complexes (for short, D‐Cu(II)) nanocarrier, enables Fenton‐like reaction developed generate large amount of hydroxyl radicals shows T 1 ‐weighted magnetic resonance (MR) imaging performance. Importantly, D‐Cu(II) allows efficient delivery oxidase (LOx) cells, directly downregulating levels. When combining with an immune activator leukadherin‐1, D‐Cu(II)/LOx alleviate symptoms mouse leukemia. With coating macrophage membranes, generated D‐Cu(II)/LOx@M for effective blood‐brain barrier crossing treat orthotopic murine glioma model under guidance Cu(II)‐facilitated MR imaging. By integrating LOx‐mediated depletion Cu(II)‐mediated chemodynamic therapy, dendrimer nanomedicines improve overall survival antitumor responses mice, help remodel immunosuppressive TME both models, greatly sensitizing treatment efficacy activator. technology may be used theranostics other types through depletion‐enhanced combinational therapy.

Currently, biomineralization is widely used as a surface modification approach to obtain ideal material surfaces with complex hierarchical nanostructures, morphologies, unique biological functions, and categorized organizations. The fabrication of biomineralized coating for the scaffolds, especially synthetic polymer can alter characteristics, provide favorable microenvironment, release various bioactive substances, regulate cellular behaviors osteoblasts, promote bone regeneration after implantation. However, fabricated by immersion in simulated body fluid has disadvantages non-uniformity, instability, limited capacity act an effective reservoir ions regeneration. In this study, order osteoinductivity 3D-printed PCL we optimized procedure nano-topographical guidance. Compared constructed conventional method, nano-topographically guided possessed more mineral substances firmly existed on scaffolds. Additionally, better protein adsorption ion capacities. To end, present work also demonstrated that scaffolds USCs, guide osteogenic differentiation biomimetic microenvironment
