Here, we present a robust biomimetic nanoplatform engineered from macrophage membranes to potentiate the STING pathway-mediated immune response. This nanoplatform was designed by encapsulating MnO<sub>2</sub> and a STING agonist (SR717) within macrophage membranes, which enabled efficient accumulation at the tumor site. The reaction of MnO<sub>2</sub> and H<sub>2</sub>O<sub>2</sub> in tumors generates Mn<sup>2+</sup> and oxygen, thereby promoting the activation of the STING pathway in conjunction with SR717, while also alleviating the tumor hypoxic microenvironment.

However, direct administration of 7-D demonstrated limited efficacy in treating AKI. Here, we incorporated 7-D as the anti-ferroptotic agent and prepared it into liposomes (7-D@Lip) for the treatment of AKI. In addition, we added adenosine triphosphate (ATP) into the hydrophilic core of liposomes (7-D@A-Lip) to promote the uptake efficiency by damaged kidney cells. To enhance the distribution and accumulation of 7-D@A-Lip in the injured kidney, we extruded the renal cell membrane into the prepared liposomes (7-D@A-mLip).

The present work addresses this issue by synthesizing a bimetallic SnCu-WC<em><sub>x</sub></em> catalyst via the introduction of individual Sn and Cu atoms supported on a tungsten carbide substrate. High Faradaic efficiencies of 98.62 % and 90.19 % at current densities of 100 and 500 mA cm<sup>−2</sup> for the reduction of CO<sub>2</sub> to formate are respectively achieved through modulation of the coordination environment and electron/proton transfer during catalysis, the creation of shared adsorption sites, and the promotion of synergistic electrocatalysis. The results of operando nuclear magnetic resonance spectroscopy indicate that activated *OH groups are involved in the formation of formate due to the affinity of individual Sn atoms in the SnCu-WC<em><sub>x</sub></em> catalyst toward *OH. Density functional theory calculations confirm that the presence of individual Sn atoms in SnCu-WC<em><sub>x</sub></em> promotes the dissociation of H<sub>2</sub>O, and thereby modulates the catalytic microenvironment to accelerate the kinetics for the conversion of activated *CO to *COOH groups.

Adsorption studies reveal pH-dependent recovery behavior, with optimal performance in the pH range of 3.9–7.2. Analysis of isotherms and thermodynamics confirms the endothermic nature of the recovery process, showing a monotonic increase in the maximum adsorption capacity from 110 mg g<sup>−1</sup> to 185 mg g<sup>−1</sup> as temperature rises from 283 K to 328 K.
