Our zirconium phosphate (ZrP)‐promoted Ru/Co/ZrP/SiO2 catalyst reveals a high catalytic activity and stability during Fischer–Tropsch synthesis. Surface modification with ZrP on SiO2 support with an appropriate amount of phosphorous component prevents cobalt particle aggregation and enhances its stability. These positive effects of ZrP are mainly induced by the spatial confinement of cobalt particles in a thermally stable ZrP matrix, and the catalytic performance was greatly improved when the P/(Zr+P) molar ratio was 0.134 on the CoZrP(0.5) catalyst.

Mesenchymal stem cells such as human adipose tissue‐derived stem cells (hADSCs) have been used as a representative therapeutic agent for tissue regeneration because of their high proliferation and paracrine factor‐secreting abilities. However, certain points regarding conventional ADSC delivery systems, such as low cell density, secreted cytokine levels, and cell viability, still need to be addressed for treating severe wounds. In this study, we developed a three‐dimensional (3D) cavity‐structured stem cell‐laden system for overdense delivery of cells into severe wound sites. Our system includes a hydrophobic surface and cavities that can enhance the efficiency of cell delivery to the wound site. In particular, the cavities in the system facilitate hADSC spheroid formation, increasing therapeutic growth factor expression compared with 2D cultured cells. Our hADSC spheroid‐loaded patch exhibited remarkably improved cell localization at the wound site and dramatic therapeutic efficacy compared to the conventional cell injection method. Taken together, the hADSC spheroid delivery system focused on cell delivery, and stem cell homing effect at the wound site showed a significantly enhanced wound healing effect. By overcoming the limitations of conventional cell delivery methods, our overdense cell delivery system can contribute to biomedical and clinical applications.

A cancer‐selective self‐reporting sensor based on a redox‐responsive mineralized conductive hydrogel (M‐Hydrogel) is proposed with cancer‐specific viscosity, adhesive strength, stretchability, tunable conductivity, and fluorescence. The redox‐triggered release of carbonized polydopamine (cPDA) from the loaded disulfide‐crosslinked polymer dots (PD@cPDA) in the hydrogel matrix modulates the macroporous structure responsible for self‐recognizable cancer sensing and photothermal activity for cancer therapy. The self‐reporting nature of the M‐Hydrogel sensor is highlighted when in vicinity of a high glutathione (GSH) level owing to the controllable pore size and H‐bonding by cPDA, as confirmed by experiments on cancer cells (HeLa, PC3, B16‐F10‐GFP, and SNU‐C2A) and normal cells (CHO‐K1). The lower viscosity during syringe test along with the exceptional adhesiveness and stretchability with various cancer cells, combined with a high wireless pressure‐sensing response absent in normal conditions, confirms the dependence of self‐recognizable behavior on the cancer microenvironment. The M‐Hydrogel demonstrates excellent ex situ sensing with tumor ablation, after implantation in mice xenografted with HeLa cells, with the wireless sensing system, enabling real‐time analysis coupled with the upregulation of pro‐apoptotic markers P53 and BAX in the tumor. Therefore, this self‐reporting sensor may facilitate a strategy for innovative and convenient cancer diagnostics.
