Addressing this challenge, we developed a delivery platform based on mesoporous silica nanoparticles loaded with a cell-permeable calcium chelator (BAPTA), which were uniformly spray-coated onto collagen membranes for precise control of coating thickness. In vitro, these coating ingredients were highly biocompatible, efficiently internalized by macrophages, and effectively attenuated IL4-associated cytosolic Ca<sup>2+</sup> elevation and phosphatidylserine externalization, thereby blocking cell fusion initiation. Transcriptomic analysis showed upregulation of cytomembrane-stabilizing and cytoskeletal pathways (Rap1, PI3K-Akt, focal adhesion, ECM-receptor interaction), and downregulation of apoptosis and pro-fusion pathways. In a rat subcutaneous implantation model, BAPTA-coated membranes exhibited a thickness-dependent reduction in multinucleated giant cell formation and delayed membrane degradation, without systemic toxicity. Overall, this study demonstrates that targeted modulation of intracellular calcium signaling and multi-pathway immunoregulation can inhibit macrophage fusion, stabilize cytomembrane-cytoskeleton interactions, and prolong membrane function.
