Recent studies have highlighted porous nanoparticles as promising candidates for tissue sealants, where not only adhesion to wound surfaces but also cohesion among nanoparticles critically determines overall performance. To strengthen cohesion, previous studies have proposed integrating porous nanoparticles with polymers, enabling polymer chains to encapsulate or infiltrate the nanopore framework. Understanding the mechanisms of polymer–nanoparticle interactions is therefore essential for optimizing adhesive materials. In this study, we introduce a multiscale coarse-grained simulation framework to investigate polymer–nanoparticle mixtures. Our model examines how key structural and physical parameters—including nanoparticle size, pore architecture, surface characteristics, particle concentration, and polymer molecular weight—influence polymer adsorption, infiltration, and interparticle bridging. The findings provide molecular-level insights into how porous architectures enhance cohesion, offering design principles for the development of next-generation nanoparticle-based tissue sealants.
