• Carbon-based nanomaterials have a high specific surface area, biocompatibility, and controlled mesopore structures. These characteristics make carbon nanospheres excellent carriers for drugs, biological dyes, photosensitizers, etc. Nevertheless, little is known about the impact of topological features on the surface of carbon nanomaterials on their in vivo immunoreactivity. In this study, we fabricated mesoporous carbon nanoparticles (MCNs) and solvent-processable carbon vesicles (CVs) by high-temperature calcination. The hematoxylin and eosin (H&E) staining suggested CVs' relatively poor dispersion capacity compared to MCNs and carbon precursors (CPs), leading to more severe muscle inflammation and necrosis. Immunostaining and Fluorescence Activated Cell Sorter (FACS) analysis further showed that both MCNs and CVs triggered a transient immune response in transplanted muscle and muscle-draining lymph nodes, but did not alter muscle resistance to exogenous viruses. In conclusion, this study provides insights into how carbon nanoparticles modulate the activation of immune responses in vivo. We synthesized highly ordered mesoporous carbon nanoparticles (MCNs) and solvent-processable carbon vesicles (CVs), respectively. In order to probe the bio-reactivity of MCNs and CVs, especially the in vivo immune response, we injected the carbon particles into tibialis anterior (TA) muscle of KM mice, and explored the immune cell invasion, myocytes degeneration, regeneration, immune behaviors, and susceptibility to Zika viruses.
