Porcine reproductive and respiratory syndrome virus (PRRSV), a member of the arteritis virus family, significantly impacts the swine industry due to its high infectiousness. nsp12, the nonstructural protein encoded by PRRSV, is a membrane-associated protein, with limited knowledge about its antigenic properties and functions. In this study, we used the expressed and purified nsp12 protein as antigen to immunize mice, and successfully screened five positive hybridoma cell lines that stably secrete anti-nsp12 monoclonal antibodies using immunological assays such as indirect ELISA and IFA.

Bacterial infection, tissue hypoxia, and inflammatory and oxidative stress are several key problems in wound healing of chronic infections. Herein, a multi-enzyme-like activity exhibiting multifunctional hydrogel made up of mussel-inspired carbon dot reduced-Ag (CDs/AgNPs) and Cu/Fe-nitrogen-doped carbon (Cu,Fe-NC) was designed. Due to the loss of glutathione (GSH) and oxidase (OXD)-like activity of the nanozyme (decomposes O to generate a superoxide anion radical (O˙) and hydroxyl radical production (˙OH)), the multifunctional hydrogel exhibited excellent antibacterial performance.

Nanozymes with good biocompatibility are novel antibacterial agents because they mimic the structure and properties of enzymes and destroy bacterial structures by generating reactive oxygen species in large quantities. Herein, we synthesized a Cu single-atom nanozyme (Cu-N-C) with intrinsic peroxidase- and oxidase-like activities. Cu-N-C can generate ·OH and O during oxidase-catalyzed reactions, which have good antibacterial effects.
