Abstract
Removing excessively produced cytokines is of paramount significance in blood purification therapy for hypercytokinemia-associated diseases. In this study, we devised a conduit that is modified with nanobodies (Nb) and incorporates static mixers (Nb-SMC) to eliminate surplus cytokines from the bloodstream. The low-pressure-drop (LPD) static mixer, with each unit featuring two 90°-crossed blades, was strategically arranged in a tessellated pattern on the inner wall of the conduit to induce turbulent mixing effects during the flow of blood. This arrangement enhances mass transfer and molecular diffusion, thereby assisting in the identification and elimination of cytokines. By utilizing computational fluid dynamics (CFD) studies, the Nb-SMC was rationally designed and prepared, ensuring an optimal interval between two mixer units (H/G = 2.5). The resulting Nb-SMC exhibited a remarkable selective clearance of IL-17A, reaching up to 85 %. Additionally, the process of Nb immobilization could be adjusted to achieve the simultaneous removal of multiple cytokines from the bloodstream. Notably, our Nb-SMC displayed good blood compatibility without potential adverse effects on the composition of human blood. As the sole documented static mixer-integrated conduit capable of selectively eliminating cytokines at their physiological concentrations, it holds promise in the clinical potential for hypercytokinemia in high-risk patients. STATEMENT OF SIGNIFICANCE: High-efficient cytokines removal in critical care still remains a challenge. The conduit technique we proposed here is a brand-new strategy for cytokines removal in blood purification therapy. On the one hand, nanobody endows the conduit with specific recognition of cytokine, on the other hand, the build-in static mixer enhances the diffusion of antigenic cytokine to the ligand. The combination of these two has jointly achieved the efficient and specific removal of cytokine. This innovative material is the only reported artificial biomaterial capable of selectively eliminating multiple cytokines under conditions close to clinical practice. It has the potential to improve outcomes for patients with hypercytokinemia and reduce the risk of adverse events associated with current treatment modalities.

Abstract
Nanobodies have gained widespread application in immunoassays. However, their small size presents a significant challenge in achieving effective immobilization and optimal sensitivity. Here, we present a novel "one-for-two"-oriented immobilization platform based on an organism-bispecific nanobody (O-BsNb) scaffold, enabling highly sensitive detection of two bacterial pathogens. Through genetic engineering, a bispecific nanobody (BsNb) was engineered, targeting Salmonella spp. and Vibrio parahaemolyticus. The O-BsNb scaffold allowed one nanobody to bind specifically to inactivated bacteria, forming an organism-oriented immobilization platform, while the other served as the capture antibody. Consequently, the O-BsNb bioscaffold-based ELISA (O-ELISA) for individual detection of S. enteritidis and V. parahaemolyticus was established. When compared to the sandwich ELISA utilizing passive immobilization of monovalent nanobodies, the O-ELISA exhibited a remarkable 13.4- and 13.7-fold improvement in LOD for S. enteritidis and V. parahaemolyticus, respectively, highlighting the enhanced immobilization efficacy of the O-ELISA. Furthermore, the feasibility and reproducibility of the assay in practical samples were meticulously evaluated, revealing exemplary performance in terms of recovery precision and assay stability. These findings demonstrate the significant potential of the O-ELISA platform for the sensitive detection of macromolecules, opening new avenues for efficient pathogen identification in foodborne safety and clinical diagnostics.

Abstract
The influence of preparation material residues in wastewater and soil on plants has been paid more and more attention by researchers. Secondary metabolites play an important role in the application of plants. It was found that nanomaterials can increase the content of plant secondary metabolites in addition to their role in pharmaceutical preparations. For example, 800 mg/kg copper oxide nanoparticles (NPs) increased the content of p-coumaric acid in cucumber by 225 times. Nanoparticles can cause oxidative stress in plants, increase signal molecule, and upregulate the synthase gene expression, increasing the content of secondary metabolites. The increase of components such as polyphenols and total flavonoids may be related to oxidative stress. This paper reviews the application and mechanism of metal nanomaterials (Ag-NP, ZnO-NP, CeO2-NP, Cds-NP, Mn-NP, CuO-NP) in promoting the synthesis of secondary metabolites from plants. In addition, the effects of some other preparative materials (cyclodextrins and immobilized molds) on plant secondary metabolites are also involved. Finally, possible future research is discussed.
