Abstract
This study reports the development of a sensitive magnetic bead-based enzyme-linked immunoassay (MELISA) for the pan-reactive detection of the Influenza A virus. The assay combines immunomagnetic beads and biotin-nanoparticle-based detection to quantify a highly conserved viral nucleoprotein in virus lysates. At the capture step, monoclonal antibody-coated magnetic microbeads were used to bind and concentrate the nucleoprotein in samples. The colorimetric detection signal was amplified using biotinylated silica nanoparticles (NP). These nanoparticles were functionalized on the surface with short DNA spacers bearing biotin groups by an automated supported synthesis method performed on nano-on-micro assemblies with a DNA/RNA synthesizer. A biotin-nanoparticle and immunomagnetic bead-based assay was developed. We succeeded in detecting Influenza A viruses directly in the lysis buffer supplemented with 10% saliva to simulate the clinical context. The biotin-nanoparticle amplification step enabled detection limits as low as 3 × 103 PFU mL-1 and 4 × 104 PFU mL-1 to be achieved for the H1N1 and H3N2 strains respectively. In contrast, a classical ELISA test based on the same antibody sandwich showed detection limit of 1.2 × 107 PFU mL-1 for H1N1. The new enhanced MELISA proved to be specific, as no cross-reactivity was found with a porcine respiratory virus (PRRSV). Graphical abstract.

Abstract
The purpose of immuno-modulation is to increase or restore the action of immunocompetent cells against tumors with or without the use of monoclonal antibodies. The innate immune system is a key player in various pathological situations, but cells of this system appear to be inhibited or insufficiently active in malignancy or severe infectious diseases. The present study was designed to investigate therapeutic value of nanoparticles (NPs) coupled with bioactive hematopoietic growth factors acting on the innate immune system. The use of nanoparticles (NPs) allowing multimodal detection and multifunctional grafting are currently of great interest for theranostic purposes. In the present work, we have evaluated the impact of the number of granulocyte-colony stimulating factor (G-CSF) grafted on the surface on the NPs on the biodistribution in mice thanks to indium 111 radiolabeling. Furthermore, we have investigated whether grafted G-CSF NPs could stimulate the immune innate system and enhance the therapeutic efficacy of the monoclonal antibody rituximab in mice bearing human lymphoma xenografts. Following intravenous (i.v.) administration of NP-DTPA and NP-DTPA/G-CSF-X high levels of radioactivity were observed in the liver. Furthermore, spleen uptake was correlated with the number of G-CSF molecules grafted on the surface of the NPs. Combining NP-DTPA/G-CSF-34 with rituximab strongly reduced RL tumor growth compared to rituximab alone or in combination with conventional G-CSF + rituximab. The use of highly loaded G-CSF NPs as immune adjuvants could enhance the antitumor activity of therapeutic monoclonal antibodies by amplifying tumor cell destruction by innate immune cells.
