Abstract
As an effective antiviral agent, the clinical application of oseltamivir (OTV) is limited by the appearance of drug-resistant viruses. Due to their low toxicity and excellent activity, the antiviral capabilities of selenium nanoparticles (SeNPs) has attracted increasing attention in recent years. To overcome the limitation of drug resistance, the use of modified NPs with biologics to explore novel anti-influenza drugs is developing rapidly. In this study, OTV surface-modified SeNPs with superior antiviral properties and restriction on drug resistance were synthesized. OTV decoration of SeNPs (Se@OTV) obviously inhibited H1N1 infection and had less toxicity. Se@OTV interfered with the H1N1 influenza virus to host cells through inhibiting the activity of hemagglutinin and neuraminidase. The mechanism was that Se@OTV was able to prevent H1N1 from infecting MDCK cells and block chromatin condensation and DNA fragmentation. Furthermore, Se@OTV inhibited the generation of reactive oxygen species and activation of p53 phosphorylation and Akt. These results demonstrate that Se@OTV is a promising efficient antiviral pharmaceutical for H1N1.

Abstract
As the therapeutic agent for antiviral applications, the clinical use of oseltamivir is limited with the appearance of drug-resistant viruses. It is important to explore novel anti-influenza drugs. The antiviral activity of silver nanoparticles (AgNPs) has attracted increasing attention in recent years and was a possibility to be employed as a biomedical intervention. Herein, we describe the synthesis of surface decoration of AgNPs by using oseltamivir (OTV) with antiviral properties and inhibition of drug resistance. Compared to silver and oseltamivir, oseltamivir-modified AgNPs (Ag@OTV) have remarkable inhibition against H1N1 infection, and less toxicity was found for MDCK cells by controlled-potential electrolysis (CPE), MTT, and transmission electron microscopy (TEM). Furthermore, Ag@OTV inhibited the activity of neuraminidase (NA) and hemagglutinin (HA) and then prevented the attachment of the H1N1 influenza virus to host cells. The investigations of the mechanism revealed that Ag@OTV could block H1N1 from infecting MDCK cells and prevent DNA fragmentation, chromatin condensation, and the activity of caspase-3. Ag@OTV remarkably inhibited the accumulation of reactive oxygen species (ROS) by the H1N1 virus and activation of AKT and p53 phosphorylation. Silver nanoparticle based codelivery of oseltamivir inhibits the activity of the H1N1 influenza virus through ROS-mediated signaling pathways. These findings demonstrate that Ag@OTV is a novel promising efficient virucide for H1N1.

Abstract
A glyco-array platform has been developed, in which glycans are attached to plasmonic nanoparticles through strain-promoted azide-alkyne cycloaddition. Glycan-protein binding events can then be detected in a label-free manner employing surface-enhanced Raman spectroscopy (SERS). As proof of concept, we have analyzed the binding of Gal1, Gal3, and influenza hemagglutinins (HAs) to various glycans and demonstrated that binding partners can be identified with high confidence. The attraction of SERS for optical sensing is that it can provide unique spectral signatures for glycan-protein complexes, confirm identity through statistical validation, and minimizes false positive results common to indirect methods. Furthermore, SERS is very sensitive and has multiplexing capabilities thereby allowing the simultaneous detection of multiple analytes.
