Abstract:

In the present study, we developed a novel colorimetric strategy for the visible rapid detection of the influenza virus based on the unique optical properties of gold nanorods. Specifically, lipoic acid-modified Oseltamivir (OS), which is a strong neuraminidase inhibitor and used as the first-line drug in the treatment of influenza, was synthesized and further attached to the surface of gold nanorods (OS-LA-GNRs). The absorption band and density of OS-LA-GNRs were changed with the decreasing distance between the nanoparticles induced by the target-specific aggregation via strong neuraminidase–OS binding. All of these could be visible with the naked eyes and measured by UV-visible spectrophotometry. The results showed that our system had a comparable limit of detection (LOD) to the commercial colloidal gold stripes, making it feasible for wide diagnostic applications.
