High-sensitivity detection of two H7 subtypes of avian influenza viruses (AIVs) by immunochromatographic assay with highly chromatic red silica nanoparticles

Anal. Methods, 2021, Advance Article
DOI: 10.1039/D1AY00204J, Paper
Zixian Su, Guangying Zhao, Wenchao Dou
In this work, high chromaticity red SiNPs were for the first time used as novel visual markers in ICA for the detection of H7 subtype influenza viruses, and the quantitative detection of the avian influenza H7 HA virus (H7N2 and H7N9) was realized by sandwich immunoassay.
