A new integrated microfluidic system was developed to detect multiple types of the influenza virus.
The change in conformation of a single universal influenza aptamer exposed to different ion concentrations could detect three different influenza viruses.
Fast diagnosis of influenza A H1N1, H3N2 and influenza B could be automated on an integrated microfluidic system within 30 min by using a single universal aptamer exposed to different ion concentrations.
