The gold nanoparticle-based probe measures viral RNA in live influenza A cells, according to a study in The Journal of Physical Chemistry C. It is the first time in virology that experts have used imaging tools with gold nanoparticles to monitor mutations in influenza, with unparalleled sensitivity.
“Our probe will provide important insight on the cellular features that lead a cell to produce abnormally high numbers of viral offspring and on possible conditions that favor stopping viral replication,” said senior author Laura Fabris, an associate professor in the Department of Materials Science and Engineering in the School of Engineering at Rutgers University-New Brunswick.
