Mass change of RSV exposed to AuNPs functionalized with either DNA alone (gray) or DNA and Synagis antibodies (black). (A) Complete time course of experiment showing total mass bound upon flowing RSV onto the quartz crystal, followed by a PBS wash, blocking with 1% BSA, a second PBS wash, and finally functionalized AuNPs. (B) Partial time course of the same experiment comparing the change in mass upon flowing co-functionalized AuNPs or tag DNA functionalized AuNPs over RSV infected cells bound to a QCM chip.
