Fig. 3. In vitro stripping voltammetric curves of a carbon electrode exposed to a solution of 1.26 pM influenza virus covered with silver nanoparticles at different designated immersion times. (Inset) linear relation between the total stripping charge as a function of immersion time at open circuit potential. The red circle corresponds to the stripping charge observed in a solution containing silver nanoparticles only, after 40 min exposure to an open circuit potential. A silver nanoparticle concentration of 8 nM was used for all the solutions.
