Figure 4

Intracellular uptake and fluorescence emission of hAuNP. (A) RSV-specific hAuNP emission (red) is observed in RSV-infected cells (MOI = 0.25), but not in uninfected cells (B). Blue: nuclear counterstain. Magnification 400×. (C) Gold nanoparticle immunohistochemical staining indicates that hAuNP are internalized within RSV-infected HEp-2 cells, or uninfected cells (D). Uptake is irrespective of cell infection and the intended target of hairpin DNA.
