Figure 4From: Gold-silver alloy nanoshells: a new candidate for nanotherapeutics and diagnostics SEM/EDS spectra of as-synthesized gold-silver alloy nanoshells. Theoretical ratio of (A) Au:Ag = 1:1, experimental ratio Au:Ag = 3:1, and (B) Au:Ag = 5:1, experimental ratio Au:Ag = 3.6:1.Back to article page
