From: Ordering of Hollow Ag-Au Nanospheres with Butterfly Wings as a Bio-template
(a) Comparison of Raman signal from R6G on original butterfly wing, Ag/wing and hollow Ag-Au/wing, R6G concentration: 10−3 mol/L; (b) Comparison of Raman signals from different concentrations of R6G on hollow Ag-Au/wing, R6G concentrations: 10−4 mol/L, 10−5 mol/L, 10−6 mol/L.
