Fig. 3. SERS spectrum of ADDLs compared to that of type A+ and A− oligomers. SERS spectra of polyHis, polyGlu, polyArg and polyLys are also displayed for comparison. Bands of polyLys and/or polyArg describing relevant spectral features of type A+ oligomers and ADDLs are identified with coloured boxes.
