(a) TEM image and (b) electron diffraction pattern for the ZnS nanocrystals.
(a) RRS spectra of the ZnS nanocrystals. (b) Close-up of the spectrum near the 1 LO phonon band shown in figure (a). (c) Fluorescence spectra of the ZnS nanocrystals (1) and the ZnS probe (2).
Schematic of the sandwich-structured protein detection process.
(a) RRS spectra from the sandwich-structured protein detection system for various analyte concentrations. (b) Plot of Raman intensity at (1 LO phonon line) vs analyte concentration. To aid in the presentation of the data, a logarithmic scale was adopted in figure (b). The error bars indicate one standard deviation.
