(A) Schematic illustration of multiplexed detection based on bioplasmonic calligraphy. (B) Longitudinal LSPR wavelength shift of AuNRs functionalized with human IgG and mouse IgG corresponding to exposure of the calligraphed paper to goat anti-human IgG, goat anti-mouse IgG, and the mixture of both (inset: image of NR–human IgG and NR–mouse IgG written on paper). (C) Longitudinal LSPR wavelength shift of NR–human IgG and NR–mouse IgG corresponding to exposure of the calligraphed paper to the mixture of different concentrations of goat anti-mouse IgG and the constant concentration of goat anti-human IgG.
