Comparison of UV-Vis spectra between colloidal nano-gold and nano-gold-SPA probes. The dash dot curve denoted UV-Vis spectrum of colloidal nano-gold within the range
of 400-700 nm. The solid curve denoted UV-Vis spectrum of colloidal gold-SPA probes
within the range of 400-700 nm. A(gold)/520 was 1.636920, whereas A(gold-SPA)/520
was 1.185927, and the loss of colloidal nano-gold was about 27.55%, which was due
to centrifugation during preparation of nano-gold-SPA probes.
