Changes in absorption spectra of gold nanoparticles influenced by C5F-MTSC in OF (a) and CF (b); dotted lines show the spectra of C5F-MTSC in control measurements. The volume ratio of water to ethanol was equal to 4:1. The DAE concentrations were C DAE = 1 × 10−6, 5 × 10−6, 1 × 10−5 M. The concentration of gold C Au = 2 × 10−4 M was constant for all series
