| titleOfInvention | Gold nanoparticle based pH indicator in high alkali region by surface enhanced Raman scattering study |
| abstract | Surface-enhanced Raman scattering spectral studies showed that cyanate-reduced gold nanoparticles (about 15 nm diameter, 9 X 10 -9 M concentration, 2 X 10 -2 M ionic strength) in high alkaline regions with pH> 11, It was confirmed to show a clear color change. This indicates that gold nanoparticles reduced by citrate can be used as a color sensor that can check pH by color. Furthermore, the surface of the multi-peak of the? (C≡C) stretching band of the gold nanoparticles, in which the self-assembled monolayer is formed by an aromatic compound substituted with an acetylene group as an anchoring group, changes significantly with pH in the high alkali region. Confirmed by enhanced Raman scattering spectrum (SERS). As the pH increased, the ν (C≡C) stretching band intensity at about 2080 cm −1 gradually increased and the band intensity at about 2010 cm −1 gradually decreased. The ratio of band strength, SERS titration from I 2080 / I 2010 , confirmed that pK 1/2 was about 13. This suggests that the pH of the solution can be quantified in the high alkaline region (pH 11-14) by identifying the spectral change in the ν (C≡C) stretching band using SERS. SERS titration by the ν (C≡C) stretching band not only allows more accurate measurement of pH when compared to conventional indicators, but also allows quantification of pH in the high alkali region. |
