Absorbance Data: AuNPs@SiO2
Spectra for silica-coated AuNPs made with MHA dissolved in water is consistent with spectra found in the literature. The noticeable shift towards the right in the spectra for silica-coated AuNPs made with MHA dissolved in isopropanol is indicative of aggregation. Additionally, the AuNPs-MHA in isopropanol solution was a deep purple color, also consistent with aggregation, while the AuNPs-MHA in water was the characteristic pink color of gold nanoparticles in solution.
