Figure 1.
UV–vis spectra of the formed {(Au3+)7-G5.NH2} complexes (curve 1); {(Au0)7-G5.NHAc} DSNPs (curve 2); {(Au3+)7-G5.NH2} complexes after reaction with glycidol for 24 h (curve 3); {(Au0)7-G5.NGlyOH} DSNPs (curve 4); and {(Au0)7-G5.NGlyOH} DSNPs formed by addition of additional glycidol (curve 5). The inset shows the photographs of the corresponding solutions of {(Au3+)7-G5.NH2} complexes (1); {(Au0)7-G5.NHAc} DSNPs (2); and {(Au0)7-G5.NGlyOH} DSNPs (4).
