    • TEM observation revealed that the size of the gels containing gold ions (obtained after purification using distilled water at pH 7.0) was only slightly larger (ca. 5%) than that of bare microgels (Supporting Information Figure S2), which can be caused by the incorporation of gold ions into microgels. This indicates that ion-doped gels are in a shrunken state at neutral pH.

    • The average interparticle spacings were estimated using the average number of gold nanoparticles per microgel (by TEM observation) and the average diameter of the nanocomposite microgels (by DLS measurement) at pH 1.0 and 2.0 on the basis of an assumption of a simple square arrangement of gold nanoparticles on the microgel surface.
