Figure 4

Dark field microscopic images of pH-controlled Ag-DTC breakage in Ag-DTC-DA and solvent-dependent degradation.

Dark field microscopic images of Ag-DTC-DA (a) in pH 4.5 and (b) pH 7.2 Britton-Robinson buffer with light irradiation during 30 min. Dark field microscopic images of Ag-DTC-DA in (c) ethanol (Et) and (d) n-heptane with light irradiation during 30 min. The images in square from (a–d) are the corresponding enlarged images of the near particles pointed with arrows.
