iDFM and spectra of silver nanospheres during the light-driven Ag-DTC breakage and the inhibition of sulfidation process with sodium ascorbate (SA) and the reverse reaction with NaBH4.
(a) Simultaneous iDFM and spectroscopic measurements of a single nanosphere during the light-driven reaction. (b) The iDFM image of treatment with 100 mM SA. (c) The scattering intensity of the nanoparticles in (b). (d) From left to right are images before the reaction, after the reaction, treated with 100 mM NaBH4 for 15 minutes and further treated with 500 mM NaBH4 for 15 minutes. (e) The corresponding scattering intensities of the four situations in (d).
