Physicochemical characterization of AgNWs incubated in various cell culture media, for 1h at 37 °C: (a–c) DCCM-1, (d) DMEM and (e) RPMI-1640. (a) A representative BF-TEM image of the AgNWs incubated in DCCM-1 medium, showing the formation of crystallites on the surface of the AgNWs. The inset is a SAED pattern taken from the circled area (aperture size ~130 nm). (b) An HRTEM image collected from the boxed area in Fig. 2a reveals that the crystallites have a different crystal structure than the original AgNWs. The insets are FFT patterns taken from the two boxed areas. HAADF-STEM image (c-top) taken from the same area as Fig. 2a. STEM-EDX spectra were collected from the circled area (c-bottom). (d–e) HAADF-STEM images (top) and EDX spectra (bottom) of AgNWs incubated in DMEM and RPMI-1640 cell media, respectively.
