Figure 3

(a) Reflectance mode optical images of AgNWs incubated with LLF at pH 7 (i-iii) and pH 5 (iv-vi), for 1 hour (i, iv), 24 hours (ii, v) and 7 days (iii, vi). (b) Reflectance mode optical images of AgNWs incubated at pH 7 (i-v) and pH 5 buffers (vi-x), in the absence (i, ii, vi and vii) and presence of DPPC (iii and viii), Curosurf® (iv and ix) and LA (v and x). (b) Reflectance mode optical images of AgNWs incubated with Curosurf® and SA at pH 7 (i-iii) and pH 5 (iv-vi), for 1 hour (i, iv), 24 hours (ii, v) and 7 days (iii, vi). (c) A BFTEM image of AgNWs incubated at pH 5 for 14 days. (d) A STEM image and (e) a STEM/EDX spectrum from the area marked in (d) of AgNWs incubated with SA for 24 hours.
