The morphologies of self-assembled
amphiphiles before and after the interaction of HAuCl4 were
obtained from SEM (Hitachi S-3000N, Japan) and FESEM (Hitachi High
Tech SU6600), and high-resolution transmission electron microscopic
(HRTEM) images were recorded with a JEOL JEM 2100 microscope equipped
with a Gatan imaging filter. Samples for SEM and FESEM imaging were
prepared by casting 5–10 μL of amphiphile-templated AuNPs
on aluminum foils and then were dried at ambient temperature. The
HRTEM analysis was conducted by placing a drop of the NP solution
on a carbon-coated copper grid and followed by solvent evaporation
under ambient temperature. The average size of the NPs was analyzed
using ImageJ software.
For optical microscopic studies, the
glass slides were initially washed with alcohol and then with double-distilled
water and were dried in a hot air oven. The amphiphile-templated AuNPs
were dropped onto a glass slide using a micropipette and were allowed
for slow evaporation at ambient temperature. The resulting dried drops
were imaged on a Leica DM 2500 optical microscope.
