Figure 4

Optical image of the nanosystems (gold nanostructures and CurNem) and the microgels containing them. Upper panels: (a) GNS (5.4 nM of nanospheres); (b) CurNem (1.5 mM of curcumin) and (c) Microgels (≈220 µm) containing GNS (1.35 nM of nanospheres) and CurNem (375 µM of curcumin). Lower panels: (d) GNR (0.2 nM of nanorods); (e) CurNem (1.5 mM of curcumin) and (f) Microgels (≈220 µm) containing GNR (0.05 nM of nanorods) and CurNem (375 µM of curcumin).
