Figure 3

(a) Schematic illustration of micropatterning with poly(IPAAm) and Ag nanocluster in a hydrogel matrix, prepared with DMAAm/TiNSs/Laponite (8.0/3.0/3.0 wt%), upon light exposure (λ>260 nm) through a patterned photomask (500 × 500 μm2 open squares). (b) Pictures of a micropatterned hydrogel with poly(IPAAm) at 40 and 25 °C. Scale bar, 500 μm. (c) A picture of a micropatterned hydrogel with Ag nanocluster at 25 °C. Scale bar, 500 μm. (d) Change in surface plasmonic absorbance (500 nm) with light exposure time of Ag nanocluster micropatterned in the hydrogel.
