4‐NP conversion by a) DFNS/Au dots, (b to f) DFNS/Au nanohybrids synthesized: b) ratio: 7, c) ratio: 15, d) ratio: 30, d) ratio: 61, e) ratio: 123, and f) ratio: 246. 4‐NP conversion is calculated as follows: Conversion (%)= (1−C t C 0 −1)×100, where C t is the absorption of 4‐NP at a given reaction time, t, and C 0 is the initial absorption by 4‐NP at t=0.
