Figure 2. Refractive index sensitivity of AuNSs compared to AuNPs.

Figure 2.

Gaussian fits to LSPR peaks of (a) AuNPs and (b) AuNSs suspended in solutions of varying weight percent sucrose with known refractive indices. (c) Shifts in LSPR as a function of change in refractive index for AuNSs and AuNPs. AuNSs exhibited greater refractive index sensitivity (210 nm/RIU) compared to AuNPs (17.4 nm/RIU).
