Gold nanobipyramids (Au NBPs) are nanostructures with narrow plasmon resonances, which make them suitable for sensing applications. In the present work, Au NBPs of different aspect ratios were synthesized using a seed-mediated growth method by tuning the seed volume. The usual capping molecule CTAB was replaced by 11-mercaptoundecanoic acid (11-MUA), and the nanoparticle stability was studied. The 11-MUA capped NBPs were found to be more stable compared to the CTAB capped NBPs. The bulk refractive index sensitivities of all Au NBPs of CTAB and 11-MUA capped NBPs were measured using sucrose solutions of different weight percentages (0–30%). 11-MUA capped Au NBPs showed better refractive index sensitivity than CTAB capped Au NBPs. The NBPs of aspect ratio 3 showed maximum sensitivity of 353 nm/RIU.
