Abstract
- A three‐dimensional (3D) plasmonic substrate was developed using gold nanorods (GNRs) onto a tapered fiber surface using optical tweezing. To determine the efficacy of the substrate, Raman spectra of two toxic chemicals Rhodamine 6G (R6G) and Crystal Violet (CV) were studied. The "dip and dry" method was used to adsorb the chemicals along the tapered fiber length. The minimum concentration detected for CV and R6G was 10−12 M. We have reported the characteristics and unique features of the manufactured substrate. [ABSTRACT FROM AUTHOR]
