N2 - In search of a biocompatible and sustainable platform for surface-enhanced Raman scattering (SERS) studies, nanorods with a high aspect ratio of coinage metals such as gold, silver, and copper augment the peak intensity, but the shelf life of metal nanoparticles is questionable. Here, we report the synthetic strategy of parallelly aligned nanorods achieved by the synergetic action of carboxyl-functionalized nanocellulose fibers (TNCF) and cetyl trimethyl ammonium bromide (CTAB) as both reducing and capping agents. The synthesized parallel nanorods shows excellent SERS enhancement down to 10−7 M concentration of methylene blue and 0.1 ppm of thiram (pesticide). Additionally, TEMPO-oxidized nanocellulose fibers-supported nanorods colloid showed excellent shelf life. Our approach using TEMPO-oxidized nanocellulose fibers-supported Au nanorods can be considered an efficient and reproducible surface-enhanced Raman scattering substrate environmental monitoring.
