Toward Plasmonic Neural Probes: SERS Detection of Neurotransmitters through Gold‐Nanoislands‐Decorated Tapered Optical Fibers with Sub‐10 nm Gaps (Adv. Mater. 11/2023)

Neurochemical Detection In article number 2200902, Di Zheng, Massimo De Vittorio, Ferruccio Pisanello, and co-workers present a surface-enhanced Raman scattering (SERS)-active probe based on a tapered optical fiber decorated with sub-10 nm-gap gold nanoislands, which is designed for neurochemical detection. Through-fiber measurements show the fabricated device can detect neurotransmitters down to the micromolar range. Cover image artwork by: Antonio Balena, Barbara Spagnolo, and Di Zheng.
