Congratulations to Josh, Elliott and Keith on their new paper in ACS Nano (https://doi.org/10.1021/acsnano.2c11240) with a team led by Han Young Woo from Korea University in Seoul. Han Young’s team came out for a research visit a few years and this has culminated in this work. The paper describes the use of polymer dots doped with strong Raman scattering dyes. One advantage is the suppression of emission from the dyes that permits the resonance Raman signal to be observed. Using slight modifications to the truxene-based dyes it is possible to modify the resonant electronic transition and the Raman signature. This allows for a bar-coding approach to sensing as similar materials can be programmed to give differing spectral responses.
