In addition, the synthetic procedures typically involve a low lignin concentration and a higher temperature compared to our system. Other works have attempted to upscale the production of lignin doped silver nanoparticles using an ionic liquid as a capping agent. Compared to more complicated and time-consuming synthesis, our procedure in aqueous dispersion at room temperature requires only three hours for completion. Furthermore, although our colloidal sensor could not challenge the low detection limit offered by electrochemical materials, our material is scalable and does not require conductive carbon materials.
