Abstract

We report a rapid one-pot microwave-assisted strategy toward the synchronous preparation of two nano-biomaterials with different scales in 10 min: highly monodisperse and stable lignin nanoparticles with functional groups, and nitrogen-doped carbon nanodots with bright purple photoluminescence. The as-prepared biomaterials show great potential for application.
