AB  - Carbon dots, which are less than 10 nm in diameter, have been widely investigated 
      because of their unique luminescence properties and potential for use in 
      bioimaging. In the present work, natural carbon dots (L-CDs) were obtained by 
      molecular aggregation, using ethanol-extracted cellulolytic enzyme lignin. The 
      whole process for the preparation of L-CDs was green and simple to operate and 
      did not use toxic chemical reagents or harsh conditions. The newly prepared L-CDs 
      emitted multicolor photoluminescence following one- and two-photon excitation. 
      The L-CDs also showed good cellular biocompatibility, which is crucial for 
      biological applications. One- and two-photon cell-imaging studies demonstrated 
      the potential of L-CDs for bioimaging.
