Autor: Severino S. Monte-Filho, Stefani I.E. Andrade, Marcelo B. Lima, Mario C.U. Araujo

Publikováno v: Journal of Pharmaceutical Analysis, Vol 9, Iss 3, Pp 209-216 (2019)

In this work, lemon and onion biomasses commonly found in street markets are for the first time used to develop a facile, fast and low-cost one-step microwave-assisted carbonization method for synthesis of highly fluorescent carbon dots (CDs). The st
