Green synthesis of graphene quantum dots from Opuntia sp. extract and their application in phytic acid detection

Phytic acid and phytate anions are among the principal reserves of phosphorus. A few methods have been used for their detection, but these methods require harsh conditions. In this work, graphene quantum dots are successfully synthesized by Opuntia sp. extract through a pyrolysis microwave treatment. This green synthesis method allows us to controllably obtain nanostructures with excellent dispersion and a narrow size distribution to use for...
