Eco-friendly synthesis of size-controllable amine-functionalized graphene quantum dots with antimycoplasma properties

Due to the low cytotoxicity and excellent biocompatibility of the obtained amine-functionalized graphenequantum dots, besides the multiwavelength imaging properties of GQDs, for the first time we find that this kind of GQD exhibits good antimycoplasma properties

Scholarcy highlights

  • Size-controllable amine-functionalized graphenequantum dots are prepared by an eco-friendly method with graphene oxide sheets, ammonia and hydrogen peroxide as starting materials
  • By atomic force microscopy characterization, we confirm that hydrogen peroxide and ammonia play a synergistic role on graphene oxide, in which the former cuts the GO into small pieces and the latter passivates the active surface to give amine-modified GQDs
  • Due to the low cytotoxicity and excellent biocompatibility of the obtained amine-functionalized GQDs, besides the multiwavelength imaging properties of GQDs, for the first time we find that this kind of GQD exhibits good antimycoplasma properties
  • Given the superior antimycoplasma effect of the graphenequantum dots and their eco-friendly mass production with low cost, these new GQDs may offer opportunities for the development of new antimycoplasma agents, extending their widespread application in biomedicine
