摘要 To repair the blood–brain barrier(BBB)after traumatic brain injury(TBI)remains a multidisciplinary challenge.No first-line drugs are available.Here,we reported a novel and non-toxic functional negative-charged carbon dots(CDs)generated from green Semen pruni persicae and Carthamus tinctorius L.(TH-CDs)through a hydrothermal synthesis without any organic solvent.The surface of TH-CDs retained part functional groups of active pharmacophores from both drugs.TH-CDs could improve the neurological function,brain edema,neuronal damage,and the BBB permeability by tail vein injection of mice models without systemic toxicity.Furthermore,higher expression of tight junction proteins claudin 5 and ZO-1 was observed after TH-CDs administration,which may be due to the electrostatic interaction between TH-CDs and claudin 5.Our study highlights an inexpensive,green,non-toxic,and intravenous functional TH-CD,which represents a potential TBI treatment strategy.
