Graphene quantum dots (GQDs) are nano-sized fragments of graphene sheets, with great potential for applications in optics, electrochemistry, and biomedicine, including drug delivery. In this study, two types of GQDs were investigated: green-emitting (G-GQD) and blue-emitting (B-GQD) and their genoto ...

Genotoxic effects of graphene quantum dots in an advanced in vitro human hepatic 3D model
Irma Durmišević, Anja Haverić, Sonja Žabkar, Alja Štern, Bojana Žegura
Raziskovalni podatki
Oznake: nanomaterials;graphene quantum dots;HepG2 spheroids;toxicity;
Graphene quantum dots (GQDs) are nanoscale carbon-based materials characterized by a tunable bandgap and unique physicochemical features. Typically composed of only a few atomic layers and measuring under 10 nm in lateral dimension, they show excellent biocompatibility and low toxicity, making them ...

In vitro toxicity assessment of graphene quantum dots using a 3D HepG2 model
Irma Durmišević, Anja Haverić, Sonja Žabkar, Alja Štraser, Katja Kološa, Petra Jenuš, Iza Rozman, Bojana Žegura
Izvirni znanstveni članek
Oznake: nanomaterials;graphene quantum dots;HepG2 spheroids;toxicity;
In the present study, two types of graphene quantum dots (GQDs) were investigated: green-emitting (G-GQDs) and blue-emitting (B-GQDs). Physicochemical characterisation was performed using transmission electron microscopy (TEM), zeta potential, and hydrodynamic radius measurements to evaluate the mor ...
