Graphene Quantum Dots for Radiotherapy

ACS Applied Materials & Interfaces, 2018
Radiation therapy is a kind of tumor treatment that has been widely employed in clinics, but its therapeutic effect is largely hampered by various factors. Currently, considerable efforts are being made in the search for effective and safe radiosensitizers. A nano-radiosensitizer is an ideal choice for improving the effects of tumor radiotherapy due to

Graphene quantum dots redefine nanobiomedicine

Materials Science and Engineering: C, 2020
Carbon-based nanomaterials have established a prime position as drug delivery carriers. It is very interesting to see that a carbon nanostructure could be used as a drug too, instead of its regular application as a drug delivery carrier. In this aspect, graphene quantum dots (GQDs) are now in the spotlight.

Transmission and scarring in graphene quantum dots

Journal of Physics: Condensed Matter, 2009
We study electronic transport in quantum-dot structures made of graphene. Focusing on the rectangular dot geometry and utilizing the non-equilibrium Green's function to calculate the transmission in the tight-binding framework, we find significant fluctuations in the transmission as a function of the electron energy.
