DNA damage induced by multiwalled carbon nanotubes in mouse embryonic stem cells.
The results suggest that careful scrutiny of the genotoxicity of nanomaterials is needed even for those materials, like multiwalled carbon nanotubes, that have been previously demonstrated to have limited or no toxicity at the cellular level.
DNA damage in embryonic stem cells caused by nanodiamonds.
It is shown that incubation of embryonic stem cells with NDs led to slightly increased expression of DNA repair proteins, such as p53 and MOGG-1, which should have important implications for future applications of NDs in biological applications.
Liquid Marbles Based on Magnetic Upconversion Nanoparticles as Magnetically and Optically Responsive Miniature Reactors for Photocatalysis and Photodynamic Therapy.
This work reports the first development of liquid marbles coated with magnetic lanthanide-doped upconversion nanoparticles (UCNPs) that can convert near-infrared light into visible light and shows great promise for liquid marbled based on UCNPs to be used in a large variety of potential applications, such as photodynamic therapy for accelerated drug screening, magnetically guided controlled drug delivery and release, and multifunctional actuation.
Can graphene quantum dots cause DNA damage in cells?
The GQD-induced release of reactive oxygen species (ROS) was demonstrated to be responsible for the observed DNA damage and should have important implications for future applications of GQDs in biological systems.
Two-Dimensional Fully Conjugated Polymeric Photosensitizers for Advanced Photodynamic Therapy
Photodynamic therapy (PDT) is attractive for treatment of various cancers, with a high selectivity, minimal long-term effect, and excellent cosmetic appeal. Well water-dispersive photosensitizers…

Assessment of Human Lung Macrophages After Exposure to Multi-Walled Carbon Nanotubes. Part 1. Cytotoxicity
It is demonstrated that multi-walled carbon nanotubes can accumulate in human lung macrophage cells to different degrees based on their surface chemistry, and MWNT-COOH reduces cell viability in a dose-dependent manner under these experimental conditions.
Recent Advances in Carbon‐Based Metal‐Free Electrocatalysts
A critical overview of the very recent advances in this rapidly developing field during the last couple of years is presented.
