Biological assays used to assess the potential toxicity of nanoparticles, from cell viability to mutations are described in this section, and designed specifically for readers who may not be too familiar with biological assay protocols. An overview of graphene and graphene oxide toxicity in cell and...
Liao et al [140] found that the toxicity of graphene and graphene oxide depended on whether or not aggregation occurred and on the mode of interaction with cells (i.e., suspension versus adherent cell types). Ekstrand-Hammarström et al [141] determined that crystal structure, surface area...

This was explained by a high capacity of graphene oxide NPs for adsorbing protein molecules, which cover the NP surface, thereby changing the shape of the NPs and partly preventing the damage of cell membranes [75]. Nanoparticle Chemical Composition and Toxicity Although the toxicity of NPs ...
Meanwhile, recent theoretical studies have also revealed graphene's (including graphene oxide) influence on the integrity of cell membranes27–30, as well as protein structures23,25. Based on these findings from both experiment and theory on the fundamental mechanisms, various strategies have been ...
GoldMag nanoparticles (GMNPs) possess the properties of colloid gold and superparamagnetic iron oxide nanoparticles, which make them useful for delivery, separation and molecular imaging. However, because of the nanometer effect, GMNPs are highly toxic. Thus, the biosafety of GMNPs should be fully...
Our results point out implications for in vitro studies of graphene oxide materials concerning the effective dose delivered to cells and corona bioactivity. Finally, we demonstrated the importance of integrating conventional and modern techniques thoroughly to understand the GO-FBS complexes towards more ...
