“…This is related to the enhancement of intracellular ROS levels induced by these mixtures. Additionally, Wang et al addressed that the synergistic cytotoxicity induced by graphene nanoplatelets (GNs) or reduced graphene oxide (rGO) and metal-based nZrO 2 to Chlorella pyrenoidosa and the mechanism underlying this synergistic action were associated with the induction of intracellular oxidative stress and cellular membrane functional changes by the carbon–metal-based mixtures. In addition, the effects of mixtures of nAg and nZnO on Daphnia magna were synergistic, while their respective salts (AgNO 3 and ZnCl 2 ) behaved antagonistically .…”

The rapid development of nanomaterials (NMs) and the emergence of new multicomponent NMs will inevitably lead to simultaneous exposure of organisms to multiple engineered nanoparticles (ENPs) at varying exposure levels. Understanding the joint impacts of multiple ENPs and predicting the toxicity of mixtures of ENPs are therefore evidently of importance. We reviewed the toxicity of mixtures of ENPs to a variety of different species, covering algae, bacteria, daphnia, fish, fungi, insects, and plants. Most studies used the independent-action (IA)-based model to assess the type of joint effects. Using co-occurrence networks, it was revealed that 53% of the cases with specific joint response showed antagonistic, 25% synergistic, and 22% additive effects. The combination of nCuO and nZnO exhibited the strongest interactions in each type of joint interaction. Compared with other species, plants exposed to multiple ENPs were more likely to experience antagonistic effects. The main factors influencing the joint response type of the mixtures were (1) the chemical composition of individual components in mixtures, (2) the stability of suspensions of mixed ENPs, (3) the type and trophic level of the individual organisms tested, (4) the biological level of organization (population, communities, ecosystems), (5) the exposure concentrations and time, (6) the endpoint of toxicity, and (7) the abiotic field conditions (e.g., pH, ionic strength, natural organic matter). This knowledge is critical in developing efficient strategies for the assessment of the hazards induced by combined exposure to multiple ENPs in complex environments. In addition, this knowledge of the joint effects of multiple ENPs assists in the effective prediction of hybrid NMs.

“…The combined action of hypochlorite and visible‐light‐transformed GO reduces the photosynthesis of chlorella, thus inhibiting its growth and reproduction (Wang et al, 2020). Similarly, binary mixtures of RGO and (ZrO2) n , combinations of GO and ionic liquids, GO after 8 days of sunlight conversion, and graphene and its derivatives for adsorption macronutrient in water have been all proven to induce oxidative stress in algae cells, resulting in membrane damage, nutrient depletion, and eventually inhibiting the algae cells' growth (Wang et al, 2017; Wang, Zhang, et al, 2021; Zhao et al, 2020). In addition, the combination of graphene and its derivatives with heavy metals and pesticides has toxic effects on the normal metabolism, movement, development, and reproduction of aquatic animals (including vertebrates and invertebrates) (Britto et al, 2020; Chen et al, 2021; de Medeiros et al, 2020; Li et al, 2021).…”

The purpose of this paper is to explore the current research status, hot topics, and future prospects in the field of graphene and its derivatives toxicity. In the article, the Web of Science Core Collection database was used as the data source, and the Cite-Space and VOSviewer were used to conduct a visual analysis of the last 10 years of research on graphene and its derivatives toxicity. A total of 8573 articles were included, and we analyzed the literature characteristics of the research results in the field of graphene and its derivatives toxicity, as well as the distribution of authors and co-cited authors; the distribution of countries and institutions; the situation of co-cited references; and the distribution of journals and categories. The most prolific countries, institutions, journals, and authors are China, the Chinese Academy of Sciences, RSC Advances, and Wang, Dayong, respectively. The co-cited author with the most citations was Akhavan, Omid. The five research hotspot keywords in the field of graphene and its derivatives toxicity were "nanomaterials," "exposure," "biocompatibility," "adsorption," and "detection." Frontier topics were "facile synthesis," "antibacterial activity," and "carbon dots." Our study provides perspectives for the study of graphene and its derivatives toxicity and yields valuable information and suggestions for the development of graphene and its derivatives toxicity research in the future.

“…Notwithstanding the high electrical conductivity and ease of surface modification of CNTs and graphene, using these nanomaterials in direct contact with human tissue has faced many challenges (Saleemi et al, 2021; Z. Wang et al, 2021). By reviewing the experimental endeavors, it can be deduced that the reduction in the probe functionality over time and the appearance of glial scarring in the implanted tissue are the most cited problems (Dong et al, 2021; Spencer et al, 2017; Zou et al, 2021).…”

As scientists discovered that raw neurological signals could translate into bioelectric information, brain–machine interfaces (BMI) for experimental and clinical studies have experienced massive growth. Developing suitable materials for bioelectronic devices to be used for real‐time recording and data digitalizing has three important necessitates which should be covered. Biocompatibility, electrical conductivity, and having mechanical properties similar to soft brain tissue to decrease mechanical mismatch should be adopted for all materials. In this review, inorganic nanoparticles and intrinsically conducting polymers are discussed to impart electrical conductivity to systems, where soft materials such as hydrogels can offer reliable mechanical properties and a biocompatible substrate. Interpenetrating hydrogel networks offer more mechanical stability and provide a path for incorporating polymers with desired properties into one strong network. Promising fabrication methods, like electrospinning and additive manufacturing, allow scientists to customize designs for each application and reach the maximum potential for the system. In the near future, it is desired to fabricate biohybrid conducting polymer‐based interfaces loaded with cells, giving the opportunity for simultaneous stimulation and regeneration. Developing multi‐modal BMIs, Using artificial intelligence and machine learning to design advanced materials are among the future goals for this field.This article is categorized under: Therapeutic Approaches and Drug Discovery > Nanomedicine for Neurological Disease
