“…The above substances combine or react with graphene and its derivatives, resulting in changes in the particle size, surface charge, surface modification, and other physical and chemical properties of graphene and its derivatives, and also affect the migration, transformation, adsorption, aggregation, deposition, degradation, or redox reactions in the environment of graphene and its derivatives (Ding et al, 2022). Studies have shown that ozone molecules can change the surface morphology and adsorption capacity of graphene through physical adsorption or oxidation (Ali & Tit, 2019; Choudhury et al, 2021). It should not be overlooked that sunlight may also affect the transformation of graphene and its derivatives.…”

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.

“…Interestingly, superhydrophilicity was maintained after one year. In contrast, Choudhury et al first prepared LSG and then ozonated it with a UV-ozone cleaner 82 . When LSG was exposed to an O3 atmosphere, O3 diffused favorably into the interior of the material owing to the high specific surface area and large porosity of LSG and then further reacted with carbon atoms to produce a higher content of oxygen-containing groups such as ketone groups, hydroxyl groups, and esters at the base and edges of the material 83 .…”

Sensors are widely used to acquire biological and environmental information for medical diagnosis, and health and environmental monitoring. Graphene is a promising new sensor material that has been widely used in sensor fabrication in recent years.Compared with many other existing graphene preparation methods, laser-scribed graphene (LSG) is simple, low-cost, environmentally friendly, and has good conductivity and high thermal stability, making it widely used in the sensor field. This paper summarizes existing LSG methods for sensor fabrication. Primary LSG preparation methods and their variants are introduced first, followed by a summary of LSG modification methods designed explicitly for sensor fabrication. Subsequently, ACCEPTED ARTICLE PREVIEW2 the applications of LSG in stress, bio, gas, temperature, and humidity sensors are summarized with a particular focus on multifunctional integrated sensors. Finally, the current challenges and prospects of LSG-based sensors are discussed.

“…Ion selective transistor. The recipe for the sodium ion selective transistor was adapted from Choudhury et al 107 In brief, a solution of 80 mg mL −1 of the ion selective membrane was produced by dissolving 264 mg of polyvinyl chloride (PVC) (Sigma Aldrich, high molecular weight, Selectophore grade), 530 mg (1.24 mmol) of bis(2-ethylhexyl) sebacate (DOS) (Sigma Aldrich, selectophore grade) plasticiser, 5.6 mg (5.64 µmol) of sodium ionophore X (IUPAC: 4-tert-butylcalix [4]arene-tetraacetic acid tetraethyl ester, Sigma Aldrich, selectophore grade), and 1.6 mg (3.23 µmol) of potassium tetrakis ((4-chlorophenyl)-borate) (Sigma Aldrich, selectophore grade) ion exchanger in 10 mL of tetrahydrofuran (THF) (Sigma Aldrich, selectophore grade) and shaken for 10 minutes until the solution turned translucent. A 9 : 1 dilution in THF was conducted to produce a solution of 8 mg mL −1 .…”
