“…Sensing has covered both environmental and health sectors, contributing to the detection and monitoring of traces of pollutants (66,67) and blood biomarkers (68)(69)(70)(71). The thin structure, large surface area, chemical modifications and quenching ability of 2D materials provide high sensitivity, durability, stability, selectivity, and conductivity for sensors and biosensors (72)(73)(74)(75)(76)(77)(78)(79)(80)(81)(82).…”

Two-dimensional (2D) materials have emerged as an important class of nanomaterials for technological innovation due to their remarkable physicochemical properties, including sheet-like morphology and minimal thickness, high surface area, tuneable chemical composition, and surface functionalization. These materials are being proposed for new applications in energy, health, and the environment; these are all strategic society sectors toward sustainable development. Specifically, 2D materials for nano-imaging have shown exciting opportunities in in vitro and in vivo models, providing novel molecular imaging techniques such as computed tomography, magnetic resonance imaging, fluorescence and luminescence optical imaging and others. Therefore, given the growing interest in 2D materials, it is mandatory to evaluate their impact on the immune system in a broader sense, because it is responsible for detecting and eliminating foreign agents in living organisms. This mini-review presents an overview on the frontier of research involving 2D materials applications, nano-imaging and their immunosafety aspects. Finally, we highlight the importance of nanoinformatics approaches and computational modeling for a deeper understanding of the links between nanomaterial physicochemical properties and biological responses (immunotoxicity/biocompatibility) towards enabling immunosafety-by-design 2D materials.

“…One of the prominent features that has led to much attention being paid to the nanomaterials is believed to be their high surface-to-volume ratio. Nanoparticles can have high potential to absorb contaminants from polluted environments due to this eminent feature and other favorable properties (Noronha;. The use of carbon nanotubes today has been widely investigated as a promising solution for the removal of various types of pollutants due to their high surface area, small, hollow and layered structures, flexibility and high elasticity (Xiang;.…”

Antibiotics along with their metabolites due to their toxicity and low biodegradability have adverse effects to human and animal health. This work can help to monitor and elimination of the residue of the cloxacillin (Clox) antibiotics in two ways: the first part involves design and fabrication of a new electrochemical nanosensor based on a screen-printed carbon electrode modified with gold nanourchin and graphene oxide for detection and determination of Clox in aqueous media. The second part focuses on the preparation of carbon nanocomposites modified with multi-walled carbon nanotubes (MWCNT/CC) as adsorbent for the removal of Clox from aqueous medium. The MWCNT/CC nanocomposites were made using sol-gel process and then the efficiency of the antibiotic removal was assessed by the designed nanosensor. In Clox removal experiments, the effect of independent variables including pH, exposure time, extent of MWCNTs and amount of adsorbent on the removal of antibiotic as a dependent variable was investigated using response surface methodology. The morphological and physical properties of the suggested adsorbent were explored. The maximum efficiency of Clox removal (97%) was achieved in conditions of using 1.52 g/L of the adsorbent fabricated by 2.9 wt. % of MWCNTs in 0.1 M phosphate buffer solution at pH of 5.0 during 75 minutes. The highest adsorption capacity of the MWCNT/CC was 296 mg/g at optimal conditions.
