“…The epoxy and carbonyl groups in GO were assigned by the peaks at 1234.76 and 1049.36 cm −1 , respectively. The presence of epoxy and carboxyl groups on the surface of GO implies that the original conjugated pi-orbital system in graphite was damaged, resulting in the formation of additional reactive sites 36 . Moreover, the FT-IR of Gel@GO-F-ZrSiO 4 @Gel nanobiosorbent reveals a number of related distinct functional groups and peaks to gelatin at 1636, 1548, and 1407 cm −1 which directly correlated to the various forms of amide bonds in gelatin, with three other unique peaks at 429, 602, and 861 cm −1 corresponding to metal–oxygen bonding of either Si–O or Zr–O in ZrSiO 4 43 .…”

“…One of the most important factors in evaluation of the removal process of organic dyes from aqueous solutions by adsorption technique is mainly related to the pH of contact solution. This factor measures the efficiency and effectiveness of Gel@GO-F-ZrSiO 4 @Gel nanobiosorbent in binding with BF dye under various conditions of protonation and deprotonation 36 . Generally, the medium pH affects the species of the target BF dye and the degree of protonation of the loaded functional groups on the surface of Gel@GO-F-ZrSiO 4 @Gel nanobiosorbent.…”

Most dye stuffs and coloring materials are mainly categorized as hazardous pollutants in water effluents due to their nature as non-biodegradable, highly toxic and extremely carcinogenic. For this reason, rapid and efficient eradication of waste dyes from wastewaters before discharging into water streams must be accomplished by an acceptable approach as adsorption technique. Therefore, the present study is aimed and devoted to synthesize a novel nanobiosorbent from three different constituents, gelatin (Gel) as a sustainable natural product, graphene oxide (GO) as an example of highly stable carbonaceous material and zirconium silicate (ZrSiO4) as an example of combined metal oxides for the formation of Gel@GO-F-ZrSiO4@Gel by using formaldehyde (F) as a cross-linkage reagent. Several characterization techniques as FT-IR were employed to identify the incorporated surface reactive Functionalities in Gel@GO-F-ZrSiO4@Gel as –OH, =NH, –NH2, –COOH and C=O, etc. The morphology for particle shape and size of Gel@GO-F-ZrSiO4@Gel were confirmed from the SEM and TEM analyses providing 15.75- 32.79 nm. The surface area was determined by the BET and found to correspond to 219.46 m2 g-1. Biosorptive removal of basic fuchsin (BF) pollutant as an example of a widely applicable dye in various activities was monitored and optimized under the influence of pH (2–10), reaction time (1–30 min), initial BF pollutant concentration (5–100 mg L−1), nanobiosorbent dosage (5–60 mg), temperature (30–60 °C) and interfering ions. The maximum biosorptive removal values of BF dye were established as 96.0 and 95.2% using 5 and 10 mg L−1, respectively at the recommended pH 7 condition. The Thermodynamic parameters demonstrated that the BF dye adsorption onto Gel@GO-F-ZrSiO4@Gel was taken place via spontaneous and endothermic reaction. Chemisorption is the predominant adsorption mechanism by forming multilayers upon nonhomogeneous surface in accordance with Freundlich model hypothesis. The applicability of the optimized Gel@GO-F-ZrSiO4@Gel in biosorptive removal of BF pollutant from real water sample was successfully accomplished by the batch technique. Thus, this study clearly shows that Gel@GO-F-ZrSiO4@Gel exhibited significant influences on remediation of industrial effluents containing BF pollutant with superior efficiency.

Graphic abstract Over the past few years, there has been a growing potential use of graphene and its derivatives in several biomedical areas, such as drug delivery systems, biosensors, and imaging systems, especially for having excellent optical, electronic, thermal, and mechanical properties. Therefore, nanomaterials in the graphene family have shown promising results in several areas of science. The different physicochemical properties of graphene and its derivatives guide its biocompatibility and toxicity. Hence, further studies to explain the interactions of these nanomaterials with biological systems are fundamental. This review has shown the applicability of the graphene family in several biomedical modalities, with particular attention for cancer therapy and diagnosis, as a potent theranostic. This ability is derivative from the considerable number of forms that the graphene family can assume. The graphene-based materials biodistribution profile, clearance, toxicity, and cytotoxicity, interacting with biological systems, are discussed here, focusing on its synthesis methodology, physicochemical properties, and production quality. Despite the growing increase in the bioavailability and toxicity studies of graphene and its derivatives, there is still much to be unveiled to develop safe and effective formulations.

Design and assembly of novel nanocomposites with multi‐purpose activities including efficient adsorption behavior toward different pollutants and microbial growth inhibition of various active biological species is a challenging aspect. Therefore, the current study is devoted to fabricating a novel nanocomposite of mixed metal oxides (ZrO2 and SiO2) with magnetite (Fe3O4) and cationic surfactants (cetyltrimethyl ammonium bromide [CTAB] and dodecyltrimethyl ammonium bromide [DoTAB]) via a solvent free microwave methodology to yield ZrSiO4 NPs‐CTAB@Fe3O4 NPs‐DoTAB. The as‐prepared nanocomposite was characterized by SEM to confirm the existence of homogeneous particles (~32.45 nm). The chemical structure of nanocomposite was also confirmed from the energy dispersive X‐ray spectroscopy (EDX), Fourier‐transform infrared spectroscopy (FTIR), and X‐ray diffraction (XRD) analyses. The surface area of this nanocomposite was also determined by the Brunauer‐ Emmett‐ Teller (BET) method and found to correspond to 6.319 m2 g−1. Remediation of Azorubine E122 food dye was optimized in the presence of a number of controlling parameters. The maximum adsorption capacity was characterized as 66.55 mg g−1 using 50 mg nanocomposite at 20 min. Kinetics and isotherm modeling evaluations referred to the best fitting with pseudo‐second order and Freundlich model, respectively. The antibacterial activity of ZrSiO4 NPs‐CTAB@Fe3O4 NPs‐DoTAB nanocomposite was assessed against Escherichia coli ATCC® 25922™ and Staphylococcus aureus ATCC® 25923™, and the collected data proved efficient growth inhibition (p < 0.05) at considerably low concentrations of the investigated nanocomposite. Therefore, the evaluated ZrSiO4 NPs‐CTAB@Fe3O4 NPs‐DoTAB nanocomposite was concluded to afford excellent antibacterial activity and efficient magnetic removal behavior of organic dyes. Hence, it is recommended as a talented material for purification of water resources containing multi‐chemical and biological pollutants as well. Finally, this study is expected to open new prospects for manufacturing other new nanocomposites with the aim of future applications in the removal of different chemical pollutants as well as viruses and bacteria.
