Synthesis of Functionalized Carboxylated Graphene Oxide for the Remediation of Pb and Cr Contaminated Water. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2022; 19:ijerph191710610.

Abstract
With the growing scarcity of water, the remediation of water polluted with heavy metals is the need of hour. The present research work is aimed to address this problem by adsorbing heavy metals ions (Pb (II) and Cr (VI)) on modified graphene oxide having an excess of carboxylic acid groups. For this, graphene oxide (GO) was modified with chloroacetic acid to produce carboxylated graphene oxide (GO-COOH). The successful synthesis of graphene oxide and its modification has been confirmed using Fourier transform infrared spectroscopy (FT-IR), Raman spectroscopy, X-ray Diffraction (XRD), Scanning electron microscopy (SEM), Energy Dispersive X-ray Analysis (EDX) and Transmission electron microscopy (TEM). The increase in surface area of graphene oxide after treatment with chloroacetic acid characterized by BET indicated its successful modification. A batch experiment was conducted to optimize the different factors affecting adsorption of both heavy metals on GO-COOH. After functionalization, we achieved maximum adsorption capacities of 588.23 mg g-1 and 370.37 mg g-1 for Pb and Cr, respectively, by GO-COOH which were high compared to the previously reported adsorbents of this kind. The Langmuir model (R2 = 0.998) and Pseudo-second-order kinetic model (R2 = 0.999) confirmed the monolayer adsorption of Pb and Cr on GO-COOH and the chemisorption as the dominant process governing adsorption mechanism. The present work shows that the carboxylation of GO can enhance its adsorption capacity efficiently and may be applicable for the treatment of wastewater.

Abstract
Tri-nanocomposite of gelatin, gum arabic functionalized onto graphene oxide. Loading of anticancer doxorubicin onto the tri-nanocomposite via green biosynthesis. High drug loading from loaded composite, with targeted delivery to cancerous cells. High proliferative inhibition of drug loaded composite on A549 lung carcinoma. Minimal toxicity of drug loaded composite on normal WI-38 lung fibroblast.
Tri-nanocomposite system of biocompatible polymers (gelatin/gum arabic) functionalized onto graphene-oxide nanosheets for controlling the release of an anticancer, doxorubicin (DOX), was fabricated via green-biosynthesis. Biocompatibility and nano-size stability of the tri-nanocomposite was characterized by SEM, TEM, FTIR, XRD, and zeta-potential. Loading-efficiency, release-behavior and cytotoxic-activity of DOX-loaded-composite in WI-38 normal-lung-fibroblast and A549 lung-carcinoma cells were investigated. High DOX-loading (at pH 9.5), with pH-sensitive release from loaded-composite was achieved, with 25% and 77% DOX released, at physiological pH 7.4 and cancerous pH 5.3, respectively. Stability of tri-nanocomposite system was confirmed over 3-months storage at accelerated conditions, as presented by FTIR, XRD, TEM, zeta-potential and in-vitro release assays. High proliferative inhibitory effect of DOX loaded-composite, on A549-cells, with minimal toxicity on WI-38-cells, with IC50 values of 51.9 ± 0.46 and 185±1.08 µg/mL, against A549 and WI-38, respectively. Proposed tri-nanocomposite offers a novel combination of gelatin/gum arabic with graphene-oxide for targeted drug-delivery and efficient anti-cancer therapy.

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.

Abstract
Photoelectrocatalytic technology has proven to be an efficient way of degrading organic contaminants, including dyes. Graphene (GR) -based catalysts have been frequently used in photoelectrocatalysis, due to their excellent catalytic performances. In this work, the GR/beta-cyclodextrin (GR/β-CD) composite was prepared and used for a widely used triphenylmethane dye (bromophenol blue, BPB) photoelectrocatalytic degradation. The results indicated that the degradation of the prepared GR/β-CD composite for BPB was effective with the combination of external bias voltage and simulated sunlight irradiation. Under optimum conditions, the BPB (10 mg L−1) was completely eliminated by GR/β-CD composite within 120 min. ˙O2− played a prominent role in the BPB photoelectrocatalytic degradation. The time required for the removal of BPB in water to reach 100% can be reduced to 30 min with the presence of Cl−, owing to the generation of ˙Cl. Moreover, the toxicity of the degraded system with Cl−, predicted by the QSAR (Quantitative Structure–Activity Relationship) model in ECOSAR (Ecological Structure–Activity Relationships) program, was weaker than that without Cl−. The prepared GR/β-CD composite revealed great advantages in photoelectrocatalytic degradation of organic pollutants due to its metal-free, low cost, simplicity, and efficient performance. This work provided new insight into the efficient and safe degradation of organic pollutants in wastewaters. O2˙− played a crucial role in the photoelectrocatalytic degradation of BPB by the prepared GR/β-CD. Cl− marginally promoted the degradation of BPB and chlorinated intermediates were generated.![]()

Abstract
The ability of carbon-based nanomaterials (CNM) to interact with a variety of pharmaceutical drugs can be exploited in many applications. In particular, they have been studied both as carriers for in vivo drug delivery and as sorbents for the treatment of water polluted by pharmaceuticals. In recent years, the large number of experimental studies was also assisted by computational work as a tool to provide understanding at molecular level of structural and thermodynamic aspects of adsorption processes. Quantum mechanical methods, especially based on density functional theory (DFT) and classical molecular dynamics (MD) simulations were mainly applied to study adsorption/release of various drugs. This review aims to compare results obtained by theory and experiments, focusing on the adsorption of three classes of compounds: (i) simple organic model molecules; (ii) antimicrobials; (iii) cytostatics. Generally, a good agreement between experimental data (e.g. energies of adsorption, spectroscopic properties, adsorption isotherms, type of interactions, emerged from this review) and theoretical results can be reached, provided that a selection of the correct level of theory is performed. Computational studies are shown to be a valuable tool for investigating such systems and ultimately provide useful insights to guide CNMs materials development and design.

Abstract
Graphene oxide (GO) was first modified to amine functionalized GO (AGO) and acts as a cationic polyelectrolyte. Chitosan (CS) was conjugated with folic acid (FA) through N, N´ -Dicyclohexylcarbodiimide coupling to form FA-CS. After this, itaconic acid and acrylic acid monomers are grafted to the hydroxyl group of CS using ethyleneglycol dimethacrylate as cross linker and potassium peroxydisulfate as an initiator to generate -COOH functional groups and forming chemically modified chitosan (CMCS). Further doxorubicin (DOX) loaded into the FA-CMCS/AGO through π-π stacking interactions. The resulting nanocomposite was characterized by FTIR, SEM, TEM, Raman, AFM, DLS and ZP. The drug loading capacity was as high as 95.0% and the drug release rate at pH 5.3 was significantly higher than that under physiological conditions of pH 7.4. Cell viability of L929, HeLa and MCF7 cells was studied. The studies suggest the drug carrier has potential clinical applications for anticancer drug delivery.

Abstract
In this paper, a novel kind of zwitterion modified graphene oxide (GO) for promoting stability and reducing aggregation of GO as a drug carrier was proposed and demonstrated. Specifically, the GO was functionalized with a kind of zwitterion based silane, 3-(dimethyl(3-(trimethoxysilyl)propyl)-ammonio)propane-1-sulfonate (SBS). After zwitterion modification, the SBS functionalized GO (GO-SB) shows significantly enhanced stability in both serum-free and serum-containing solution, especially after loading doxorubicin hydrochloride (DOX). According to drug release profiles, the drug-loaded GO-SB exhibits thermosensitive and sustained release behavior. Meanwhile, in vitro studies show that the DOX loaded GO-SB could be easily internalized by HepG2 cells and exhibit obvious cytotoxicity on the cells. And, in vivo studies demonstrate that the GO-SB drug carrier is capable of being taken by the larvae of zebrafish and can be eliminated from the body within several days.

Abstract
A novel drug carrier is constructed by compositing hydrophilic hydroxypropyl-β-cyclodextrins (HP-β-CD) and carboxylated graphene nanomaterial (GO-COOH). Fourier transform infrared spectroscopy confirms that the two materials are successfully combined via chemical bonds. Further, a crosslinking agent of glutaraldehyde is applied to fabricate composite GO-COO-HP-β-CD nanospheres, as demonstrated by an atomic force microscope. Dexamethasone (DEX) is selected as the model drug, and the drug loading efficiency and water solubility of the nanospheres greatly increased. Additionally, the achieved DEX/nanosphere inclusion complex exhibits better heat resistance compared with pure DEX, which is a desired property for drug processing. More importantly, different models are applied to different releasing durations to investigate in detail the release profile of DEX. The best fitting release kinetics model is given to reveal the release mechanism of the drug delivery system. The highest hemolysis rate of the DEX/nanosphere inclusion is 0.44%, far lower than the standard of 5% delivered by the American Society for Testing and Materials, ensuring its safety in practical applications. Meanwhile, recalcification tests indicate that DEX/nanosphere retains the normal blood coagulation function. In vitro cytotoxicity tests of the inclusion demonstrate that the nanospheres have no toxicity and are qualified for intravenous applications with good blood compatibility. Finally, the bioactivity of DEX after release from the carriers is investigated. Results corroborate that the drug anti-inflammation efficacy is not affected and that the biomedical function can be well retained. The engineered controlled drug release system represents a promising formulation platform for a broad range of therapeutic medicine in pharmaceutical technology.

Abstract
BACKGROUND The success of gene therapy is mostly dependent on the development of gene carrier. Graphene oxide (GO) possesses excellent aqueous solubility and biocompatibility, which is important for its biochemical and medical applications. Our previous work proved that GO can deliver siRNA into cells efficiently and downregulate the expression of desired protein. METHODS In this study, a novel delivery carrier, GO-R8/anti-HER2 (GRH), was developed by conjugating octaarginine (R8) and anti-HER2 antibody with GO as a tumor active-targeting vector for survivin-siRNA delivery. RESULTS GRH/survivin-siRNA formed nanoglobes of 195±10 nm in diameter. Real-time polymerase chain reaction analysis revealed that survivin messenger RNA expression showed a 42.4%±2.69% knockdown. The expression of survivin protein was downregulated to 50.86%±2.94% in enzyme-linked immunosorbent assay. In MTT tests, GRH exhibited no testable cytotoxicity. In vivo, GRH/survivin-siRNA showed gene silencing and inhibition of tumor growth. CONCLUSION The in vitro and in vivo results consistently demonstrated that GRH/survivin-siRNA has potential to be an efficient gene silencing carrier for siRNA delivery in cancer therapy.

Abstract
The introduction of cyclodextrin species to graphene-family materials (GFMs) constitutes an important area of research, especially in terms of the development of applied nanoscience. The chemistry of cyclodextrins is the so-called host-guest chemistry, which has impacted on many fields of research, including catalysis, electrochemistry and nanomedicine. Cyclodextrins are water-soluble and biocompatible supramolecules, and therefore they may introduce new interesting properties to GFMs and may enhance the physicochemical/biological features of native GFMs. The reported methods for the conjugation of cyclodextrins to GFMs utilize either covalent or non-covalent approaches. The recent progress in the applications of GFMs functionalized with cyclodextrins, with the respect to the chemistry and features of these conjugates, is discussed. Special consideration is also given to the recent developments in (i) nanomedicine, (ii) electrochemistry, (iii) adsorption and (iv) catalysis. Examples of these materials are discussed in this work, together with the future outlook on the impact of GFM-cyclodextrin conjugates in the development of applied nanoscience.

Abstract
In this work, the modification of graphene oxides (GOs) have been done with hydrophilic and biodegradable polymer, polyvinylpyrrolidone (PVP) and other excipient β -cyclodextrin (β-CD) through covalent functionalization for efficient loading and compatible release of sparingly water soluble aromatic anticancer drug SN-38 (7-ethyl-10-hydroxy camptothecin). The drug was loaded onto both GO-PVP and GO-β-CD through the π-π interactions.The release of drug from both the nanocarriers were analyzed in different pH medium of pH 7 (water, neutral medium), pH 5 (acidic buffer) and pH 12 (basic buffer). The loading capacity and the cell killing activity of SN-38 loaded on functionalized GO were investigated comprehensively in human breast cancer cells MCF-7.Our findings shown that the cytotoxicity of SN-38 loaded to the polymer modified GO was comparatively higher than free SN-38. In particular, SN-38 loaded GO-PVP nanocarrier has more cytotoxic effect than GO-β-CD nanocarrier against MCF-7 cells, indicating that SN-38 loaded GO-PVP nanocarrier can be used as promising material for drug delivery and biological applications.

Abstract
Cyclodextrin (β-CD)-functionalized reduced graphene oxide was successfully synthesized by a simple hydrothermal method, followed by conjugating with polyethylene glycol (PEG) and folic acid (FA). Microscopic and spectroscopic techniques were used to characterize the nanocomposites. Photothermal experiments showed that β-CD-functionalized reduced graphene oxide exhibited higher photothermal conversion efficiency in the near infrared region than reduced graphene oxide functionalized with other molecules under the same conditions. Cytotoxicity experiments indicated that rGO@CD@PEG@FA possessed good biocompatibility even at high concentration. When doxorubicin (DOX) was loaded on the rGO@CD@PEG@FA nanocomposite, it showed the stimulative effect of heat, pH response, and sustained drug release. Cytotoxicity experiments also confirmed the targeted effect and high efficiency of the combined therapy. The findings of the present study provide an ideal drug delivery system for malignant cancer therapy due to the advanced synergistic chemo-photothermal targeted therapy and good drug release properties. The rGO@CD@PEG@FA nanocomposite showed the stimulative effect of heat, pH response, and sustained drug release for cancer therapy![]()

[PMID: 27869683 PMCID: PMC5129359 DOI: 10.3390/ijerph13111149] [Citation(s) in RCA: 19] [Impact Index Per Article: 2.4] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 07/01/2016] [Revised: 10/17/2016] [Accepted: 11/07/2016] [Indexed: 12/30/2022]
Abstract
Graphene oxide (GO) is an oxidized derivative of graphene used in biotechnology and medicine. The safety of GO is uncertain, so we evaluated its toxicity in male rats. Rat tail veins were injected with 2.5, 5, or 10 mg/kg GO for seven days and behavioral patterns, pathology, and tissue morphology were assessed. Data show that behaviors were not altered according to an open field test and a functional observational battery test, but histopathological analysis indicated that GO caused inflammation of the lung, liver, and spleen. GO also reduced cholesterol, high density lipoprotein (HDL), and low density lipoprotein (LDL). No other organs were modified. Thus, high concentrations of GO are toxic for the lung, liver, and spleen, but the mechanism by which this occurs requires more study.
