“…Barati et al synthesized a molecular imprinted polymer based on magnetic chitosan/graphene oxide and used it for the selective extraction of fluoxetine from environmental and biological samples prior to its spectrophotometric determination. Due to the multi imprinting sites and high surface area of the magnetic chitosan/GO, high selectivity and adsorption efficiency was observed [96].…”

Graphene oxide (GO) is a chemical compound with a form similar to graphene that consists of one-atom-thick two-dimensional layers of sp2-bonded carbon. Graphene oxide exhibits high hydrophilicity and dispersibility. Thus, it is difficult to be separated from aqueous solutions. Therefore, functionalization with magnetic nanoparticles is performed in order to prepare a magnetic GO nanocomposite that combines the sufficient adsorption capacity of graphene oxide and the convenience of magnetic separation. Moreover, the magnetic material can be further functionalized with different groups to prevent aggregation and extends its potential application. Until today, a plethora of magnetic GO hybrid materials have been synthesized and successfully employed for the magnetic solid-phase extraction of organic compounds from environmental, agricultural, biological, and food samples. The developed GO nanocomposites exhibit satisfactory stability in aqueous solutions, as well as sufficient surface area. Thus, they are considered as an alternative to conventional sorbents by enriching the analytical toolbox for the analysis of trace organic compounds.

Two-dimensional materials (2DMs), especially graphene derivatives, have attracted a wide range of interest in science and technology because of their exceptional physical and chemical properties and large potential application areas in electrochemistry, photonics, bioengineering, electronics and membrane separation fields. Our review focuses on recent advances in the construction of new functional composites using graphene oxide (GO), reduced graphene oxide (rGO) and bio-based macromolecules. The incorporation of bio-based polymers into GO and rGO nanolayers provides a novel way to tailor the properties of 2DMs. Meanwhile, 2DMs/bio-based polymer composites are sustainable and biocompatible. Benefiting from the combination of superior properties of both materials, they are endowed with new functions and new application areas. Here, we compare existing fabrication approaches for 2DMs/bio-based polymer composites. Then, we highlight the properties of composites such as ionic conductivity, molecular transport, mechanical properties, biocompatibility and sustainability. Finally, we discuss recent progress in applications of 2DMs/bio-based polymer composites for efficient ionic and molecular separation technologies, the construction of energy-related devices including fuel cells and transistors, and biomedical engineering.

“…As using GO as the carrier in the synthesis of MIP, the polymerization process will take place near the surface which is conducive to reduce the "embedding" phenomenon of template, and beneficial for the recognition and elution of template. Therefore, comparing to general MIP, the prepared MIP based on GO will show higher adsorption capacity [15][16][17].…”

A novel molecularly imprinted polymer based on graphene oxide was prepared as a solid‐phase extraction adsorbent for the selective adsorption and extraction of cyromazine from seawater samples. The obtained graphene oxide molecularly imprinted polymer and non‐imprinted polymer were nanoparticles and characterized by scanning electron microscopy. The imprinted polymer showed higher adsorption capacity and better selectivity than non‐imprinted polymer, and the maximum adsorption capacity was 14.5 mg/g. The optimal washing and elution solvents for molecularly imprinted solid phase extraction procedure were 2 mL of acetonitrile/water (80:20, v/v) and methanol/acetic acid (70:30, v/v), respectively. The recoveries of cyromazine in the spiked seawater samples were in the range of 90.3–104.1%, and the relative standard deviation was <5% (n = 3) under the optimal procedure and detection conditions. The limit of detection of the proposed method was 0.7 μg/L, and the limit of quantitation was 2.3 μg/L. Moreover, the imprinted polymer could keep high adsorption capacity for cyromazine after being reused six times at least. Finally, the synthesized graphene oxide molecularly imprinted polymer was successfully used as a satisfied sorbent for high selectivity separation and detection of cyromazine from seawater coupled with high‐performance liquid chromatography.
