Assembly and application advancement of organic‐functionalized graphene‐based materials: A review

Abstract

Owing to the remarkable physicochemical properties such as hydrophobicity, conductivity, elasticity, and light weight, graphene-based materials have emerged as one of the most appealing carbon allotropes in materials science and chemical engineering. Unfortunately, pristine graphene materials lack functional groups for further modification, severely hindering their practical applications. To render graphene materials with special characters for different applications, graphene oxide or reduced graphene oxide has been functionalized with different organic agents and assembled together, via covalent binding and various noncovalent forces such as π-π interaction, electrostatic interaction, and hydrogen bonding. In this review, we briefly discuss the state-ofthe-art synthetic strategies and properties of organic-functionalized graphene-based materials, and then, present the prospective applications of organic-functionalized graphene-based materials in sample preparation.

Functionalized graphene oxide materials for the fluorometric sensing of various analytes: a mini review

“…Therefore, the tunable and intrinsic qualities of GO-based materials attract manifold applications in the discipline of fluorescent chemosensors as an outstanding fluorophore as well as a potential dual nature fluorescence quencher via charge transfer or resonance energy transfer processes. 49,50,[54][55][56][57]…”

Graphene Oxide: Opportunities and Challenges in Biomedicine

“…In the top-down approach, graphite is treated by e ation (mechanical or electrochemical). The bottom-up approach is a developed appr which contains epitaxial growth, chemical vapor deposition, and the dry ice metho graphene material production [6][7][8] (Figure 2). In this review, graphene oxide (GO), reduced graphene oxide (rGO), and functionalized GO (FGO) are noted among the various allotropic forms of carbons due to their significant surface area, strength, light weight, chemical stability, enhanced cell adhesion, proliferation, differentiation, and application in the repair of tissue [4,5].…”

Graphene Oxide (GO)-based Nanosheets With Combined Chemo/photothermal/Photodynamic Therapy to Overcome Gastric Cancer (GC) Paclitaxel Resistance by Reducing Mitochondria-Derived Adenosine-Triphosphate (ATP)

“…Currently, drug delivery systems (DDSs) based on nanotechnology provide an opportunity to improve the antitumor e cacy of PTX [8,9]. Among all materials, graphene oxide (GO) has considerable potential, owing to physically enormous surface area [10], chemically the π-π stacking interactions originating from the aromatic structure, electrostatic interactions between opposite charges of drug molecules and GO derivatives [11], high thermal conductivity, and plasma membrane traversing capacity [12]. However, low dispersion of GO in protein-rich or salted environments like cell medium and serum, could lead to uncontrollable dose-depended toxicity.…”
