Functionalized Graphene Nanocomposites

Antimicrobial Bamboo Materials Functionalized with ZnO and Graphene Oxide Nanocomposites

Bamboo materials with improved antibacterial performance based on ZnO and graphene oxide (GO) were fabricated by vacuum impregnation and hydrothermal strategies. The Zn2+ ions and GO nanosheets were firstly infiltrated into the bamboo structure, followed by dehydration and crystallization upon hydrothermal treatment, leading to the formation of ZnO/GO nanocomposites anchored in the bulk bamboo....

Nanomaterials and Nanotechnology Functional Oxide Nanomaterials and Nanocomposites for the Removal of Heavy Metals and Dyes

Water scarcity and its contamination with toxic metal ions and organic dyes represent a serious worldwide problem in the 21st century. A wide range of conventional approaches have been used to remove these contaminants from waste. Recently, nanotechnology has been given great scope for the fabrication of desirable nanomaterials with large surface-to-volume ratios and unique surface functionalit...

Chitosan-Functionalized Graphene Oxide as a Potential Immunoadjuvant

The application of graphene oxide (GO) as a potential vaccine adjuvant has recently attracted considerable attention. However, appropriate surface functionalization of GO is crucial to improve its biocompatibility and enhance its adjuvant activity. In this study, we developed a simple method to prepare chitosan (CS)-functionalized GO (GO-CS) and further investigated its potential as a nanoadjuv...

LbL: Layer-by-Layer; GOx: Glucose Oxidase; G-chitosan: Reduced Graphene Oxide Nanoplatelets Functionalized with Chitosan; GPSS: Reduced Graphene Oxide Nanoplatelets Functionalized with Poly(Styrenesulfonic Acid)

This work aims the functionalization of reduced graphene oxide nanoplatelets with chitosan (G-chitosan) and also with poly(styrenesulfonic acid) (GPSS), thus forming stable, dispersed aqueous solutions. G-chitosan and GPSS solutions allowed the layer-by-layer (LbL) film formation with glucose oxidase (GOx), establishing multilayered nanostructures with elevated control in thickness and morpholo...
