This chapter focuses on the functionalization of graphene, mainly in graphene oxide (GO) and reduced graphene oxide (rGO). In this sense the main syntheses for obtaining GO and rGO, as well as their characterizations and ...

For the first time a critical analysis of the influence that four different graphene oxide reduction methods have on the electrochemical properties of the resulting reduced graphene oxides (RGOs) is reported. Starting from ...

Graphene is a material that has attracted attention with regard to sensing and biosensing applications in recent years. Here,we report a novel treatment (using ultrasonic bath and ultrasonic tip) to obtain graphene oxide ...

This work presents the development of a sensor based on reduced graphene oxide (rGO) modified with silver nanoparticles (AgNPs) for the oxidation of estriol hormone. The morphology and electrochemical behavior of the ...

A simple, low cost, and green method of hydrothermal synthesis, based on the addition of l-ascorbic acid (L-AA) as a reducing agent, is presented in order to obtain reduced graphene oxide (rGO) and hybrid rGO-MoO2 aerogels ...

The present work reports the development of an electrochemical sensor based on molecularly imprinted polymer for the determination of D-xylose. This is the first report of its kind in the literature. The sensor was prepared ...

Carbofuran (CBF) is a pesticide currently prohibited in many countries. It can cause serious damages in the nervous system and has been associated with cancer. However, CBF residues are still found in food samples around ...

A novel electrochemical sensor based on a glassy carbon electrode, modified with reduced graphene oxide and copper nanoparticles (GC/rGO-CuNPs), was developed for the determination of glyphosate herbicide (GLY) by differential ...
