What is rGO?

Reduced graphene oxide (RGO) is the form of GO that is processed by chemical, thermal and other methods in order to reduce the oxygen content, while graphite oxide is a material produced by oxidation of graphite which leads to increased interlayer spacing and functionalization of the basal planes of graphite.

How GO is reduced to rGO?

The graphene oxide (GO) was converted to reduced graphene oxide (rGO) by chemical reduction using ascorbic acid as the reducing agent. The GO and rGO were characterized by UV-visible spectroscopy, FTIR spectroscopy, and X-ray diffraction patterns.

How is rGO made?

In the past, scientists have created rGO from GO by: Treating GO with hydrazine hydrate and maintaining the solution at 100 for 24 hours. Exposing GO to hydrogen plasma for a few seconds. Exposing GO to another form of strong pulse light, such as those produced by xenon flashtubes.

What is graphene oxide used for?

Graphene oxide (GO), an oxidized derivative of graphene, is currently used in biotechnology and medicine for cancer treatment, drug delivery, and cellular imaging. Also, GO is characterized by various physicochemical properties, including nanoscale size, high surface area, and electrical charge.

What is graphene oxide side effects?

Even though graphene oxide is made with the same atoms as our organs, tissues and cells, its bi-dimensional nature causes unique interactions with blood proteins and biological membranes and can lead to severe effects like thrombogenicity and immune cell activation.

Is RGO a 2D material?

Graphene oxide and rGO are 2D compounds with the same structure as graphene with some hydroxyl, carboxyl and ether functional groups on their sheets.

What are the side effects of graphene oxide?

What does graphene oxide do to the brain?

“Graphene oxide interacts with the part of the brain responsible for the formation of fear-related memories, which cause anxiety.

What is the problem with graphene?

“The problem is that, when you exfoliate graphene mechanically through force or by taking a chemical-based approach, you can introduce defects into the structure of the material,” says Koziol. “With the CVD technique, harmful acids might be used to dissolve the substrate and separate it from the graphene.
