RE: Graphene Oxide ....
La Quinta Columna has shared on their official Telegram account more exclusive photos of graphene oxide in AstraZeneca's vaccination vial.

Yesterday they had anticipated one in the Chilean program Dirección Correcta.

These photos were taken by another Spanish researcher whose has not yet been revealed.

4.4.1 GO as an unconventional soft material
GO is an intriguing material. As a functionalized single atomic layer of carbon, the thickness of GO is approximately 1 nm. On the other hand, the lateral length of GO sheets can span to micrometres (Figure 14.1(b)). Thus, GO straddles across the two abruptly different length scales typical of molecules and particulate materials. This molecule–particle duality makes GO an interesting material to study from the perspectives of both chemistry and materials science. Furthermore, the length scales associated with GO coincide with the length scales associated with soft materials, such as polymers, colloids, amphiphiles and liquid crystals, which are held together by weak interactions comparable to thermal fluctuation [27]. The softness of GO is also apparent from a structural mechanics point of view – many materials, even hard and brittle ones, can become soft and flexible when their aspect ratio increases. Most notably, the chemical structure of GO predicts that GO should exhibit many soft material properties.

RE: Graphene Oxide ....
Graphene oxide (GO) and reduced graphene oxide (rGO) were demonstrated in the past decade as biocompatible carbon-based materials that could be efficiently used in bioelectrochemical systems (BESs). Specifically, for redox enzyme encapsulation in order to improve electron communication between enzymes and electrodes. The addition of GO to different solvents was shown to cause gelation while still allowing small molecule diffusion through its gel-like matrix. Taking the combination of these traits together, we decided to use GO hydrogels for the encapsulation of enzymes displayed on the surface of yeast in anodes of microbial fuel cells. During our studies we have followed the changes in the physical characteristics of GO upon encapsulation of yeast cells displaying glucose oxidase in the presence of glucose and noted that GO is being rapidly reduced to rGO as a function of glucose concentrations. GO reduction under these conditions served as a proof of electron communication between the surface-displayed enzymes and GO. Hence, we set out to study this phenomenon by the encapsulation of a purified glucose dehydrogenase (in the absence of microbial cells) in rGO where improved electron transfer to the electrode could be observed in the presence of phenothiazone. In this chapter, we describe how these systems were technically constructed and characterized and how a very affordable matrix such as GO could be used to electrically wire enzymes as a good replacement for expensive mediator containing redox active polymers commonly used in BESs.
