Dear Fellows,

now it is the time to push graphene applications further in terms of easy and low cost production surroundings. Thus I recently dived in the materia and I am facing tons of papers, millions of websites, which makes me quite disorientated and dizzy.

My goal would be to use graphene layers for biosensors, combined with electrochemical impedance spectroscopy. In particular I would like to start by realizing an GO-Layer (Graphene Oxide) on 500x500um large Gold-Elektrode-Pads. I cannot use a CVD-System, but Laser or elechrochemical reduction of the GO should be possible in our Labs. After applieing the GO-Layer I want to find out, what could be the best solution to reduce it to Graphene. I don't think that I need a Mono-Layer right? Is it possible to apply GO with spin- or dipcoating?

Maybe you can provide me some paper, that will help me find a fitting approach? Do you hove some more information, that I cannot see at the moment?

As allready told, I am quite novice with that topic, but it is that interesting for me, that I dont fear some extra effort to get into it.

Thank you in advance for your input.

Johannes
