I would like to know what other materials pierce cells - I am sure there are many - also, what happens to the material when absorbed by the cell - is it incapsulated and broken down, or neutralized?  The image looks bad (great image btw), but what are the long term affects?

Is graphene a naturally occuring substance or man made??

This does not sound positive for the future of graphene. Thanks for the information. Even though there are some positiveness brought into this article by the information provided in the para "...developing safer methods of manufacturing, handling, and utilizing them throughout their lifecycles". But I think that the world is moving to the future, when electronics might be part of every activities in our lives, there will be stricter norms for a safer environment, better heath, better quality of life...like Europe making regulatory compliance requirement for all electronics RoHS compliant by 2017...regulatory compulsions might impose stricter norms going forward and could be a hurdle for Graphene if this study is proven and approved by others. What do you think?

Carbon nanotubes had similar threats reported as well. The exotic properties of 2D sheets of carbon atoms may have benefits but the possible adverse effects also need to studied.

A graphene ban?

Sounds like a no-brainer that the toxicity of graphene would preclude its use in in-body medical devices, but then again the article implies that the study is concerned about the safe manufacturing process. I wonder if the medical regulations will ban graphene for certain uses.

David Patterson, known for his pioneering research that led to RAID, clusters and more, is part of a team at UC Berkeley that recently made its RISC-V processor architecture an open source hardware offering. We talk with Patterson and one of his colleagues behind the effort about the opportunities they see, what new kinds of designs they hope to enable and what it means for today’s commercial processor giants such as Intel, ARM and Imagination Technologies.
