Is this how Cyborgs, and then ‘Borgs, began?

And what, pray tell, is graphene?

FReepmail me if you want on or off my health and science ping list.
As I read this I thought about human cell toxicity. If that can be managed or is very slight then this would be a great breakthrough. Cost is an issue.
Graphene is graphite - which is actually composed of single-atom-thick planes of carbon atoms in a planar lattice arrangement. An individual plane of graphite, called graphene, can be separated from a piece of graphite by simply putting Scotch tape on graphite and then pulling the tape off. The gray that can be seen sticking to the transparent tape will be one, or a few, layers of graphene. Graphene has interesting properties and is thought to be a candidate for microelectronic application. You should definitely do a search on the term and learn more.

The toxic mechanism is purely mechanical, it slices through the cell wall (membrane) and extracts phospholipids killing the cell. The effect is the same with human cells, but we have so many that the graphene ends up surrounded with serum and unable to touch more cells.
It's not something you would want to ingest or inject. Surface use on wounds and non-living surface sterilization appear to be the best use.
I had a girl friend once who yanked out my phospholipids; it can be exceedingly painful.
Agreed and I saw that, too. I was thinking of more serious trauma or battlefield injuries and the risk of introducing it into the bloodstream v. preventing bacterial infection.
So from now on I can just rub a pencil on it?
bttt
I've heard that Eaker threatens to do that to folks who cross him.
You win one internet for the best answer to a question.
You provided sufficient information to answer the question.
You provided accurate information.
You provided readily understandable information.
You encouraged further study.
Are you perchance a teacher?
Typically only on Thursdays.
You encouraged further study . . . You win one internet for the best answer to a question.
Thanks. In my mind neverdems simple link to Wikipedia (see #8) was very possibly more excellent.Are you perchance a teacher?
Although both my parents taught, one as a lifetime career and the other not, and three of my grandparents were teachers, my brother and I were both engineers. Tho my brother has done volunteer tutoring for a coworker taking college courses and for a child who wasnt getting what the math book - he said there the book was so pathetic that there wasnt actually any actual math in it - should have been teaching. I confess that this isnt actually the first time someone has asked me the question, tho. and if you saw the FReepmail note I dropped to AnalogReigns about his screen name, I suppose that you would really think I was a pedant - if not pedantic.
Engineer was my second guess...
