No!No!No! Competition keeps prices lower! :-)

Graphene is not even established yet and it is already being replaced?! The risks of research have gotten much higher!

I can hear the silicon based aliens on zeta reticuli prime rolling their eyes at their colleagues suggestion of the possibility of carbon based life forms.

I think the silicon based life forms on star trek were on a planet with a high temperature. Makes sense...

Next big thing will be germanene.

It requires very high temperature for silicon-base bio-chemistry to occur. It is not a surprise you do not find it on earth.

Incorporating silicon is one thing. It's not unlike incorporating calcium for use in bones, or iron for use in blood. Life requires a great deal of chemical diversity and silicon just isn't chemically capable of that kind of diversity under any known conditions (temperature and pressure). Fats, Carbohydrates, Nucleic Acids, and Proteins are all carbon based and represent an enormous diversity of chemical structures. You just can't come close to that with silicon based molecules. I'm not aware of silicon being used in an "organic" fashion. I'd love to see examples, though.

if claim verified then it is really something exciting. Natural 2D silicon can be something that can found useful device application without complicated processing.

And I read somewhere that the needles/spines/hairs on a nettle are actually silica so there is an example of silicon being an important part of the plant.

I seem to remember learning that some living organisms on earth incorporate silicon in an organic manner. As I remember it was mainly single-celled organisms, some plankton and some mosses. I am going back 40 years but I seem to remember that some friend-of-a-friend was going to do a PhD studying Canadian moss that includes silicon-based organic chemistry. Perhaps he never found the moss and never got his PhD.
