The particular substrate is not important, yet. The underlying technology<br>
is much more interesting. The choice of substrate happens for many, more<br></blockquote><div><br>Natasha asked about chemistry, conversation ensued and we got to biology. The substrate was my point about OLED, not that it was important - only that it is available right now. <br>

we know and can control (life) in the bootstrap. Proteins and DNA are<br>
great for self-assembly, as long as you can't do your own self-assembly<br>
from scratch, or use machine-phase which allows you to maximize functionality<br>
concentration/volume down to the theoretical limit. This means we'll<br>
lose biological components along the way, first as sacrificial<br>
scaffolding, and then completely. No harsh feelings, really.<br>
<br>
So in general don't latch onto the organic/inorganic thing.<br></blockquote><div><br>Again, DNA is available and being used right now (albeit primitively). Machine-phase nano-magic is still only being talked about... Unless y'all have been withholding links to interesting science?<br>

The distinction is artificial in practice, and if we're, say, using<br>
graphene/diamond spintronics as a optimal substrate it isn't for<br>
some magic reasons. It's just carbon is special in that it makes nicely<br>
stable chains and cages which no other element can as well. From<br>
that property stem other remarkable thermal and electronic properties.<br>
Of course it won't be pure carbon, whether it's nitrogen vacances,<br>
SiC islets or transition metal groups in active machine-phase<br>
or synthetic enzyme centers.<br></blockquote></div><br>Oh.. well then.. I guess... uh... I'll just take a nap until all they get it all worked out. :)<br>
