[Vo]: DNA can detect spin states...

[Mark Iverson]

FYI:
 
"Professor Ron Naaman from the Weizmann Institute in Israel and scientists in 
Germany discovered
that biological molecules in DNA can detect spin states in atoms. The 
researchers fabricated
self-assembling, single layers of DNA attached to a gold substrate. The DNA was 
exposed to electrons
- and the DNA molecules reacted strongly with electrons at one spin, and hardly 
at all with
electrons with a different spin."
