Biosensing With A DNA-Diamond-Silicon Sandwich

Posted by michael on Wednesday March 5, 2003 @05:05AM from the anything-for-homeland-security dept.

Makarand writes "A unique diamond film with DNA attached to it coupled with sensitive microelectronics might be the sensor needed to sniff out harmful biological agents. If DNA is attached to diamond it is possible to electronically detect the electrical response when biomolecules bind to the DNA-diamond surface. A DNA-Diamond interface deposited on a silicon surface can act as a sensitive biosensor. These inexpensive and compact sensors can make it possible to continuously scan public places like airports and subways and send out security alerts to agencies if required."

I have no idea, but I think artifical diamonds might work for this kind of purpose, sicne brilliance and clarity and whatnot may not be as important.

Just conjecture, I may be totally wrong.
