Biosensing With A DNA-Diamond-Silicon Sandwich

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."

    Now let me see this technology put to use to make MY life better. I this syetm in place in my apartment so that whever a foul odor is present (Ie my gargantuan roommate take the Browns to the Suberbowl) this DNA diamond detects it and sends a text message to my cell phone. "DO NOT COME HOME FOR 4 HOURS."

    This is the kind of stuff they said would happen in the future!
