Small Sensor Sparks Big Interest
"I have no doubt that eventually we will see artificial molecular devices which will possess some or all of the characteristics of life, such as self-assembly, self replication, self-repair and, possibly and most importantly, the capability to evolve. "The single-molecule feature ... represents in principle the ultimate in sensitivity -- you can't do better than detecting a single molecule," said team leader Giovanni Zocchi, assistant professor of physics.
