This week, at the 243rd National Meeting & Exposition of the American Chemical Society (ACS) in San Diego, Dr David H Gracias, from Johns Hopkins University in Baltimore, Maryland, gave an account of the progress he and his team are making in this area. <\/p>\n
Gracias told the press: <\/p>\n
\"Cargo-carrying bacteria may be an answer to a major roadblock in using nano-medicine to prevent, diagnose and treat disease.\" <\/p>\n
Nano-technology concerns itself with making ultra-tiny devices, small enough to fit a million or so on the head of a pin. In medicine the idea is to use them to transport particles of medication, sensors and other materials to precise locations in the human body. <\/p>\n
But it is not easy to devise self-sustaining motors and propulsion mechanisms at this scale: so scientists are increasingly turning to nature, where organisms like bacteria are already of the right scale and capable of moving on their own. <\/p>\n
As Gracias explained: <\/p>\n
\"Currently, it is hard to engineer microparticles or nanoparticles capable of self-propelled motion in well-defined trajectories under biologically relevant conditions.\" <\/p>\n<\/p>\n
