Nanobots get to the heart of the matter

Here’s a Valentine’s Day special for all my reader out there (missing “s” intended, sometimes I think I’ve got one reader out there).

At any rate,  a new breed of nanobots is being designed to assist doctors by going where no surgeon or technology has gone before — the human heart.

Engineers and scientist working on the development of these nanobots — the size of only a few molecules — believe they could reach liquid parts of the body difficult or impossible to get to using today’s medical practices, precisely delivering drugs to areas such as the eyeball cavity or arteries in the heart.
