... a highly precise way of identifying trace quantities of any kind of molecule has been developed by Professor Chad Mirkin, director of Northwestern's Institute for Nanotechnology in Evanston, Illinois, and colleagues.
They work in ``bio-nanotechnology'', in which they have combined two seemingly incompatible materials - proteins, DNA and other building blocks of life plus synthetic structures made of gold.
"We are the first to demonstrate technology that can compete with - and in some cases beat - PCR in many categories," said Mirkin.
