Steve Clark writes of a new DNA nanotechnology diagnostic method: "Bio-bar-Code Amplification (BCA) is a new diagnostic method that now rivals PCR. BCA can also scan a sample for many different disease targets simultaneously. This new technology, based on gold nanoparticles and DNA, is easier to use, faster, more accurate, and less expensive, making it a leading candidate in point-of-care diagnostics. The Northwestern University team demonstrated it can detect as few as 10 DNA molecules in a matter of minutes, and believes it can be commercially available for certain diseases in one year. Additional info can be found on the Press Release."
