Full Description:

Using light to imprint features onto polymer or plastic, Associate Professor Nick Fang's research led his team to disprove the established diffraction limit, proving for the first time that it is possible to print sub-wavelength features one-hundredth the thickness of a human hair. His discovery allows manufacturers to imprint finer features into items such as DVDs to significantly improve storage capabilities, or to probe the traffic of protein or DNA.
