A reusable, natural and cheap amylose-functionalised graphene sensor was developed for highly sensitive and visual fluorescent chiral sensing by a team in China.The team found that the sensor’s detection sensitivity toward L-tryptophan was over 100 times higher than that of recently reported ...
A new method forms the basis for the widespread use of an X-ray technique which distinguishing types of tissue that normally appear the same in conventional X-ray images
07-27-2010
Traditional X-ray images can clearly distinguish between bones and soft tissue, with muscles, cartilage, tendons and soft-tissue tumours all look virtually identical. The phase-contrast technique developed a few years ago at the Paul Scherrer Institute enables X-ray images to be produced that ...

A collaboration of scientists from various Beijing institutes, have made a pH-switchable, DNA-quantum dot hybrid that can also generate a photocurrent depending on the pH, allowing DNA to change conformation from a quadruplex to a double strand. Zhiyong Tang, Dongsheng Liu and colleagues ...
Surface-enhanced Raman scattering has been used to probe single molecular behaviour by scientists in China and Sweden
01-28-2009
Probing single molecular behaviour using surface-enhanced Raman scattering (SM-SERS) has attracted considerable attention recently, although there are a few drawbacks. One major problem is the strong spectral-fluctuation (also known as ‘signal-blinking’) that is associated with single ...
