Stem cells help researchers study the effects of pollution on human health

12-Aug-2015 - A recent study shows that embryonic stem cells could serve as a model to evaluate the physiological effects of environmental pollutants efficiently and cost-effectively. The use of stem cells has found another facade. In the world we live in today, people are constantly exposed to artificial ...

Materials: The first graphene-based chiral sensor

03-Aug-2011 - 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 ...

New X-ray technique distinguishes between that which previously looked the same

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

27-Jul-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 ...

Photoelectric switch

08-Apr-2009 - 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 from ...

Single molecules cooling off

Surface-enhanced Raman scattering has been used to probe single molecular behaviour by scientists in China and Sweden

28-Jan-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 molecules, ...
