Scientists have made a polymer gel that is able to contract through the action of artificial molecular motors. When activated by light, these nanoscale motors twist the polymer chains in the gel, which as a result contracts by several centimeters.
The new technique is a non-invasive procedure to detect the severity of an allergic reaction to amoxicillin. The developed biosensor platform is based on gold nanodisks, is very sensitive and works label-free, detecting the changes in the refraction index occurring at its surface after the binding of IgEs specific for amoxicillin.
A new semiconductor laser developed at Yale has the potential to significantly improve the imaging quality of the next generation of high-tech microscopes, laser projectors, photolithography, holography, and biomedical imaging.
The Phantoms Foundation and ICEX Spain Trade and Investment, in cooperation with the Embassy of Spain (Economic and Commercial Office) in Tokyo bring together, for the eighth time, a nanoscience and nanotechnology Pavilion at nano tech 2015 (Spanish Pavilion - East Hall 6/Booth 6P-23).
Artificial implants such as pacemakers often cause complications because the body identifies them as foreign objects. Researchers have now demonstrated a simple method to fabricate cellulose-sheaths for implants, whose micro-structured surface makes them especially biocompatible.
A new composite material which prevents metal corrosion in an environmentally friendly way, even under extreme conditions is presented. It can be used wherever metals are exposed to severe weather conditions, aggressive gases, media containing salt, heavy wear or high pressures.
