New analytical tool helps detect cancer
...g these materials is that they must be arranged in architectures
that promote electron transport and prevent energy wasting recombination. The complexes must also be interfaced with a conducting material in order to harvest the energy. The controlled growth offered by DMEG can help overcome these hurdles. Another ...

are determined and controlled by crosslinking proteins, which have two sticky ends that bind to different filaments. In order to understand the underlying forces and to optimise the mechanical properties of these architectures, one must study biomime...
