Gust MEES's insight:
L'un des problèmes réduisant l'efficacité de la photothermie dans la lutte contre les tumeurs est la défense de ces dernières, qui produisent des «protéines du stress» pour se protéger contre la chaleur.

La bioélectronique du futur pourrait bien reposer sur l’utilisation de transistors à effet de champ fabriqués avec du graphène.
Gust MEES's insight:
Les biophysiciens se proposent maintenant de réaliser des blocs de 1.000 SGFET au graphène, ce qui permettrait la réalisation d’implants rétiniens. Il ne devrait pas y avoir d’obstacle technologique à la réalisation de tels systèmes, mais il leur reste à montrer qu’en plus de permettre la survie des neurones, ils n’endommagent pas les tissus nerveux.

Most flexible polymers are inherently flimsy. When you look at their micro-structures it's easy to see why: They look like piles of entangled spaghetti strands.

A technology that would enable low-cost, high efficiency solar cells to be made from virtually any semiconductor material has been developed by researchers with the U.S. Department of Energy (DOE)'s Lawrence Berkeley National Laboratory (Berkeley Lab) and the University of California (UC) Berkeley.
This technology opens the door to the use of plentiful, relatively inexpensive semiconductors, such as the promising metal oxides, sulfides and phosphides, that have been considered unsuitable for solar cells because it is so difficult to taylor their properties by chemical means.

Chemists develop a nanopaste to repair bone defects
Gust MEES's curator insight,
February 20, 2013 9:43 AM
The UDE researchers expect that the paste will have a long-lasting effect since the nanoparticles are released successively and thus continuously stimulate the surrounding cells. They have demonstrated that the paste works in three different cell types. Further tests now have to be conducted. Epple and his co-researchers hope that “our development will be used several years from now in the field of traumatology and in the treatment of osteoporosis.”
