Nanoswitches converting light into macroscopic motion

Researchers of the University of Twente's MESA+ research institute have developed spiral ribbons made of molecules, that are able to convert light into complex macroscopic motion. Therefore, they managed to amplify molecular motion and translate it to the macroscopic world.

Researchers hijack cancer migration mechanism to 'move' brain tumors

One factor that makes glioblastoma cancers so difficult to treat is that malignant cells from the tumors spread throughout the brain by following nerve fibers and blood vessels to invade new locations. Now, researchers have learned to hijack this migratory mechanism, turning it against the cancer by using a film of nanofibers thinner than human hair to lure tumor cells away.

Superabsorbing fullerenes

Fullerene bisadducts are promising electron-accepting materials because of the increased open-circuit voltage of BHJSCs based on these compounds compared with those based on PCBM. That led researchers to synthetize C60 bisadducts connected with the strong absorber perylenediimide (PDI) in a cyclic fashion.

The ultimate miniaturization of lamps: a single-molecule LED

The ultimate challenge in the race to miniaturize light emitting diodes (LED) has now been met: researchers have developed the first ever single-molecule LED. The device is formed from a single polythiophene wire placed between the tip of a scanning tunneling microscope and a gold surface. It emits light only when the current passes in a certain direction.
