A series of experiments reported on this week in the journal Science shows for the first time that novel biosensor dyes can directly reveal activation of proteins in individual living cells.
The research, led by Dr. Klaus M. Hahn, professor of pharmacology at the University of North Carolina at Chapel Hills School of Medicine, demonstrated that at least one of the dyes Hahn developed makes it possible to dramatically visualize the changing activation and intracellular location of the protein Cdc42.
The novel dyes open new possibilities for screening the molecular effects of drugs within the living cell. Currently, automated "high throughput" drug assays are conducted on thousands of cells at a time, but in vitro, in laboratory test tubes. Cdc42, a member of the Rho family of proteins, regulates multiple and sometimes opposite functions within the cell: movement, proliferation, cell death and shape.

A research team led by physicists at the Technical University of Munich (TUM) has developed molecular nanoswitches that can be toggled between two structurally different states using an applied voltage. They can serve as the basis for a pioneering class of devices that could replace silicon-based components with organic molecules.
The development of new electronic technologies drives the incessant reduction of functional component sizes. In the context of an international collaborative...
At the LASYS 2018, from June 5th to 7th, the Laser Zentrum Hannover e.V. (LZH) will be showcasing processes for the laser material processing of tomorrow in hall 4 at stand 4E75. With blown bomb shells the LZH will present first results of a research project on civil security.
At this year's LASYS, the LZH will exhibit light-based processes such as cutting, welding, ablation and structuring as well as additive manufacturing for...
There are videos on the internet that can make one marvel at technology. For example, a smartphone is casually bent around the arm or a thin-film display is rolled in all directions and with almost every diameter. From the user's point of view, this looks fantastic. From a professional point of view, however, the question arises: Is that already possible?
At Display Week 2018, scientists from the Fraunhofer Institute for Applied Polymer Research IAP will be demonstrating today’s technological possibilities and...
