To calculate microbes in milk or in the operating-room, it is necessary to make them glow like well-known glow-beetles (Lampyridae gen.) do. Now that the secret of glow-beetles’ luminescence has been discovered, and researchers of the Lomonosov Moscow State University not only synthesize the enzyme required for luminescence, but they also produce snap analysis sets based on it, the sets allowing to literally calculate microbes practically in any analysis object within several minutes. The most complicated cases would require the six-hour analysis.
“Our method is based on measuring intensity of luminescence, which occurs upon interaction of a special enzyme, luciferase, with molecules of the so-called ATF - adenosinetriphosphoric acid, says Professor Ugarova, (Doctor of Science (Chemistry)), research manager. This substance called universal accumulator and energy source of living organisms exists in any bioplast. Accordingly, it does exist in microbes as well.”
If membranes of microbe’s sells are destroyed, ATF will, bluntly speaking, simply flow out of them and its quantity may be determined with the help of luciferase. The relation is direct: the more bioplast the sample contains, the more ATF is contained in the solution and the more it will glow upon addition of the enzyme. Certainly, this is a highly simplified outline of the process, and the way from the first investigations up to a simple and reliable methodology took years. However, it has been almost passed through, at any rate the first pilot batches of snap analysis sets have already been released.

When your car knows how you feel

The more electronics steer, accelerate and brake cars, the more important it is to protect them against cyber-attacks. That is why 15 partners from industry and academia will work together over the next three years on new approaches to IT security in self-driving cars. The joint project goes by the name Security For Connected, Autonomous Cars (SecForCARs) and has funding of €7.2 million from the German Federal Ministry of Education and Research. Infineon is leading the project.
Vehicles already offer diverse communication interfaces and more and more automated functions, such as distance and lane-keeping assist systems. At the same...
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...
