The average persons heart pumps about a gallon of blood per minute, a rate that can easily triple or quadruple during exercise.
The rapid flow of blood through the body is a major roadblock to the use of gene therapy to cure diseases. When injected into the blood, vector viruses – which carry corrective genes – tend to shoot past the target organ or tissue rather than sticking to it, like grains of sand moving past stones in a fast-flowing river.
Now, University of Florida gene therapy and biomedical engineering researchers have demonstrated a novel approach to the problem. In a July article in Molecular Therapy, they report attaching the adeno-associated virus, a widely used gene carrier, to the surface of tiny manufactured balls known as microspheres, each containing a miniscule particle of iron oxide. Using a magnet placed under culture dishes, the researchers were able to coax large amounts of the microspheres to target areas of the cultures. In related experiments in mice, the researchers showed the microspheres clung to cells or organs longer than the virus alone did.

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...
