Human organs deteriorate rapidly without free-flowing blood. The condition, known as ischemia, can be a problem during surgical operations or the transport of graft organs. MICROTRANS answer is a small silicon needle with multiple sensors, capable of continuously measuring the electrical impedance of tissues.
Heart surgeons carefully monitor a beating heart on an electrocardiograph. But if they need to artificially stop the heart during a procedure, these measurements may be lacking for as long as 30 minutes.
In the MICROCARD project, an earlier project funded under the European Commissions ESPRIT programme, European researchers tested a system that continuously monitors the condition of organs. They came up with a needle-shaped microsensor, carved from a silicon wafer, for inserting directly into an organ. Its chemical sensors assessed parameters such as pH and potassium, but were more accurate in chemical solutions than in living tissues.

New discoveries predict ability to forecast dementia from single molecule

Researchers from the University of Basel have reported a new method that allows the physical state of just a few atoms or molecules within a network to be controlled. It is based on the spontaneous self-organization of molecules into extensive networks with pores about one nanometer in size. In the journal ‘small’, the physicists reported on their investigations, which could be of particular importance for the development of new storage devices.
Around the world, researchers are attempting to shrink data storage devices to achieve as large a storage capacity in as small a space as possible. In almost...
The more objects we make "smart," from watches to entire buildings, the greater the need for these devices to store and retrieve massive amounts of data quickly without consuming too much power.
Millions of new memory cells could be part of a computer chip and provide that speed and energy savings, thanks to the discovery of a previously unobserved...
What if, instead of turning up the thermostat, you could warm up with high-tech, flexible patches sewn into your clothes - while significantly reducing your...
A widely used diabetes medication combined with an antihypertensive drug specifically inhibits tumor growth – this was discovered by researchers from the University of Basel’s Biozentrum two years ago. In a follow-up study, recently published in “Cell Reports”, the scientists report that this drug cocktail induces cancer cell death by switching off their energy supply.
The widely used anti-diabetes drug metformin not only reduces blood sugar but also has an anti-cancer effect. However, the metformin dose commonly used in the...
A research team from the University of Zurich has developed a new drone that can retract its propeller arms in flight and make itself small to fit through narrow gaps and holes. This is particularly useful when searching for victims of natural disasters.
Inspecting a damaged building after an earthquake or during a fire is exactly the kind of job that human rescuers would like drones to do for them. A flying...
