Monitoring critical blood levels in real time in the ICU

23.10.2015

EPFL has developed a miniaturized microfluidic device that will allow medical staff to monitor in real time levels of glucose, lactate a.s.o. and react more quickly

No larger than a pack of chewing gum, the prototype developed by EPFL's Integrated Systems Laboratory (LSI) is deceptively simple in appearance. But this little black case with two thin tubes sticking out contains some real miniaturized high-tech wonders.

"We embedded biosensors in it to measure several different substances in the blood or blood serum along with an array of electronics to transmit the results in real time to a tablet via Bluetooth," said Sandro Carrara, an LSI scientist.

Capable of being connected to a drainage tube that's already in place, the new system is much less invasive than the many monitoring devices that it's designed to replace.

It keeps constant tabs on the blood levels of five substances: metabolites (glucose, lactate and bilirubin) and ions (calcium and potassium), all of which indicate changes in the condition of intensive-care patients.

"Nowadays, several of these levels are measured periodically. But in some cases, any change in level calls for an immediate response, something that is not possible with the existing systems," said Dr. Carrara.

Building on this principle, up to 40 molecules could be monitored in real time. This advance will drastically reduce the number of machines cluttered around patients - an obvious practical advantage for the medical staff, not to mention the psychological boon for loved ones.

The prototype, which was made with a 3D printer, has been successfully tested on rodents. Discussions are now under way for tests to be carried out at the University Hospital of Lausanne (CHUV). And a number of manufacturers have already expressed serious interest in developing this device. "We could hit the market in two to three years," said Dr. Carrara.

This progress towards more precise and effective medicine was achieved under the Nano-Tera initiative, which is financed by the Swiss government. The device was unveiled on October 22nd in Atlanta at the 2015 BioCAS Conference.

Im Focus: Novel silicon etching technique crafts 3-D gradient refractive index micro-optics

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.

Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...

Im Focus: Quantum Particles Form Droplets

In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.

“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...

Im Focus: MADMAX: Max Planck Institute for Physics takes up axion research

The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.

The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...

Im Focus: Fraunhofer ISE Develops Highly Compact, High Frequency DC/DC Converter for Aviation

The efficiency of power electronic systems is not solely dependent on electrical efficiency but also on weight, for example, in mobile systems. When the weight of relevant components and devices in airplanes, for instance, is reduced, fuel savings can be achieved and correspondingly greenhouse gas emissions decreased. New materials and components based on gallium nitride (GaN) can help to reduce weight and increase the efficiency. With these new materials, power electronic switches can be operated at higher switching frequency, resulting in higher power density and lower material costs.

Researchers at the Fraunhofer Institute for Solar Energy Systems ISE together with partners have investigated how these materials can be used to make power...
