By means of a microelectrode that measures the impedance and temperature of the tissues, the system enables the state of any organ to be monitored from the moment of its extraction, during its transport, to the moment of the surgical operation to transplant it into a patient.
The Ikerlan-IK4 device, designed in collaboration with the National Centre for Microtechnology (CNM-CSIC) and the Carburos Metálicos company and patented in conjunction with I2M Design S.A., uses a polymer substrate that represents a great advance in biomedical instrumentation, as it does not produce injury in the tissues during transport or surgical manoeuvres. It even opens a new way to control organ rejection, given that the microelectrode can remain implanted for a considerable time without causing injury.
The application has a number of prototypes already and has had clinical trials with organs of animals at Barcelona’s Hospital Clínic. Moreover, it is of particular interest for a process as delicate as an organ transplant, as it provides an objective indicator of the evolution of the organ in which, despite the conservation techniques used – whether with special liquids or in cold -, the duration of the viscera is highly limited (12 hours in the case of the kidney, eight for the liver and only four hours in the case of the heart). The device is used incorporated into a small electronic system which gathers and sends data by telemetry to an external system, enabling the verification of the state of the organ at all times.
Due to medical advances, the transplant of organs is an evermore common medical practice. Thanks to the high number of donors in the Basque Country, this country has one of the highest rates of transplants in the world, with 61 kidney transplants per million inhabitants in 2006; 26.3 liver transplants and 4.7 heart transplants.

A Challenging European Research Project to Develop New Tiny Microscopes
28.03.2017 | Technische Universität Braunschweig
The Institute of Semiconductor Technology and the Institute of Physical and Theoretical Chemistry, both members of the Laboratory for Emerging Nanometrology (LENA), at Technische Universität Braunschweig are partners in a new European research project entitled ChipScope, which aims to develop a completely new and extremely small optical microscope capable of observing the interior of living cells in real time. A consortium of 7 partners from 5 countries will tackle this issue with very ambitious objectives during a four-year research program.
To demonstrate the usefulness of this new scientific tool, at the end of the project the developed chip-sized microscope will be used to observe in real-time...
Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.
The results will be published on March 22 in the journal „Astronomy & Astrophysics“.
Galaxy clusters are the largest gravitationally bound structures in the universe. With a typical extent of about 10 million light years, i.e. 100 times the...
Researchers at the Goethe University Frankfurt, together with partners from the University of Tübingen in Germany and Queen Mary University as well as Francis Crick Institute from London (UK) have developed a novel technology to decipher the secret ubiquitin code.
Ubiquitin is a small protein that can be linked to other cellular proteins, thereby controlling and modulating their functions. The attachment occurs in many...

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.
