Anyone who has given blood or received a transfusion knows just how vital blood supplies are. Although no one would doubt the need for blood in life-saving emergencies, there are growing concerns about its use in routine operations.
There are other limitations as Professor Chris Cooper explained: ‘Blood has a short shelf-life, needs to be matched for blood group and there is the ever-present possibility of a new blood-borne virus, such as HIV-AIDS, contaminating the supply.’
It is these concerns that have for some time fuelled the drive, amongst academic and industrial communities, to develop an artificial replacement that would be guaranteed virus free and storable, for long periods of time, in ambulances and locations far from hospitals.
Professor Cooper, with his colleagues Professor Mike Wilson and Dr Brandon Reeder, have now received £114,938 from the Biotechnology and Biological Sciences Research Council to develop their patented ideas for a novel blood substitute.
Professor Cooper said: ‘Our inventions relate to toxic molecules called free radicals that are produced from haemoglobin, the red oxygen carrying protein in blood. We have worked out a way to control radical reactivity when modified haemoglobins are used as artificial oxygen carriers.’
The new molecules are being manufactured by collaborators at the University of Lund, Sweden, and tested in the Federal Drug Administration laboratories in the US under the supervision of Essex graduate Dr Abdu Alayash.

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.
