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.

Max Planck researchers revel the nano-structure of molecular trains and the reason for smooth transport in cellular antennas.
Moving around, sensing the extracellular environment, and signaling to other cells are important for a cell to function properly. Responsible for those tasks...
Researchers at the University of New Hampshire have captured a difficult-to-view singular event involving "magnetic reconnection"--the process by which sparse particles and energy around Earth collide producing a quick but mighty explosion--in the Earth's magnetotail, the magnetic environment that trails behind the planet.
Magnetic reconnection has remained a bit of a mystery to scientists. They know it exists and have documented the effects that the energy explosions can...
Biochips have been developed at TU Wien (Vienna), on which tissue can be produced and examined. This allows supplying the tissue with different substances in a very controlled way.
Cultivating human cells in the Petri dish is not a big challenge today. Producing artificial tissue, however, permeated by fine blood vessels, is a much more...
Faster and secure data communication: This is the goal of a new joint project involving physicists from the University of Würzburg. The German Federal Ministry of Education and Research funds the project with 14.8 million euro.
In our digital world data security and secure communication are becoming more and more important. Quantum communication is a promising approach to achieve...
