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.

3D images of cancer cells in the body: Medical physicists from Halle present new method
16.05.2018 | Martin-Luther-Universität Halle-Wittenberg
A research team led by physicists at the Technical University of Munich (TUM) has developed molecular nanoswitches that can be toggled between two structurally different states using an applied voltage. They can serve as the basis for a pioneering class of devices that could replace silicon-based components with organic molecules.
The development of new electronic technologies drives the incessant reduction of functional component sizes. In the context of an international collaborative...
At the LASYS 2018, from June 5th to 7th, the Laser Zentrum Hannover e.V. (LZH) will be showcasing processes for the laser material processing of tomorrow in hall 4 at stand 4E75. With blown bomb shells the LZH will present first results of a research project on civil security.
At this year's LASYS, the LZH will exhibit light-based processes such as cutting, welding, ablation and structuring as well as additive manufacturing for...
There are videos on the internet that can make one marvel at technology. For example, a smartphone is casually bent around the arm or a thin-film display is rolled in all directions and with almost every diameter. From the user's point of view, this looks fantastic. From a professional point of view, however, the question arises: Is that already possible?
At Display Week 2018, scientists from the Fraunhofer Institute for Applied Polymer Research IAP will be demonstrating today’s technological possibilities and...
