$2 egg-beater could save lives in developing countries

15.10.2008
Plastic tubing taped to a handheld egg-beater could save lives in developing countries, the Royal Society of Chemistry's journal Lab on a Chip reports.

The low-cost centrifuge replacement can separate plasma from blood in minutes, which is used in tests to detect lethal infectious diseases responsible for half of all deaths in developing countries.

George Whitesides and colleagues at Harvard University, US, say the plasma obtained is easily good enough to use in tests to detect diseases such as Hepatitis B and cysticercosis.

"The object was to separate serum [plasma] from blood using readily-obtained materials in a resource-constrained environment," explains Whitesides.

The equipment can be bought from shops for around two dollars. It needs no special training to use, no electricity or maintenance, and can be sterilised with boiling water and reused.

The user can even prepare several samples at once - just by taping more lengths of tubing to the beater.

Contrast this with the bulky, sensitive commercial centrifuges, costing thousands of dollars and requiring extensive operation training, and it's easy to see how this development could save lives.

"This technique is simple and works remarkably well," says Doug Weibel, an expert in microbiology at the University of Wisconsin-Madison, US. "This technique complements several other 'simple solutions' that the Whitesides group has developed to tackle point-of-care diagnostics in resource-poor settings."

Im Focus: Giant Magnetic Fields in the Universe

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...

Im Focus: Tracing down linear ubiquitination

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...

Im Focus: Polymer-coated silicon nanosheets as alternative to graphene: A perfect team for nanoelectronics

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.

Im Focus: Researchers Imitate Molecular Crowding in Cells

Enzymes behave differently in a test tube compared with the molecular scrum of a living cell. Chemists from the University of Basel have now been able to simulate these confined natural conditions in artificial vesicles for the first time. As reported in the academic journal Small, the results are offering better insight into the development of nanoreactors and artificial organelles.
