Structure of hepatitis B virus mapped

28.07.2008
Utrecht University researchers develop method to spray virus

Using a newly developed method, Utrecht University researchers have mapped the structure and composition of the hepatitis B virus. The researchers were able to map the structure by spraying the virus.

Their research brings us a step closer to understanding and combating hepatitis B infection. The method can also be used to analyse other viruses. The results of the search were recently published in two renowned scientific journals: Proceedings of the National Academy of Sciences USA and Angewandte Chemie International Edition England.

To better understand and deal with viral infections, it is essential to examine the virus carefully at molecular level. However, the virus is too large to do this using the standard methods. For that reason, especially for this project, Utrecht University researcher Charlotte Uetrecht developed a modified mass spectrometer that can spray the virus intact. She did this together with Prof. Albert Heck (Utrecht University) and researchers from America and Amsterdam.

Preventing viral infection

Using the modified mass spectrometer, the researchers looked at the structure and composition of the hepatitis B virus, a virus that causes severe liver ailments in humans. With the spectrometer, the researchers not only observed various forms of the virus, but they also saw the virus’ molecular structure. This makes it possible in the future to block the production of viruses, and in that way to combat viral infection. The technology developed can also be used to map and identify other viruses, such as viruses that can potentially be used in weaponised form by terrorists.

Sneezing

Mass spectrometry is a technology with which scientists can identify molecules. Among other things, this technology is used in dope testing and for identifying paint traces in forensic investigations. Mass spectrometry works particularly well with smaller molecules. Viruses however are a million times greater in mass. To be able to use mass spectrometry nevertheless, researchers spray the virus with water through a high-tension electric charge. This technique separates the viruses from the water, enabling researchers to examine them individually. This spraying process is comparable to the transmission of a cold virus by sneezing.

Im Focus: ScanCut project completed: laser cutting enables more intricate plug connector designs

Scientists at the Fraunhofer Institute for Laser Technology ILT have come up with a striking new addition to contact stamping technologies in the ERDF research project ScanCut. In collaboration with industry partners from North Rhine-Westphalia, the Aachen-based team of researchers developed a hybrid manufacturing process for the laser cutting of thin-walled metal strips. This new process makes it possible to fabricate even the tiniest details of contact parts in an eco-friendly, high-precision and efficient manner.

Plug connectors are tiny and, at first glance, unremarkable – yet modern vehicles would be unable to function without them. Several thousand plug connectors...
