Despite surgery and subsequent treatment with chemotherapy and radiation, the majority of patients experience recurrence of malignant brain tumours. Researchers at Linköping University, Sweden, and the Medical University of Graz, Austria, have shown in cells in culture that an ion pump can deliver drugs more accurately, which gives less severe adverse effects in chemotherapy. The results have been published in Advanced Materials Technologies. This is the first time an ion pump has been tested as a possible method to treat malignant brain tumours. We used cancer cells in the lab, and the results are extremely promising. However, it will probably take five to ten years before we see this new technology used in treatments for brain tumours , says Daniel Simon, associate professor at the Laboratory of Or

Buffer Layer Nanoparticle Inks for Printed Electronics
Sponsored by Avantama AGFeb 12 2014
Printed electronic devices consist of multiple layers of functional materials. Each of these materials must be optimized to both perform well in the device, and to be printed as easily as possible. Other factors such as interactions between layers must also be taken into consideration.
Custom nanoparticle inks, such as those available from Avantama, are ideal materials for printed electronics. Avantama’s expertise in materials development can help with the creation of the ideal functional materials for printed devices.
The hole transport layer (HTL) must ensure good transport of holes between the active layer and the electrode whilst blocking electrons, whereas the electron transport layer (ETL) ensures an efficient electron transport whilst blocking holes. State-of-the art materials include organic PEDOT-PSS as HTL and e.g. vacuum-processed zinc oxide (ZnO) as ETL.
