Researchers at the Technical University in Munich have created a microchip sensor which is able to monitor tumor growth based on oxygen saturation. Electrodes on the sensor record oxygen levels. Implanted near the tumor itself, the microchip will be able to reduce hospital visits by sending collected data directly to doctors wirelessly through an external unit.
Project Manager Sven Becker told the BBC that the chips will mainly be used with the purpose of monitoring tumors that are hard to remove because of location. Tumors located close to the spine, for example, increase the risk of cutting a nerve if taken out surgically. In the future, scientists hope to create a medication pump that connects to the microchip. The pump would allow medicine to be delivered more directly with fewer side effects. Researchers hope to enact this focused, less aggressive targeted treatment within 10 years.
