Maria Asplund studied Applied Physics and Electrical Engineering at the University of Linköping, Sweden (1997-2003). After the diploma she continued with a PhD at the Royal Institute of Technology, Stockholm (2003-2009) in the group of prof. Hans von Holst. The focus of the PhD project was conjugated conducting polymers as a means to improve neural interfaces. Conducting polymers were tailored for this purpose through the incorporation of biological molecules in the polymers and their biocompatibility, stability and suitability as electrode coatings was evaluated. The polymer development was conducted in close collaboration with the group of prof. Olle Inganäs (Linköping University), co-supervisor of the PhD project, and biological evaluations of the material was performed in collaboration with Karolinska Institutet, Stockholm. Following the PhD, Maria Asplund continued to work as a Senior Researcher at the Royal Institute of Technology. Subsequent projects have ranged from continued work with conducting polymer electrodes to experimental work on cellular behaviour in electrical fields. Maria Asplund also took part in the construction of new laboratory facilities at the Royal Institute of Technology as well as had responsibility for education in the Medical Technology Master Programme. Maria Asplund is a member of the Centre for Organic Bioelectronics (OBOE) since 2005, funded by the Swedish Foundation for Strategic Research.

In Oct 2011 Maria Asplund was appointed as a Junior Fellow at the FRIAS School of Soft Matter Research. Her continued work at FRIAS aims to address specific problems at neural implants with conducting polymer technology. The ambition is to investigate the performance of the polymer materials in the medical situation to fully understand to which extent these materials can be used to contribute to the success of a neural implant. This work is carried out in collaboration with Prof. Thomas Stieglitz at IMTEK Freiburg.

Conducting polymers for neural interfaces

Within the framework of FRIAS, Maria Asplund will continue her work with conducting polymers for neural interfaces. The aim is to move on towards specific applications. Numerous studies explore the versatility of the polymer materials for introducing bioactive species, intricate surface structures and mechanical buffering on metallic electrode surfaces. The ambition here is to pick the most relevant of these ideas to tailor a polymer electrode and prove its usefulness in the real medical situation. The crucial point is to understand if truly soft implants, based on mechanically flexible substrate materials in combination with bioactive soft polymer electrodes is sufficient to allow for long term close contact with the nervous system.
