In January this year, Viviane Forsberg became a visiting postdoc researcher fellow at Northwestern University, Chicago, USA. She defended her doctoral thesis in Chemical Engineering in the Fall 2019 supervised by Prof. Magnus Norgren at Mid Sweden University. Her research area is still connected to the topic of her PhD studies around liquid-phase exfoliation of 2D materials, especially molybdenum disulfide, a bioresorbable material that can be employed in biomedical applications.

– The field of research that I´m carrying out in USA is called transient electronics or bioresorbable electronics for medical applications and is expected to last for up to two years. My research is done in collaboration with Mid Sweden University in Sundsvall, Sweden, says Viviane Forsberg.

Bioresorbable electronic systems represent an emerging class of technology with potential to create important, new categories of devices with powerful modes of use in emergency medicine, recovery and rehabilitation.

– These systems are constructed entirely with materials that dissolve completely, with programmable rates after insertion into the body. Wide-ranging options in sensing, wireless data transmission, power supply and actuation are now possible in devices that exhibit excellent biocompatibility in cell level toxicity studies and animal trials, says Viviane Forsberg.

The devices provide high performance, stable operation for a clinically relevant timeframe, and then completely resorb to eliminate unnecessary device load on the body in a manner that avoids risks associated with secondary surgical extraction.

– Compared to the conventional devices, the use of bioresorbable devices, or in other words, sensors that disappear by natural processes of degradation in the body, offer the advantage to reduce the costs and risks associated with the retrieval of the device when they are no longer needed, says Viviane Forsberg.

The research is developed in the group of Prof. John Rogers at Northwestern University. Viviane´s research is financed by ÅForsk and J. Gustaf Richert Foundations. Recently she received grants from the Gunnar Sundblad Foundation. Mid Sweden University and Northwestern University are also partly financing this project.
