Speaker

Prof. Magnus Berggren (Linköping University)

Biography

Magnus Berggren received his MSc in Physics and PhD in Applied Physics in 1991 and 1996, respectively, from Linköping University in Sweden. After that, he joined Bell Laboratories, USA, for postdoctoral studies focusing on the development of organic lasers. In 1997, he co-founded Thin Film Electronics AB and for one and a half years he served the company as its managing director with the prime mission of developing printed electronic memories. Then, he returned to Linköping University and also joined Acreo (today RISE) to establish the research in printed and paper electronics, in part supported by the paper- and packaging industry. Since 2002, he holds the professorship in, and is the director of the Laboratory of, Organic Electronics, Linköping University, today including about 140 people organized in 12 different research groups. Magnus Berggren is one of the pioneers behind Paper Electronics, Organic Bioelectronics and Electronic Plants and in 2012 and 2018 he became an elected member of the Royal Swedish Academy of Sciences and the Royal Swedish Academy of Engineering Sciences (IVA), respectively. In 2014 he received the Marcus Wallenberg Price and in 2017 he received the IVA gold medal. He has co-founded more than 10 companies in the areas of Organic Energy Materials, Internet of Things and Biotechnology. Since January 2022, Magnus is the director for the Wallenberg Initiative Material Science for Sustainability, which is a 300 Million USD national research program operating from 2022 through 2033 composed of research projects, strategic recruitments, guest professorships and collaboration initiatives with industry.

[Abstract]

Organic Electronics provide a wide array of signal translation properties and features making the communication between biology and technology going far beyond what is possible with traditional metal electrodes and inorganic electronics. In addition, organic electronic materials also provide necessary biocompatibility and biostability characteristics, represented by softness, flexibility, and chemical tunability. However, high-performing signal transfer across the biology-technology gap also relies on close integration, proximity, and selective connection to targeted biological components, which is problematic when (organic) electronics is manufactured and defined on substrates and carriers.

Here, the concept of in vivo-manufacturing of substrate-free organic bioelectronics is reported based on a set of recently synthesized and explored thiophene-based trimers. Those trimers have been equipped with proper side groups aiding integration with walls, clusters, and larger systems of cells possible in a tight and selective manner. Electrodes and electroactive structures are then derived using available metabolic components, of the biological system, to power the polymerization. We can control aggregation, in-biding to cells and polymerization in a highly balanced manner, which together provides us with a protocol to achieve complex structures using cells and systems thereof as the template to generate electrodes and electronic structures. The resulting substrate-free bioelectronics are highly conductive and offer novel routes for bio-integration. We will report substrate-free organic bioelectronics applied to various cell lines and animal models.
