About this collection
Bioelectronics, as the name suggests, is a research area on the interface between biology and electronics. It is an interdisciplinary field that combines not only biology and electronics but also many disciplines such as chemistry, physics, materials, and information technology. The aims of bioelectronic research are usually twofold: firstly, studying the electronic processes of biological systems, including the electronic characteristics of biological molecules, information storage and transmission in biological systems, and thus developing new information technologies based on the principles of the biological systems; the second is to apply the theories and technologies of electronic information science to solve biological problems, including the acquisition and analysis of biological information, as well as the regulation of various biological processes. The fundamental mechanism underlying all kinds of bioelectronic processes, including transduction of signal and/or energy, relies on the interfacial properties of materials. The themed collection on bioelectronics across Journal of Materials Chemistry B and Journal of Materials Chemistry C is devoted to the cutting-edge research with a focus on bioelectronic materials.
This Journal of Materials Chemistry B and Journal of Materials Chemistry C themed collection is Guest Edited by Dr Eleonora Macchia (0000-0002-1534-7336, University of Bari, Italy), Professor Hong Liu (0000-0002-9841-1603, Southeast University, China), Professor George Malliaras (0000-0002-4582-8501, University of Cambridge, UK) and Professor Anna Maria Pappa (0000-0002-7980-4073, Khalifa University of Science and Technology, UAE). We hope that this collection will give readers an overview of some of the most recent work concerning bioelectronic materials and will help to promote exciting research in the field.
