Benzene layer-aligned electrochemical transformation of SWCNTs to redox-active macro-walled CNTs: enabling oxygen interference-free monitoring of ROS release from HeLa cancer cells
The search for novel carbon allotropes with unique electrochemical properties remains a key area of research in materials science.
On the origin of the biological effects of time varying magnetic fields: quantitative insights
A spherical cell under the influence of a time varying magnetic field (H) inducing an electric field (E) which results in a force (F) and a corresponding stress Sk on the membrane.
Prudently designed Se@fMWCNT as a peroxidase mimicking nanozyme for distinctive electrochemical detection of H2O2 and glutathione
A Se@fMWCNT nanocomposite with peroxidase mimicking activity was used for the electrochemical detection of H2O2 and glutathione. Both analytes were detected using amperometry at a low potential of −0.2 V, with excellent selectivity and sensitivity.

Drug delivery via a 3D electro-swellable conjugated polymer hydrogel
A glycolated polythiophene, p(g3T2), enables controlled drug loading/release of molecules with molecular weight of 800–6000 Da, due to large, reversible volume changes during electrochemical doping.
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.
