Abstract In this work, a novel conductive polymer composite consisting of poly(3,4-ethylenedioxythiophene) doped with dodecylbenzenesulfonic acid (PEDOT:DBSA) for bioelectronic applications was prepared and optimized. The PEDOT:DBSA possesses superior biocompatibility toward cell culture electrical characteristics comparable to the widely used PEDOT:PSS. cross-linking processes induced by cross...

Current biosensor developments can be summarised by different trends. For traditional enzymatic biosensors such as glucose sensors, steady improvements of well known basic principles have been made in order to achieve better sensor stability. On the other hand, new affinity sensors such as nucleic acid sensors, transmembrane sensors, and sensors utilising whole cells or even cell networks have ...

merging Brain-Machine-Brain Interfaces (BMBIs) are promising alternative to study the neural activity underlying cognitive functions and pathologies, detecting mind driven decisions, etc. A BMBI covers many engineering and medical science disciplines. It includes biomedical circuits and systems, biosensor interfaces and devices, biosignal and bioimage processing, and bioinformatics, bioelectron...

Graphene is a promising material possessing features relevant to bioelectronics applications. Graphene microelectrodes (GMEAs), which are fabricated in a dense array on a flexible polyimide substrate, were investigated in this work for their performance via electrical impedance spectroscopy. Biocompatibility and suitability of the GMEAs for extracellular recordings were tested by measuring elec...

We explore the electrical rectification of large amplitude fluctuating signals by an asymmetric nanostructure operating in aqueous solution. We show experimentally and theoretically that a load capacitor can be charged to voltages close to 1 V within a few minutes by converting zero time-average potentials of amplitudes in the range 0.5-3 V into average net currents using a single conical nanop...

In bioelectronics, conducting polymer coatings allow the reduction of impedance metallic electrodes and facilitate translation bioelectrical signals at their interface. Such can be made using thin film deposition from a solution or direct synthesis via electrodeposition. The electrical control over offers possibility for fine-tuning film's thickness structure. However, mechanical stability such...

Flexible bioelectronics exhibit promising potential for health monitoring, owing to their soft and stretchable nature. However, the simultaneous improvement of mechanical properties, biocompatibility, signal-to-noise ratio these devices monitoring poses a significant challenge. Hydrogels, with loose three-dimensional network structure that encapsulates massive amounts water, are solution. Throu...
