Forskningsöversikt (refereegranskat)abstract
- During the last two decades, organic electroactive materials have been explored as the working material in a vast array of electronic devices, promising low-cost, flexible, and easily manufactured systems. The same materials also possess features that make them unique in bioelectronics applications, where electronic signals are translated into biosignals and vice versa. Here we review, in the broadest sense, the field of organic bioelectronics, describing the electronic properties and mechanisms of the organic electronic materials that are utilized in specific biological experiments.

- Complex patterning of the extracellular matrix, cells, and tissues under in situ electronic control is the aim of the technique presented here. The distribution of epithelial cells along the channel of an organic electrochemical transistor is shown to be actively controlled by the gate and drain voltages, as electrochemical gradients are formed along the transistor channel when the device is biased.

- An electronic detachment technology based on thin films of a poly(3,4-ethylene-dioxythiophene) derivative is evaluated for controlled release of human epithelial cells. When applying a potential of 1 V, the redox-responsive polymer films detach and disintegrate and at the same time release cells cultured on top in the absence of any enzymatic treatment with excellent preservation of membrane proteins and cell viability.

Translating Electronic Currents to Precise Acetylcholine-Induced Neuronal Signaling Using an Organic Electrophoretic Delivery Device

Tidskriftsartikel (refereegranskat)abstract
- A miniaturized organic electronic ion pump (OEIP) based on conjugated polymers is developed for delivery of positively charged biomolecules. Characterization shows that applied voltage can precisely modulate the delivery rate of the neurotransmitter acetylcholine. The capability of the device is demonstrated by convection-free, spatiotemporally resolved delivery of acetylcholine via a 10 mu m channel for dynamic stimulation of single neuronal cells.
