Organic and natural materials for bioelectronics

Organic electronics offer materials and devices that can be suitable applied in healthcare, biochemical sensing, wearable electronics and drug delivery. This presentation will showcase various applications developed by our research group in these areas. Our approach begins with the fundamentals properties of natural materials, applying them on the skin for drug delivery systems, in-vivo wound through animal models, real-time bio-potential monitoring, or biochemical sensing. I will present prototype devices including a skin-patch made from the silk-extracted cocoons Fibroin/Sericin applied on skin as a patch,1 for ECG monitoring,2 a voltage-controllable implantable drug delivery strip, and a calibrated graphene biochemical swab for IL-6 detection in real saliva samples.3 Our method focuses challenge of continuous, unobtrusive monitoring of biochemical human parameters. I will show the in-progress work of in-vein / in-vessel prototypal devices within the framework of the EU-funded project IV-LAB.4 Finally, I will introduce a new fundamental research direction involving the use of unconventional materials for biosensing and computing applications. Examples will include the use of minimal peptides (proteinoids)5 and bacterial cellulose,6 illustrating the different approach behind our research.
