An array of different thiophene-based trimers has been synthesized that combines electronic, chemical, and pharmaceutical functions. These electro-active pharma-materials (e-NP) have been applied onto and into various cell and tissue systems to form seamless bioelectronics that is amalgamated with biology. Selectivity to specific biological components and structures enables us to form well-defined electroactive structures and devices that promise for radically new tools to record and stimulate biological functions, such as neuro-signaling.

In addition, we have developed the organic electronic ion pump that enables the translation of electronic addressing signals into the delivery of bio-relevant ions and charged biomolecules. The OEIP has been developed into different form factors to enable stimulation and therapy targeting a range of neuro-related disorders and diseases.

The objective with the e-NP and the OIEP bioelectronic techniques is to provide minimal invasiveness and selective signal translation at the biology-technology interface.

The fundamentals of, and the results from applications, of the e-NP and OEIP technologies will be reported and discussed.
