A polymerizable unit that yields an electrochemically responsive polymer (advantageously pyrrole) is anchored by polymerization within a polycaprolactone matrix to form an electroactive scaffold upon which cells can be cultured and in which the micro- and nano-topological features of the polycaprolactone matrix are preserved. A scaffold manufactured in accordance with the preferred embodiment can support Schwann cells, which produce nerve growth factor when electrically stimulated. Nerve growth factor has been demonstrated to promote the regeneration of nerve tissue. By implanting the scaffold on which Schwann cells have been cultured into damaged nerve tissue and applying a voltage across the scaffold, nerve growth factor is produced, thereby promoting repair of the damaged nerve tissue.

Electroactive polymeric scaffolds and method for delivering nerve growth factor to nerve tissue

Wireless and non-wireless drug delivery integrated circuits, systems, and methods of delivering therapeutic pharmaceutical compounds are provided. The system can include a control module, a wireless drug delivery integrated circuit, a first electrode and a second electrode that are both attached to the wireless drug delivery integrated circuit, an electroactive polymer, and a pharmaceutical compound. The electroactive polymer and the pharmaceutical compound can be formed as films on one of the electrodes and, when placed in a solution, a voltage potential can be applied across the electrodes causing the pharmaceutical compound to be released into the solution.

Drug delivery integrated circuit (IC) and system

Embodiments of the present disclosure provide for electroactive supramolecular polymeric assemblies, methods of making electroactive supramolecular polymeric assemblies, methods of using electroactive supramolecular polymeric assemblies, and the like.

A biodegradable electroactive material can be doped with a drug and the drug can be delivered to a living subject by stimulating the material with an electrical potential. The material (in this case a polymer) has an electrochemically responsive oligoaniline block terminated with a carboxylic acid moiety and is linked to an alcohol-terminated diol by an ester bond. Advantageously, the diol is PEG-400, PEG-2000, PCL-530, or PCL-2000.
