The use of organic semiconductor devices as photocapacitors is an innovation with promising applications in neural interface technologies, particularly for retinal prosthetics. Here we report the characterization four distinct photocapacitor device architectures that were fabricated by depositing ultra-thin layers poly-3-hexylthiophene and C60 fullerene various combinations on tin-doped indium oxide (ITO) electrodes. We used electrophysiological recordings to measure intrinsic photoresponse...
Abstract Organic semiconductors have emerged as promising neural interfacing materials due to their innate biocompatibility, soft mechanical properties, and mixed electron/ion conduction. One exciting application is use artificial photosensors for retinal prostheses via optically induced neuromodulation. In this study, the optoelectronic properties of six organic semiconductor polymers small molecules, split into donor/acceptor pairs that form candidates a trichromatic retina closely mimics...
The use of nanostructured materials for targeted and controlled delivery bioactive molecules is an attractive alternative to conventional drug administration protocols, enabling selective targeting diseased cells, lower administered dosages, reduced systemic side effects. Although a variety nanocarriers have been investigated in recent years, electroactive organic polymer nanoparticles present several exciting advantages. Here we demonstrate that thin films created from synthesized...
