Abstract
Organic semiconductors are promising for interfacing with biological systems because they are biocompatible, printable and their optical properties tuned. We developed a bio-photoelectrolytic platform based on semiconducting polymer thin films, onto which neuroblastoma SH-SY5Y cells were cultured immersing both in an aqueous biological medium. It was possible to inhibit cell proliferation by 50% in this cancer cell line by subjecting the platform to a series of light pulses over time. Light stimulation was found to increase the concentration of calcium ions inside the cells by three times. The platform also enabled to measure bio-electrical signals. The bio-photoelectrolytic platform and the effective use of light stimulation may open new avenues for in vitro light control/manipulation of cell behaviour, for the development of future novel non-invasive tools for application in biosensing, regenerative medicine and cell-based therapy, and for cancer progression control and therapy.
