The main goal of ProBIOnCell is to broaden my expertise by performing state-of-the-art scientific research in the fields of applied physics and cell biology by implementing functionalized AFM tips with natural and/or synthetic ionophores incorporated into biomimetic membranes, for electrochemically testing their ability to detect target ions in cellular cultures, so that to probe and localize cell membrane ion channels, gap-junction and focal adhesion on mouse primary cardiac fibroblast cells. Advancing the characterization of biological cells allows for a deeper understanding and modeling the physiological behavior of biological tissues, with huge potentials in biomedicine for improving the management of cardiovascular diseases and their treatment. From a personal perspective, this project contributes to my first international mobility, which is fundamental for unlocking new career perspectives towards a permanent research position and will be implemented at the National Institute of Materials Physics (NIMP) of Bucharest. In order to achieve the main goal of ProBIOnCell some specific objectives are foreseen: O1. Membrane synthesis and ionophores incorporation. Bilipid membranes, hydrogels and liposomes will be synthesized and the incorporation of ionophores investigated. O2. Functionalization of electrodes and AFM tips. This objective involves the deposition or bottom-up construction of the membrane with embedded ionophores at the surface of electrodes and AFM tips. O3. Development of suitable control healthy and pathological fibroblast cell cultures, test the membrane capacity for the detection of target ions by electrochemical methods in the absence and in the presence of inhibitory compounds, and localize ion channels, gap junctions, and focal adhesions by AFM.
