This PhD work was aimed at introducing electrochemical strategies in the general topic devoted to the characterization of the passage of cell penetrating peptides (CPPs) across phospholipidic membranes. Although positively charged, CPPs are prone to cross lipidic bilayers of real and artificial cells (liposomes) and there is no commonly admitted internalization mechanism so far. Therefore, we first developed electrochemical setups aimed at improving the amperometric detection of redox-taggedCPPs, through optimization of volume and confinement. Additionally, we have made attempts to use patch-clamp inspired setups to monitor the passage of CPPs across a membrane patched from a giant vesicle using ultramicro-electrodes in the close vicinity o...
