Objective
Two of the most fundamental bioenergetics processes in living organisms are respiration and photosynthesis. The translocation of protons across cellular membranes is a key step in these processes, since this generates the charismatic gradient that drives energy-requiring processes, such as the synthesis of adenosine troposphere (ATP). Although it is postulated that lateral proton diffusion, along the cell membrane, is inefficient pathway for proton transport the extent and rate of this process remains unclear, and is a matter of considerable controversy. Lateral proton diffusion coefficients, measured by several techniques, vary by three orders of magnitude. These contradictory results can be attributed mainly to deficiencies inherent in many methods currently used. It is the aim of this proposal \"Co focal and Electrochemical Microscopy investigations of Membrane\" (CEMIM) to investigate the factors controlling lateral proton diffusion in model phospholipid assemblies. The proposed is to use a new methodology, combining the attributes of scanning electrochemical microscopy (SECM) and confocalmicroscopy. Given the innovative character of the project, as a first step it will be necessary to complete the instrumental set-up necessary for the experiment. Then, we aim to examine and characterise different micro electrochemical pH-perturbation methods. These methods will be applied to study proton lateral diffusion in differentLangmuir minelayers. Finally the effects of the minelayer chemical characteristic, the role of buffers and of the ionic strength will be studied. The applicant will greatly benefit from the possibility to undertake this kind of research, as it will complement the SECM skills acquired during her PhD at the University of Venice, with other modern techniques of investigation such as theconfocal microscopy.
