de l’Infochemistry Group, ITMO University, St. Petersburg, Russian Federation donnera un séminaire intitulé “Photon to Proton conversion at semiconductor / polyelectrolyte / lipid bilayer interfaces: physico-chemical basis and application for light-induced actuation of pH-sensitive assemblies”, le Jeudi 27 septembre 2018 à 11h00, en salle mezzanine.
Processes at the interface of inorganic solids and polymers mimic a large variety of natural processes such as stimuli responsive behavior, self-healing, actuation, transport and delivery, pH-buffering, but they are not well understood. Polyelectrolyte multilayers are suitable for studying this, as they can be manipulated at will between glassy, rubbery, hydrogel or organogel. We suggest to investigate photocatalytically triggered local pH changes in titania / polyelectrolyte Layer-by-Layer (LbL) / lipid bilayer assembled interfaces, mimicking natural processes in a novel design strategy for inorganic / polymer interfaces.
