Public lecture at the Chemical Society in Lund by Tommy Nylander Lund University, Sweden Professor of physical chemistry and Reciever of the Norblad-Ekstrand medal Title: “Reflections on the biointerface: Structure, interactions and processes” Day: Thursday October 19th Time: 18:00 Place: Hall C, Chemical Center, Naturvetarvägen 14 Abstract Biological membranes do not only occur as planar bilayer structures, but bilayers have also been shown to, depending on the lipid composition, curve into intriguing 3D structures. In fact the important role of curvature of lipid membranes have been increasingly been recognized. Understanding biological implications of such curved lipid interfaces as well as exploiting their full potential in applications, for e.g. drug delivery and other biomedical applications, poses a challenge that requires the development of novel, well-defined and versatile model system. We will discuss how this can be achieved by the supporting surface topology, e.g. vertical nano-wire arrays, or by changing the lipid composition or by introducing components, e.g. responsive particles, which can alter the curvature as a response to the environment. We will discuss how the lipid self-assembly structure can be change in desired way by adding a particular type of lipolytic enzymes. Here the (oil) triglyceride aqueous interface is important also for other processes like emulsification. Our results show that uptake of water in the triolein phase can occur and this can be affected by the presence of lipolytic enzymes. Info The lecture is open to the public and will be held in english. After the lecture there will be an informal reception at the Centre for Analysis and Synthesis (CAS), where you can meet the other attendants (OBS! The lecturer is unfortunetly busy elsewhere this time and will NOT attend the reception). Pea soup with punsch and pancakes (50 SEK) will be served, as well as other refreshments,. Register for the reception no later than Monday 16/10 by sending an e-mail to anita.hoang ‘at’ chem.lu.se Find the lecture hall here. Entrance E at Naturvetarvägen 14 will be held open a short time before the lecture for visitors without access-cards. Welcome!
