Nanoparticles induced raft formation in phospholipid liposomes

Motivated by the general interests in endocytosis, virus transfection and utilization of nanoparticles as cargo for drug delivery, this study focuses on the binding of nanoparticles to model lipid bilayers and the interactions between them. Exploring on ensemble level, with the help of calorimetry, and on molecule level, spying by fluorescence probes, we surprisingly discovered that the bound nanoparticles captured and slaved the lipids underneath, which results in lipid packing fluctuations, thereby producing rafts in the bilayers. Bearing this insight in mind, we expect coupled motions of lipid and nanoparticles to occur. Even going further, collective responses of lipid molecules cast light on the role of membrane as a sensor to an external stimulus.
