Lipid phase behavior as a function nanoparticle loading determined by calorimetry. Lipid bilayer phase behavior of DPPC/AgNP vesicles (30 mM DPPC) was determined by differential scanning calorimetry (DSC) for a single heat/cool cycle at 1°C/min. The tilted gel to rippled gel pre-transitions and the rippled gel to fluid main transitions (melting) are visible. The pretransition and melting temperatures were taken at the point of maximum heat flow.
