Thermal Expansion of Microstructured DMPC Bilayers Quantified by Temperature-Controlled Atomic Force Microscopy

Microcalorimetry of single bilayers: Temperature‐controlled AFM (see images; DMPC=1,2‐dimyristoyl‐sn‐glycero‐3‐phospocholine) of microstructured lipid bilayers allows for the exact determination of the main phase transition temperature of solid supported membranes. The authors show that changes in m...

Zusammenfassung:Microcalorimetry of single bilayers: Temperature‐controlled AFM (see images; DMPC=1,2‐dimyristoyl‐sn‐glycero‐3‐phospocholine) of microstructured lipid bilayers allows for the exact determination of the main phase transition temperature of solid supported membranes. The authors show that changes in membrane thickness, thermal expansion and boundary fluctuations can be determined simultaneously as a function of temperature.
