Tianhong Chen and Björn M. Reinhard Characterizing the Lateral Friction of Nanoparticles on On-Chip Integrated Black Lipid Membranes Small 9
The diffusion behavior of gold nanoparticles (NPs) functionalized with different surface chemistries on black lipid membranes is investigated by dark-field microscopy. NPs tethered in close vicinity to the membrane exhibit a substantial lateral frictional drag that reduces their lateral mobility. The membrane model system facilitates a systematic investigation of the influence of NP size, shape, charge, and surface composition on the lateral mobility.
