In past decades, nanoparticles and nanomaterials have been actively used for applications such as visualizing nano/ submicrometer cell structure, killing cancer cells, and using drug delivery systems. It is important to understand the physicochemical mechanisms that govern the motion of nanoparticles on a plasma membrane surface. However, the motion of small particles of <1000 nm on lipid membranes is poorly understood. In this study, we investigated the diffusion of particles with a diameter of 200800 nm on a lipid membrane using cell-sized liposomes. Particle associated liposomes were obtained by applying centrifugal force to a mixture of liposomes and particle solutions. We measured the thermal motion of the particles by phase-contrast microscopy. We found that (1) the particle-size dependence of the diffusion of particles adhering to membranes was better described by the DADL model rather than the Einstein Stokes model, (ii) the diffusion coefficient of a particle Strongly depends on the adsorption state of the particle, such as fully or partially wrapped by the membrane, and (iii) anomalous diffusion was induced by the localization of particles on the neck of budded vesicles.
