Abstract
We report on microscopic imaging of phospholipid membranes. To achieve nonlabel, noncontact, and high spatial resolution imaging of the membranes, we use optically excited localized surface plasmons as a virtual measurement probe to obtain the local refractive index. This enables significantly higher lateral resolution of . We reveal that the developed microscope has the capability of observing lipid bilayers with thickness of deposited into the gaps in a patterned lipid bilayer with thickness of . We find that the thickness resolution against the deposited lipid bilayer is .
