We are developing a new label-free bioimaging technique named as electric-double-layer modulation imaging (EDLMI). We previously reported that the technique allowed visualizing 5 nm-thick alkane thin film with improved sensitivity. Here we report application of EDLMI to visualizing biomolecules such as albumin and mouse antibodies.
