Representative AFM images and schematics for dilute l-5-HTP-functionalized surfaces. Substrates (a) before and (b) after 5-HT7 receptor vesicle immobilization. The sizes of features observed are consistent with vesicles sized prior to capture (see text and Supporting Information). Discussions of the schematics generated from molecular dynamics simulations and the captured vesicle volumes are given in the Supporting Information.
