"Individual cellulose macromolecules were successfully visualized on a highly oriented pyrolytic graphite (HOPG) surface by tapping-mode atomic force microscopy under ambient condition. Monomolecular-level dispersion of cellulose chains was achieved through the momentary contact of dilute cellulose/cupri-ethylenediamine (Cu-ED)solution onto the HOPG substrate," scientists in Fukuoka, Japan report.

"Both concentrations of cellulose and Cu-ED provided critical impacts on the topographical images. Single cellulose chains with molecular height of ca. 0.55 nm could be observed under the optimal conditions, showing rigid molecular rods with a unique morphology of hexagonal...
