In this protocol, we provide a detailed step-by-step bacterial surface imaging and molecular analysis procedure. With SPM (scanning probe microscopy)-based dynamic force microscopy (DFM) imaging, we achieved a so far unprecedented resolution of ~1 nm on the outer surface layer of Tannerella forsythia and monitored the production of curli fibers on Escherichia coli in physiological conditions. Moreover, using these immobilization methods, single-molecule force spectroscopy experiments were conducted on living bacterial cells.
