Atomic force microscopy images of Streptococcus mutans ATCC 25175^T colonizing single wall carbon nano tube-coated glass bead (SWCNT-GB). (a) SWCNT-GB colonization by Streptococcus mutans ATCC 25175^T after three hours of incubation (adherent S. mutans); (b) SWCNT-GB colonization by S. mutans ATCC 25175 ^T after 24 hours of incubation (S. mutans biofilm); (c) three-dimensional view of the same area of (b).
