Rod-like architecture and helicity of the poly(C)/schizophyllan complex observed by AFM and SEM.
Microscopic studies of the complex between poly(C) and schizophyllan (SPG), employing both AFM and SEM, revealed that the complex takes the same rod-like architecture on the mica surface as those of the renatured SPG and the original triple helix of SPG, indicating that the complex also has a helical structure. The SEM observations showed the helical pattern on the rod surface, only when the sample was metal shadowed. The pitch evaluated from the image is comparable with that obtained from crystallographic data. The ability to visualize the helical structure can be explained from the hypothesis that the platinum grains may assemble on the sample using the molecular surface of the SPG (or complex) as the template.
