Helixes with highly ordered substructures were found sporadically during pptn. of self-assembled SiO2-Ba carbonate biomorphs. Identical morphologies are already known and cited in the literature as helical calcite structures, formed by the influence of chiral phosphoserine copolypeptides. Yamamoto et al. claim that the handedness of the helixes can be tuned by the chirality of the amino acids in the phosphoserine copolypeptides. Optical and SEM, energy-dispersive x-ray anal., Tg, as well as proton and C NMR were performed on selected twisted ribbons, proving that these helical superstructures, in shape identical to the helical calcite morphologies reported by Yamamoto et al., do not consist of inorg. material but of an org. polymer, representing plastic abrasion caused by scratching glass pipets along plastic surfaces.
