Nanoscale sausage rolls.....

Wrapped polymer chains, consisting of a single strand of a positively charged polymer as stuffing and a thin silicate skin, have been obtained by mixing a polymeric viologen bromide and sodium silicate in a basic medium. The nanostrands, which are 2.5 nm wide and up to 60 nm long, were observed with transmission electron microscopy after Gd3 staining (T. Kunitake et al., March 3; Adv. Mater. 2002, 14, 344-346).
