Figure 1. Typical synthesized chiral SiO₂ nanomaterials. (A) Schematic models for left- (left) and right-handed (right) chiral mesoporous silica derived from the helical propellerlike packing of chiral amphiphilic molecules.

(B) TEM images of self-assemblies of amphiphilic surfactants of 16-2-16 and their transcription into twisted and helical SiO₂. This figure is used with permission from the American Chemical Society^[13]. (C) A schematic model for chiral nematic mesoporous SiO₂ films templated from the nematic ordering of nanocrystalline cellulose (NCC). This figure is used with permission from John Wiley and Sons^[14]. (D) Imprinted chiral SiO₂ nanotubes synthesized using a chiral N-stearoyl L-serine (C₁₈Ser) anionic surfactant template.
