Biomimetic synthesis of BaSO4 nanotubes using eggshell membrane as template

BaSO4 nanotubes were biomimetically synthesized by the combined assembly of eggshell membrane and C12H25SH. The products were tubular structure with the external diameter of 90-140 nm and the length of 1.5-2.5 mum. The formation mechanism was also investigated. It provided a novel method for the fabrication of inorganic oxysalt nanotubes.
