Abstract
Nanotubes are formed by self-assembly of α-lactalbumin milk protein following a different route than established for the hydrolysis which involves V8 enzyme, phosphate buffer and appropriate amounts of calcium at neutral pH. The resulting nanotubes are used as templates for the growth of conductive silver nanotubes. TEM, SEM-EDS, AFM and FTIR are used for characterization.
Highlights
Molecular self-assembly occurs by spontaneous diffusion and specific association of molecules driven by non-covalent interactions such as hydrogen bonding, electrostatic interaction, hydrophobic packing, aromatic stacking and van der Waals forces
Nanotubes were formed by self-assembly of α-lactalbumin milk protein following a different route for the hydrolysis which involves V8 enzyme, phosphate buffer and the presence of appropriate amounts of calcium at neutral pH
The optimal amount measured as calcium to α-lactalbumin molar ratio was 9, only close to this value appeared a translucent gel indicating the formation of nanotubes
Summary
Molecular self-assembly occurs by spontaneous diffusion and specific association of molecules driven by non-covalent interactions such as hydrogen bonding, electrostatic interaction, hydrophobic packing, aromatic stacking and van der Waals forces.
