Control of size and shape of colloidal nanocrystals is important, but there are some other equally important—if not more important—issues to be considered.

In this work we have presented a collagen-nanotube composite which has the potential to serve as a scaffold for tissue regeneration. The biofunctionality (shape maintenance) associated with this biocomposite and the observation that the composite induces mineralization of HA crystals in vitro opens a wide range of new possibilities concerning its use for the tissue engineering of bone.

A sol–gel process allows bionanoparticles such as turnip yellow mosaic virus, cowpea mosaic virus, tobacco mosaic virus and ferritin to be incorporated into silica, while maintaining the integrity and morphology of the particles.

Dye-sensitized solar cells (DSCs) based on a photocathode of Ni0.94Pt0.06 films that were prepared by reaction of chemically plated Ni films with H2PtCl6 solution have shown higher conversion effi ciencies than the DSC based on a pure Pt fi lm obtained by conventional thermal decomposition indicating that the as-prepared Ni0.94Pt0.06 films (with a low Pt loading of 5.13 μg/cm2) is a promising photocathode material for commercial DSCs.
